CAR Discover AQ BRDF Measurements V2 (CAR_DISCOVERAQ_BRDF_2)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/n5dd9c13a0lx
DISCOVER-AQ, a NASA Earth Venture program funded mission, stands for Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality.
Description
In recent years, progress in reaching air quality goals has begun to plateau for many locations. Furthermore, near-surface pollution is one of the most challenging problems for Earth observations from space.
However, with an improved ability to monitor pollution from satellites from DISCOVER-AQ, scientists could make better air quality forecasts, more accurately determine the sources of pollutants in the air and more closely determine the fluctuations in emissions levels. In short, the more accurate data scientists have at hand, the better society is able to deal effectively with lingering pollution problems. During the DISCOVER-AQ mission in 2014, the CAR instrument was flown aboard NASA P-3 aircraft and obtained measurements of bidirectional reflectance distribution function (BRDF) at different scales over agricultural and urban areas in Colorado, USA.
