ACDISC: Atmospheric Composition Data & Information Service Center

The Atmospheric Composition Data and Information Services Center (ACDISC) is a portal to the Atmospheric Composition (AC) specific, user driven, multi-sensor, on-line, easy access archive and distribution system employing data analysis and visualization, and other user requested techniques for the better usage of science data.

ACDISC provides convenient access to AC data and information from various remote-sensing missions, from heritage TOMS, SBUV, SSBUV and  UARS datasets, to the most recent data from Aqua AIRS, Aura OMI, MLS, HIRDLS as well as AC datasets residing at other remote archive sites.

In addition to the daily atmospheric chemistry data from individual sensors, ACDISC also provides multi-sensors based merged datasets for some atmospheric parameters, selected under the NASA MEaSUREs project, to study the long-term changes in the atmospheric composition.

Most recently, ACDISC at GES DISC has been assigned to archive and distribute CO2 data produced by the Atmospheric CO2 Observations from Space (ACOS) Task, using radiances from the TANSO-FTS sensor  flown on Greenhouse gases Observing SATellite "IBUKI" (GOSAT).
