Current Release

warn_icon.gif IMPORTANT MESSAGE Sep 23, 2016    OCO-2 Resumes Data Delivery   

OCO-2 Project resumed delivery of calibrated radiances and science retrievals data for archive and distribution at GES DISC, starting with Data Day September 20, 2016. After experiencing anomaly on August 10, and  re-powering on August 14, the instrument had to go through a lengthy decontamination and calibration cycle.  There will exist permanent gap in science data between August 11-20, 2016. Users should be aware that data in the following period, August 21 - September 15, 2016, will be retrospectively processed into version 7r, but it were collected while the calibrator door position was offset.

warn_icon.gif 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 current Level 1B algorithm is Version 5. The current Level 1C, Level 2, and Level 3 products are Version 6.
