The ESA (A)SAR On-The-Fly (OTF) data processing and dissemination service allows end-users to gain direct access to the (A)SAR archive from the ERS-1, ERS-2 and Envisat Missions.
The data is collection based and allows data browse and download through the treeview as well as via geographical catalogue search based on area of interest and metadata. Data download is available via HTTPS, including bulk download functionality. ESA internal users can use their ESAAD account.
For information on the (A)SAR On-The-Fly service please refer to the OTF FAQ page.

This ASAR Alternating Polarization Medium Resolution Image product has been generated from Level 0 data collected when the instrument was in Alternating Polarisation Mode. The product has lower geometric resolution but higher radiometric resolution than ASA_APP and contains one or two co-registered images corresponding to one of the three polarisation combination sub modes (HH and VV, HH and HV, VV and VH).
This product has been processed using the SPECAN algorithm and contains radiometric resolution good enough for ice applications and covers a continuous area along the imaging swath.
The ASAR AP L0 full mission data archive has been bulk processed to Level 1 (ASA_APM_1P) in Envisat format with the IPF-ASAR processor Version 6.03.
Spatial Resolution: 150 m ground range x 150 m azimuth.
