He is now an NCAR Senior Scientist with 27 years’ experience in satellite remote sensing of atmospheric composition, with contributions at every stage of mission development: science driven concept, instrument design, authoring science algorithms, and scientific utilization of measurements. He has been a Science Team member on a number of satellite missions, and is especially associated with the NASA Terra Measurements of Pollution in the Troposphere (MOPITT) satellite project. His personal research, reflected in more than 125 peer-reviewed publications, has emphasized investigations of trace gas and aerosol seasonal variations and global distributions, with a particular interest in the effective integration of measurements from different observational platforms using chemical transport models and data assimilation techniques. Edwards is active on numerous panels and committees related to atmospheric chemistry, global change, pollution, and remote sensing. He currently co-leads the NASA GEO-CAPE mission Science Working Group, and contributes to other international missions with the goal of achieving continuous observational coverage of atmospheric composition through a constellation of geostationary platforms. In recent years, Edwards has held a number of leadership positions within NCAR, and currently leads the Atmospheric Composition REmote Sensing & Prediction (ACRESP) section.
