Research Highlights
NASA’s SABER instrument on the TIMED satellite measures temperature and ozone through the middle atmosphere from 20 to above 100 km. More...
The HIRDLS satellite reveals the structure of the Upper Troposphere / Lower Stratosphere (UTLS) region by measuring ozone. More...
Over the past 4 years, the POP group has made observations of OH, H2SO4, HO2, HO2+RO2 and OH reactivity at a number of sites around the globe.
More...
The MOPITT satellite instrument has been routinely monitoring tropospheric concentrations of carbon monoxide (CO) since March 2000.
MOPITT is equipped with gas correlation radiometers

Temperature changes in the stratosphere are an important component of global change, and are closely linked to understanding the behavior of stratospheric ozone. More...
Chemical OSSE studies help to define quantitative measurement requirements for satellite missions. More...
ACD in the News
ACD's Jim Smith has won the 2009 Kenneth T. Whitby Award, given annually by the American Association for Aerosol Research. This award recognizes outstanding technical contributions to aerosol science and technology by a young scientist. Congratulations, Jim!
A report by the National Research Council of the National Academies released on September 29 takes a close look at how air pollution is transported to and from the United States. "Pollution contributions from other continents affecting air quality in the United States are small but significant," says NESL/ACD's David Edwards. More...
David Edwards, Ave Arellano, and Merritt Deeter published a study describing ACD's use of observing system simulation experiments (OSSEs) to simulate exactly how NASA's new GEO-CAPE satellite would improve forecasts of carbon monoxide concentrations. The article was highlighted in the Journal of Geophysical Research - Atmospheres.
Small but Mighty: Virus-sized Pollutants Affect Mexico City Human Health and Climate Air pollution causes significant human health and environmental problems; in megacities, with populations in excess of 10 million, these impacts are magnified. More...
Announcements
Doug Kinnison has been promoted to Project Scientist III. Doug actively supports both the WACCM and MOZART models and is a key member of the WACCM team, as well as contributing to the HIRDLS project. He is a leading contributor to the international Chemistry-Climate Model Validation project (CCMVal) and to the WMO's Ozone Assessment Report. Congratulations, Doug! (October 14)
