Envisat ASAR Wave Imagette Cross Spectra L1 [ASA_WVS_1P]
The ASAR Wave product is extracted from the combined SLC and Cross Spectra product, ASA_WVI_1P, which is generated from data collected when the instrument was in Wave Mode using the Cross Spectra methodology. The product is meant for Meteo users. The spatial coverage is up to 20 spectra acquired every 100 km, with a minimum coverage of 5km x 5km. The file size has a maximum of 0.2 Mbytes. Auxiliary data include Orbit state vector, Time correlation parameters, Wave Processing parameters ADS, Wave Geolocation ADS, SQ ADS. The product provides a continuation of the ERS-SAR wave mode data. Output: Wavelength range from 20 to 1000 m in 24 logarithmic steps.

Envisat ASAR WS Single Look Complex L1 [ASA_WSS_1P]
The Level-1B data product offered by ESA from the ASAR Wide-Swath Mode (WS) is a multi-look detected product, ASA_WSM_1P, intended to support applications that exploit intensity data. In order to support the development of new applications with the ASAR ScanSAR data, a WSM product providing phase information has been developed and implemented in the ESA ASAR processor - the Wide-Swath Single-Look complex product (ASA_WSS_1P). This product is mainly used for INSAR applications based either on wide-swath/wide-swath pairs or wide-swath/image mode pairs, applications of ocean current mapping, large-area ocean wave retrievals and atmospheric water vapour characterisation. It is important to mention that the standard ESA WSS product is based on the prototype WSS processor developed by Polimi/Poliba, which has also been used to generate prototype products for testing potential and preparing the exploitation of the WSS product. The ESA ASA_WSS_1P product is available as a standard Envisat ASAR product. The ASA_WSS_1P product format is slightly different from other ASAR products since: There are 5 different MDSs, one per sub-swath A "Doppler Grid" ADS has been included to support ocean current mapping applications There are 5 records in the MPP ADS, one per sub-swath There are 5 records in the SQ ADS, one per sub-swath. Other key characteristics of the ASA_WSS_1P product are summarised below: Processing is fully phase preserving Data in the MDSs is sampled in a common grid both in range and in azimuth Standard product is 60 sec long with 80 m az. pixel spacing Auxiliary timeline information has been added in the Main Processing Parameters ADS Elevation antenna pattern correction is applied by default (although the product is a single-look complex). Spatial Resolution: Approximately 8 m slant range x 80 m azimuth.
