The Toolsets for Airborne Data (TAD), developed at the Atmospheric Science Data Center (ASDC) at NASA Langley Research Center (LaRC) to promote the airborne data use, has added additional data sets! Now available is the entire NASA Deriving Information on Surface Conditions from COlumn and VERtically Resolved Observations Relevant to Air Quality (DISCOVER-AQ) Campaign including Maryland, Texas, California, and Colorado. The overarching objective of the DISCOVER-AQ investigation was to improve the interpretation of satellite observations to diagnose near-surface conditions relating to air quality. To diagnose air quality conditions from space, reliable satellite information on aerosols and ozone precursors is needed for specific, highly correlated times and locations to be used in air quality models and compared to surface- and aircraft-based measurements. DISCOVER-AQ provides an integrated data set of airborne and surface observations relevant to the diagnosis of surface air quality conditions from space. To order and download the aircraft data sets you can access TAD at:

This intuitive user interface for variable selection across different airborne field studies and includes features to create merge files based on a user’s choice of time base. In addition, the TAD merge feature allows users to generate standard deviation and to process point-by-point uncertainties and limit of detection values.
