Diagnostic Data Sets

The diagnostic data set comprises spatial subsets computed from Level-2 input and Level-3 output products. The spatial subsets are stored in netCDF files, called DDS granules. The granules cover areas of about 100x100 km square.

The following table describes the three kinds of available DDS products. Two sets are computed from level 2 products (at 1 km PC and 4.6 km ISIN resolutions) and one set is computed from the merged level 3 products (at 4.6 ISIN resolution).
