NOAA extends CU climate studies partnership for 5-10 years
Aug 30th
continue joint leadership of CIRES
The National Oceanic and Atmospheric Administration has selected the University of Colorado Boulder to continue a federal/academic partnership that extends NOAA’s ability to study climate change, improve weather models and better predict how solar storms can disrupt communication and navigation technologies.
The selection means that NOAA will continue funding the Cooperative Institute for Research in Environmental Sciences, or CIRES, for at least five years and up to 10 more years. CIRES was established at CU-Boulder in 1967.
The amount of the award is contingent on the availability of funding in the federal budget, but NOAA anticipates that up to $32 million may be available annually. Total NOAA funding is variable from year to year and is based on the number of projects the university proposes and NOAA approves.
Following a competitive process, NOAA selected CU-Boulder to administer the CIRES partnership which leverages university resources to expand understanding of the “Earth system” — the interrelationships among the atmosphere, oceans, land, living things and the sun’s energy.
“Improving our understanding of the Earth system is critically important as the build-up of greenhouse gases in the atmosphere is forcing changes in all of its processes,” said Robert Detrick, assistant administrator of the NOAA Office of Oceanic and Atmospheric Research and chairman of the NOAA Research Council. “The University of Colorado has been an excellent partner to NOAA in pursuing this mission.”
NOAA’s first cooperative institute, CIRES is marking its 45th anniversary this year and is now one of 18 NOAA cooperative institutes nationwide. NOAA competitively funds cooperative institutes at universities with strong research programs relevant to NOAA’s mission. These institutes provide resources and opportunities that extend beyond the agency’s own research capacity.
“Partnership in environmental research with the NOAA Boulder laboratories is the keystone of CIRES research,” said CIRES Interim Director William Lewis Jr. “We have great ambitions in joint research with NOAA over the next five years.”
The partnership allows researchers at CU-Boulder to receive support for research projects that may involve NOAA scientists, primarily at the Earth System Research Laboratory in Boulder as well as other NOAA cooperative institutes.
The CIRES partnership will focus on nine research themes:
- Air quality in a changing environment
- Climate forcing feedbacks and analysis
- Earth systems dynamics, variability and change
- Management and exploitation of geophysical data
- Regional science and applications
- Scientific outreach and education
- Space weather understanding and predictability
- Stratospheric processes and trends
- Systems and prediction models development
“With pressing issues like air quality, climate change and space weather now at the forefront globally, the University of Colorado Boulder is eager to continue this crucial partnership with NOAA,” said CU-Boulder Vice Chancellor for Research Stein Sture. “CIRES is known around the world for advancing our understanding of the complex Earth system and as a premier institution in educating the next generation of environmental scientists.”
NOAA supports cooperative institutes to conduct research, education, training and outreach aligned with its mission. Cooperative institutes also promote the involvement of students and postdoctoral scientists in NOAA-funded research. This unique setting provides NOAA the benefit of working with the complementary capabilities of a research institution that contribute to NOAA-related sciences ranging from satellite climatology and fisheries biology to atmospheric chemistry and coastal ecology.

Fourmile canyon blaze yields new insight into climate change, CU scientists say
Aug 27th
heat-trapping effects of wildfire smoke particles
When the Fourmile Canyon Fire erupted west of Boulder in 2010, smoke from the wildfire poured into parts of the city including a site housing scientists from the University of Colorado Boulder’s Cooperative Institute for Research in Environmental Sciences and the National Oceanic and Atmospheric Administration.
Within 24 hours, a few researchers at the David Skaggs Research Center had opened up a particle sampling port on the roof of the building and started pulling in smoky air for analysis by two custom instruments inside. They became the first scientists to directly measure and quantify some unique heat-trapping effects of wildfire smoke particles.
“For the first time we were able to measure these warming effects minute-by-minute as the fire progressed,” said CIRES scientist Dan Lack, lead author of the study published today in the Proceedings of the National Academy of Sciences.
The researchers also were able to record a phenomenon called the “lensing effect,” in which oils from the fire coat the soot particles and create a lens that focuses more light onto the particles. This can change the “radiative balance” in an area, sometimes leading to greater warming of the air and cooling of the surface.
While scientists had previously predicted such an effect and demonstrated it in laboratory experiments, the Boulder researchers were one of the first to directly measure the effect during an actual wildfire. Lack and his colleagues found that lensing increased the warming effect of soot by 50 to 70 percent.
“When the fire erupted on Labor Day, so many researchers came in to work to turn on instruments and start sampling that we practically had traffic jams on the road into the lab,” Lack said. “I think we all realized that although this was an unfortunate event, it might be the best opportunity to collect some unique data. It turned out to be the best dataset, perfectly suited to the new instrument we had developed.”
The instrument called a spectrophotometer can capture exquisite detail about all particles in the air, including characteristics that might affect the smoke particles’ tendency to absorb sunlight and warm their surroundings. While researchers know that overall, wildfire smoke can cause this lensing effect, the details have been difficult to quantify, in part because of sparse observations of particles from real-world fires.
Once the researchers began studying the data they collected during the fire, it became obvious that the soot from the wildfire was different in several key ways from soot produced by other sources — diesel engines, for example.
“When vegetation burns, it is not as efficient as a diesel engine, and that means some of the burning vegetation ends up as oils,” Lack said. In the smoke plume, the oils coated the soot particles and that microscopic sheen acted like a magnifying glass, focusing more light onto the soot particles and magnifying the warming of the surrounding air.
The researchers also discovered that the oils coating the soot were brown, and that dark coloration allowed further absorption of light, and therefore further warming the atmosphere around the smoke plume.
The additional warming effects mean greater heating of the atmosphere enveloped in dark smoke from a wildfire, and understanding that heating effect is important for understanding climate change, Lack said. The extra heating also can affect cloud formation, air turbulence, winds and even rainfall.
The discovery was made possible by state-of-the-art instruments developed by CIRES, NOAA and other scientists, Lack said. The instruments can capture fine-scale details about particles sent airborne by the fire, including their composition, shape, size, color and ability to absorb and reflect sunlight of various wavelengths.
“With such well-directed measurements, we can look at the warming effects of soot, the magnifying coating and the brown oils and see a much clearer, yet still smoky picture of the effect of forest fires on climate,” Lack said.
