Ongoing: Comprehensive Atmospheric Monitoring Program

The comprehensive atmospheric monitoring program is a joint monitoring program between the National Geospatial Intelligence Agency and ASPECT. The purpose of the program is to develop and demonstrate how infrared remote sensing techniques can be used to conduct atmospheric carbon dioxide monitoring. The program will also estimate possible carbon dioxide sources from city sized areas.
