ACDISC: Atmospheric Composition Data & Information Service Center

IMPORTANT MESSAGE Sep 28, 2016 OMI NO2 Reprocessed Data (Version 3.0) released

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC), in partnership with members of the Aura/Ozone Measuring Instrument (OMI) science team, announce the availability of the full data set of the reprocessed OMNO2 Standard Product, which indicates atmospheric nitrogen dioxide (NO₂) concentrations. OMNO2 data are available as Level 2 (orbital swath) data. The OMNO2G data product is a special Level 2 data product where the pixel level data are binned into 0.25^o x 0.25^o global grids without averaging. OMNO2d data are Level 3 data products created with pixel level data of good quality, binned and "averaged" into 0.25^o x 0.25^o degree global grids.

IMPORTANT MESSAGE Jul 24, 2015 Why do my Data Holdings look different?

Accessing your data through the GES DISC web site may seem a little unfamiliar to you to these days, but we can assure you, your data is all still available. The location of the data in the online archive has not changed.

The GES DISC has implemented a new interactive interface to make finding data easier than ever. We've added features like searching by keywords, filtering by criteria such as measurements, processing level and spatial resolution, and sortable data columns so now you can fine tune your search results. To get you started we put together a Help document to introduce you to the new interface. If you have any questions about the new design please contact us using the Feedback link in the upper right-hand corner or contact the GES DISC Help Desk by sending email to gsfc-help-disc@lists.nasa.gov.

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).
