ASAR Level 0 Product Analysis for Image, Wide-Swath and Wave Mode

Kurzfassung

ENVISAT/ASAR data for all five operational modes (Image, Wave, Alternating Polarisation, Wide-Swath and Global Monitoring) are archived in raw format as level 0 products. These products consist mainly of the ASAR instrument source packets and are accompanied with a minimum set of characterizing parameters. The generation of any ASAR level 1 user product starts from the level 0 product as input. The integrity of the long-term ASAR level 0 data archive has to be ensured, i.e. the level 0 products have to be in line with their specification and they should not show any systematic deficiencies. This is the major task of the level 0 product validation activity. This paper focuses on the level 0 product analysis for the Image, Wide-Swath and Wave mode in VV polarization.
