Overview
Through an agreement with the European Space Agency (ESA), some of ECHO's data providers have access to MERIS data. For more information about MERIS, check out the links in the sidebar to the right.
MERIS metadata is public via Reverb search, however, accessing the data is a two step process. First you must have a URS account, then you must be authorized to access data holdings by either Level 1 and Atmosphere Archive and Distribution System (LAADS) or the Ocean Biology Processing Group (OBPG).
Either system can be used to apply for MERIS data access. Once you have been granted access, you may search for MERIS data via Reverb and directly access MERIS from either of these data centers.
For full terms and conditions of the ESA Agreement, see the link in the side bar to the right.

Searching For MERIS Data
- Vist the Reverb Home Page and log into via this link.
- Search for the MERIS datasets using the Search Terms box from the Reverb homepage or just paste the following link in a new browser tab: http://reverb.echo.nasa.gov/reverb/datasets#utf8=%E2%9C%93&new_view=true&spatial_map=satellite&spatial_type=rectangle&keywords=MERIS
- In general you will be interested in a specific geographic region, select that region using the map on the front page. For more information about using the spatial search options, see this link. Similarly, to narrow your search to a specific date/time range, please refer to the instructions here.
- If you have been approved for MERIS access, you can use Reverb as explained in the tutorial to download granules of interest to you. Information on that process can be found starting here.
