Envisat ASAR WS L0 [ASA_WS__0P]
Listed in NASA Earthdata CMR
The WS Mode Level 0 product consists of time-ordered AISPs collected while the instrument was is in Wide Swath Mode.
Description
The echo samples in the AISPs have been compressed to 4 bits/sample using FBAQ. This is a high-rate, wide swath (ScanSAR) mode so data is only acquired for partial orbit segments and is composed of data from five image swaths (SS1 to SS5).
The Level 0 product is produced systematically for all data acquired within this mode. The objective of this product is to offer Level 0 data for possible images processing on another processing site. It includes mandatory information for SAR processing.
