Creating a Unified Airborne Database for Assessment and Validation of Global Models (ADAM) of Atmospheric Composition.  A MEaSURES project that addresses the critical needs related to the top two activities selected by Atmospheric Chemistry and Climate i.e. (1) a 20-25 year hindcast of tropospheric ozone and aerosols, and (2) a definition of processes that control the distribution of the tropospheric trace gases/aerosols between mid and upper troposphere.  ADAM enables model verification and comparison exercises associated with these activities by providing observational data in appropriate format and temporal and spatial scales along with objectively assessed uncertainties.
