Kick off of an unprecedented month-long collaboration among scientists from EPA, NASA, NOAA, the State of Colorado, and other organizations in Golden, Colorado. The goal of DISCOVER- AQ is to determine if the air quality we breathe on the ground can be measured with satellites from space. In addition to providing technical expertise on measuring air quality, EPA will also evaluate the performance of new hand held sensor technology that is inexpensive and available to the public. Two universities, University of Maryland- Baltimore County and Millersville, are also participating – providing training to our future scientists.
