Solar radiation enters the Earth's atmosphere with a portion being scattered by clouds and aerosols.

Creating a Unified Airborne Database for Assessment and Validation of Global Models of Atmospheric Composition (ADAM)

 

Principal Investigator: Gao Chen, NASA Langley Research Center

 

The proposed activities address 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. Airborne ESDR (Earth System Data Record) products derived from a wealth of publicly available airborne data sets accumulated primarily from NASA airborne field studies, as well as from studies sponsored by NOAA, NSF and international partners over the past two decades, were created.  The proposed project focused on 3 tasks:

 

 (1)  To compile publicly available data sets from NASA airborne campaigns as well as from the other campaigns sponsored by NOAA, NSF and international partners.

 

 (2)  To assemble a measurement evaluation panel, including both measurement experts and modelers from a broad spectrum of institutions and agencies, to provide objective assessment of measurement uncertainties and biases and to determine how to best integrate these observations into forms useful for model comparison.

 

 (3)  To generate a standardized in-situ observational database with best possible matching temporal and spatial scales to model output, which represents snap-shot spatial distributions of trace gas species and aerosol properties of interest.

 

The work on the ADAM project was completed. The ADAM project was migrated to the ASDC where an effort was initiated to re-engineer the components of the pilot system for easier maintenance and enhanced extensibility.

 

ADAM is the prototype for the Toolsets for Airborne Data (TAD) Web Application. Please visit TAD at: https://tad.larc.nasa.gov
