Data Access
MERIS data can be obtained by several means:

• - download of L1b and L2 RR data of the last 7 days from the rolling archive/EWFS
• - download of L1b and L2 RR data from 2002 until current from the Merci catalogue (one year of data missing)
• - download of L1b FRS data over Europe of the last 7 days from the rolling archive/EWFS
• - ordering L1b and L2 FR data from 2002 until current on CD/DVD from the EOLI-SA catalogue
• - download MERIS binned Level 3 data from the MERIS Level3 demonstration products page
• - reception of MERIS RR data in NRT using a telecommunication link (satellite dish) through the ESA DDS system (contact eohelp@esa.int to get access to the DDS system. See http://dwlinkdvb.esrin.esa.it/DDS/ for technical details).

MERIS RR data are systematically processed after acquisition up to Level 2 and put on the Rolling Archive. They remain there for download for 7 days. After this period they are transferred into the MERCI system. MERCI includes all consolidated MERIS L1b and L2 RR data from 2002 until current for download.

MERIS FR full swath data are systematically processed until L1b for European coverage and can be downloaded from the rolling archive (last 7 days). Historic FR data are processed on demand and delivered on media. They have to be selected in the EOLI-SA catalogue and ordered.

Data Policy
Download of MERIS RR L1b and L2 data and MERIS FRS data over Europe from the rolling archive/EWFS requires a registration with ESA http://eopi.esa.int/esa/esa?cmd=submission&aoname=lbr. More information about the registration can be found on http://eopi.esa.int/esa/esa?cmd=aodetail&aoname=lbr

Once a user has a registered project with EOPI for MERIS RR data access, download of MERIS RR L1b and L2 data from the MERCI system requires an informal application by Email to EOHELP: eohelp@esa.int. EOHELP sends back a user name and password. Ordering of data from the EOLI-SA catalogue and download of MERIS FR data (other than European coverage) from the rolling archive requires an accepted Cat-1 proposal. Proposal can be submitted from http://eopi.esa.int/esa/esa?cmd=submission&aoname=cat1. More information about Cat-1 proposal can be found on http://eopi.esa.int/esa/esa?e=XDXuWvAzMdf1mrTn3WnRZIs3yw9RTGP0TGGYmX3nY2plBLAAh
