Complete Envisat MERIS FRS L1/L2 dataset available online
13 February 2015
The systematic bulk processing of the MERIS Level 2 Full Resolution Full Swath dataset has been completed, and the FRS Level 2 products (MER_FRS_2P) have been made available to users on the ESA centralised dissemination server together with the previously released MERIS FRS Level 1 data (MER_FRS_1P).
The dataset now comprises the complete MERIS FRS Level 1 and Level 2 data archive from the Envisat mission spanning from 17 May 2002 to 08 April 2012. MERIS FRS density maps are available providing an overview of the data coverage.
With the delivery of this additional dataset, ESA is at present offering free access to nearly 340TB of Envisat MERIS Full and Reduced Resolution data for direct download online.
A first quality assessment has been carried out on the entire FRS L1/L2 dataset preceding the release of the Level 2 products. Following recommendations from the MERIS Quality Working Group, segregation of a selection of MERIS FRS L1/L2 products have been performed in order to allow for distinction of data known to be of non-nominal quality without removing them from the archive. A list of segregated orbits and the reasons for segregation is available on the dissemination server together with the data.
A number of corrupted Level 1 (MER_FRS_1P) products have been identified and replaced by nominal quality products. Details of these and other Level 1 products that for quality reasons have been removed from the dissemination servers are also given.
The MERIS FRS L1 and L2 datasets are distributed as follows:
Users already registered for the MERIS FRS service (FTP/HTTP) can access the Level 2 dataset using the same credentials as previously received for the Level 1 data.
