FORT COLLINS — A new, four-episode public television series, “The Crowd & The Cloud,” highlights the Colorado Climate Center’s signature citizen science movement, the Community Collaborative Rain, Hail and Snow Network – better known as CoCoRaHS. The Colorado Climate Center is part of Colorado State University. All episodes of “The Crowd & The Cloud” are available to watch online. CoCoRaHS is featured in episode 1, titled “Even Big Data Starts Small.” The series will also air on public television’s World Channel at 7 p.m. Mountain (9 p.m. Eastern), Thursday, April 6. Check the World channel website for local availability. Hosted by Waleed Abdalati, director of the Cooperative Institute for Research in Environmental Sciences at University of Colorado-Boulder, the series explores and celebrates the revolutionary power of citizen science. Together, average citizens collecting data en masse can help efforts to combat flooding, drought, pollution and more. Watch a trailer. Gauging rain CoCoRaHS, a network of more than 20,000 precipitation spotters, was founded by the Colorado Climate Center in 1998 following a devastating flood in Fort Collins. To participate, citizens young and old use backyard rain gauges to report daily measurements on the CoCoRaHS website. The data collected by CoCoRaHS observers have been used by meteorologists, natural resource planners, farmers, fishermen, insurance adjusters, and many more. “CoCoRaHS started as a local effort to help scientists study storms and precipitation patterns here in northern Colorado,” says Nolan Doesken, Colorado State Climatologist and CoCoRaHS founder. “It has since expanded into an international program with thousands of passionate, dedicated citizens, and together we have had a real and profound effect on publicly available weather information and how we understand everything from floods to drought.” Live post-premiere roundtable April 6 The show’s social media team will live-tweet during its April 6 premiere using #CrowdCloudLIVE. Join producer Geoff Haines-Stiles, series host Abdalati, and CoCoRaHS staff on Facebook at 8 p.m. Mountain (10 p.m. Eastern) for a post-premiere roundtable discussion. Producers of “The Crowd and the Cloud” also created short videos to support CoCoRaHS’ “March Madness,” campaign, in which states compete for the largest numbers of new observers every March. |

Colfax project from Colorado to Speer boulevards starts this week
DENVER — The Colorado Department of Transportation and contractor partner, Brannan Sand & Gravel Company, will begin the Colfax Resurfacing and Pedestrian Improvements project on Colfax Avenue from Speer Boulevard to Colorado Boulevard with signage erected this week.
The $5 million project will consist of milling existing pavement and resurfacing with an asphalt overlay on 3.5 miles of Colfax Avenue, and reconstruction of 96 curb ramps.
“Colfax Avenue is a major road people use to get into the heart of Denver,” said Paul Jesaitis, Region 1 Transportation Director. “That’s why this project is important to us to improve the safety of both motorists and pedestrians. We recognize that there are a lot of businesses and residences along this stretch and it is our goal to minimize impact of the traveling public and ensure that they have access to where they need to go at all times.”
The project will continue through the summer with anticipated completion in fall 2017. Motorists should expect lane and sidewalk closures, and lane shifts.
The project will be done in phases in order to minimize traffic impacts. Normal working hours will be from 8:30 a.m. to 3:30 p.m. Monday through Friday for sidewalks and curb ramps from April through June. After the sidewalk and concrete work is complete, resurfacing will begin in June and continue through September. The working hours in this phase will be from 8:30 p.m. to 5:30 a.m. Sunday through Thursday. All work is weather permitting and schedules are subject to change.
Travel impacts through Friday, April 7, will be:
Colorado Boulevard to York Street: Sidewalk closures are likely throughout the week for work on manholes and valve boxes. Lane closures on Colfax will take place from 8:30 a.m. to 3:30 p.m.
For additional information, call the project information line at 1-844-281-4473, Option 1; email the team at ; or visit the project website and sign up for updates at https://www.codot.gov/projects/colfax-resurfacing-denver.

CSU Tropical Meteorology Project has new co-author, Michael Bell
FORT COLLINS – Colorado State University’s Tropical Meteorology Project welcomes a new face to its longtime seasonal hurricane forecasts: Michael Bell, associate professor in CSU’s Department of Atmospheric Science.
Bell has entered into a research partnership with Philip Klotzbach, the primary author of the seasonal forecasts and verifications, to become the reports’ co-author. Klotzbach is formally a research scientist in Bell’s group at CSU.
Different expertise
Klotzbach and Bell bring different areas of expertise to the prediction and analysis of hurricane phenomena in the Atlantic basin. “Most of the work I have done has been on the weather scale and mesoscale, focusing on intensity and structural changes,” said Bell, who joined the CSU faculty in summer 2016. “Phil’s expertise is on the seasonal and climate timescales; hopefully by working together, we will bridge some gaps and ultimately help advance the science of tropical cyclones.”
Bell holds an M.S. in atmospheric science from CSU and a Ph.D. from the Naval Postgraduate School. He studies the dynamics of tropical cyclones (another word for hurricanes) using Doppler radar and dropsondes, devices that collect high-density data as they fall from aircraft. He has flown into many tropical cyclones as part of his research. Bell’s first flight into a hurricane was Katrina in 2005 as part of a National Science Foundation-sponsored field project, and he flew into several Pacific typhoons during a U.S. Office of Naval Research-sponsored project in 2008. Much of Bell’s work has focused in the Pacific, home to some of the world’s strongest tropical cyclones. He was recently honored with a Presidential Early Career Award to support his research efforts.
Since CSU started issuing seasonal hurricane forecasts more than 30 years ago, the discipline of tropical meteorology has tended toward specialization, Klotzbach said. “By partnering together, we can hopefully cover time scales of what will happen in the next hour to what will happen during the next hurricane season and beyond,” Klotzbach said. “It’s very exciting to have Michael’s expertise on board as an integral part of our work.”
Longtime colleagues
The two hurricane experts have been colleagues and friends for more than 15 years. They were both atmospheric science graduate students at CSU during the mid-2000s. Klotzbach studied under the late William Gray, the originator of the Atlantic seasonal hurricane forecasts, and Bell under Michael Montgomery, formerly of the CSU Department of Atmospheric Science and, since 2006, a professor at the Naval Postgraduate School.
With Klotzbach officially a part of Bell’s research group, they hope to continue a legacy of strong expertise in tropical meteorology at CSU. This is built upon the shoulders of Gray, Montgomery and Professor Wayne Schubert, recently named to emeritus status, all three of whom have been “very influential in tropical meteorology,” Bell said.
Bell and Klotzbach’s collaboration is not limited to the seasonal forecasts; they are already working on several projects together, studying various aspects of tropical cyclones in their larger meteorological context.
“Our studies are interrelated, and advances in one area lead to advances in other areas,” Bell said. “It is a broader collaboration that goes back to the legacy of Bill Gray, especially, who was widely known for seasonal forecasts but also made tremendous contributions to tropical meteorology in general. Hopefully we can continue in that same tradition.”
The initial 2017 Atlantic Basin seasonal hurricane forecast will be released April 6 during the National Tropical Weather Conference in South Padre Island, Texas.

COLORADO SMOKE OUTLOOK:
Friday, March 17, 2017, 2:25 PM MDTLight to moderate smoke is possible near prescribed fires and small wildfires around the state.
What if there is a wildfire or smoke in your area?
The focus of the Colorado Smoke Outlook is on large fires (e.g., greater than 100 acres in size). Nevertheless, smoke from smaller fires, prescribed fires, and/or smoke from new fires not yet known to CDPHE air quality meteorologists may cause locally heavy smoke. If there is smoke in your neighborhood, see the public health recommendations below.
Public health recommendations for areas affected by smoke: If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly. Fine particulates may reach the Unhealthy category where smoke is heavy. Consider limiting outdoor activity when moderate to heavy smoke is present. People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion. Consider relocating temporarily if smoke is present indoors and is making you ill. IF VISIBILITY IS LESS THAN 5 MILES IN SMOKE IN YOUR NEIGHBORHOOD, SMOKE HAS REACHED LEVELS THAT ARE UNHEALTHY.

http://www.colorado.gov/airquality/wildfire.aspxWinter High Pollution Advisory Program
The Winter High Pollution Advisory Program is coordinated by the Air Pollution Control Division of the Colorado Department of Public Health and Environment.
Winter season air pollution forecasts are issued daily from October 31 through March 31 at 4 p.m. When conditions warrant, forecasts will include information about Action Days and subsequent indoor burning restrictions.
An Action Day for fine particulates, carbon monoxide or ozone indicates that either current air quality is unhealthy or conditions are expected to worsen later in the day or on the next day. Action Days for air pollutants generally indicate that air quality will be in either the Unhealthy or Unhealthy-for-Sensitive-Groups categories according to the Air Quality Index. Action Days trigger mandatory restrictions that limit indoor burning to approved devices only (see indoor burning below), voluntary driving reductions, and public health recommendations.
An Action Day for Visibility alone indicates that the Visibility Standard Index for visual air quality is expected to be poor on the current or following day. An Action Day for Visibility will trigger mandatory restrictions on indoor burning and voluntary driving reductions for the seven-county Denver-Boulder metropolitan area only.
When no advisories are issued, air quality is good or moderate and is expected to remain so during the effective period of the forecast. No restrictions are in place.
Additional Information
ACTION DAYS: An Action Day for fine particulate matter (particulates), carbon monoxide, ozone or other pollutants indicates that either current air quality is unhealthy or conditions are expected to worsen later in the day or on the next day. Action Days for air pollutants generally indicate that air quality will be in either the Unhealthy or Unhealthy-for-Sensitive-Groups categories according to the Air Quality Index. Action Days trigger voluntary pollution prevention measures, which may vary by season, and public health recommendations. In addition, during the winter ‘high pollution day’ season (October 31 to March 31), Action Days trigger mandatory restrictions that limit burning inside the home to approved devices only (see indoor burning below).
Action Days for Visibility alone are issued during the winter ‘high pollution day’ season (October 31 to March 31), only. At the time they are issued (4 PM), action days for visibility indicate that the Visibility Standard Index for visual air quality is expected to be poor on the following day. Action Days for Visibility trigger mandatory restrictions that limit indoor burning to approved devices only and voluntary driving reductions for the seven-county Denver-Boulder metropolitan area .
The VISIBILITY STANDARD INDEX reports the air’s visual quality in the seven-county Denver-Boulder metropolitan area. The visibility standard is 0.076 per kilometer of atmospheric extinction, which means that 7.6 percent of the light in a kilometer of air is blocked. The level must exceed the standard based on a four-hour average for a violation to occur. On the Visibility Standard Index Scale, a value of 101 equates to the 0.076/km standard. Values between 0-50 are good, 51-100 moderate, 101-200 poor and 201-plus extremely poor.
The AIR QUALITY INDEX reports the daily level of air pollution on an hourly basis. The index reports the highest level of either carbon monoxide, fine particulates or ozone depending on which pollutant has the greatest hourly concentration. Values greater than 100 for carbon monoxide, fine particulates and ozone indicate exceedances of the pollutant’s state and federal standards. Air Quality Index values between 0-50 are good, 51-100 moderate, 101-150 unhealthy for sensitive groups, 151-200 unhealthy, 201-300 very unhealthy, and over 300 hazardous.
INDOOR BURNING: On Action Days issued during the winter ‘high pollution day’ season (October 31 through March 31), mandatory restrictions that limit indoor burning to approved devices only generally apply to everyone in the entire seven-county Denver-Boulder metropolitan area below 7,000 feet. The restrictions will be enforced through local ordinances or a state regulation.
The state regulation applies to any community in the seven-county Denver-Boulder metropolitan area that did not have its own mandatory indoor burning ordinance in effect on January 1, 1990. Under this regulation, the only exceptions to the burning restrictions are for residences above 7,000 feet in the seven-county Denver-Boulder metropolitan area; and those who use Colorado Phase III (Phase II EPA) certified woodburning stoves, Colorado approved pellet stoves, approved masonry heaters or those whose stoves or fireplaces are their primary source of heat. For more information on indoor burning, call the Air Pollution Control Division at (303) 692-3100.

For an AQI value that considers all pollutants, please click here .
Ground-level ozone is a summertime air pollution problem that is created when other pollutants from sources like vehicle exhaust, paints, degreasing agents and cleaning fluids react with sunlight. Exposure to ground-level ozone can cause acute respiratory problems, reduced lung capacity and inflammation of lung tissues and can trigger asthma attacks.
Ground-level ozone should not be confused with the protective stratospheric ozone layer miles above the Earth’s surface. This naturally-occurring ozone layer protects the Earth’s surface from excessive ultra-violet radiation.
Do your share and be a part of the solution to the Denver-metropolitan area’s summertime air pollution problems. These easy strategies will help reduce the harmful vapors that react in sunlight to create summertime air pollution:
At Home:
Tightly cap all solvents (paint thinners and strippers, degreasers, and some cleaning products). Solvents contain pollution-causing vapors. Postpone painting, stripping and refinishing projects to avoid the morning and mid-day summertime heat. Better yet, wait until the Fall or Spring. Use water-based products (paints, stains and sealants).
In the Yard:
Delay mowing your lawn to another day. Don’t mow, let it grow! Avoid using high-emitting, gasoline-powered yard equipment. Electric alternatives are an efficient, environmentally-friendly alternative. Use an electric starter or a “charcoal chimney” to start your barbeque grill. Lighter fluid contains a lot of harmful vapors that escape into our air and contribute to summertime air pollution.
On the Go:
Stop at the click when refueling your car. Overfilling your tank often results in fuel spills and always allows unnecessary pollution-causing vapors to escape into our air. Refuel in the evenings after dusk. By refueling after the sun goes down, fuel vapors do not have as much of a chance to “cook” in the mid-day sun and become harmful ground-level ozone. Maintain your vehicle. A poorly-maintained vehicle can pollute as much as 25 times more than a well-maintained one.

Bill Passes Wages on CDOT Projects
Bill Protects Workers’ Wages on CDOT Projects
A bill expanding wage protections for workers on state highway projects passed the House Transportation & Energy Committee on February 1. HB17-1068, sponsored by Rep. Adrienne Benavidez, D-Adams County, specifies that the Colorado Department of Transportation may consider bids, including those for public-private partnerships like the recent US36 project, only if the bid calculates labor costs using locally prevailing wages and benefits. The idea is to prevent lowball bids from companies that don’t pay their employees fair wages.
This bill is intended to protect workers in Colorado so they can earn a good wage and raise their families. It also clarifies the state’s requirement to pay prevailing wages on public projects when they partner with private business – Rep. Benavidez
The committee voted 8-4 to send the bill to the House floor.
