Access to data
For U.S. based scientists
WInSAR is the primary avenue for getting raw SAR data for interferometry purposes available to WInSAR members - especially for targets in the Americas. However, there are many other routes that include writing individual proposals to ESA (need links) and ASF (need links).
ERS-1, ERS-2, and Envisat --WInSAR or ESA Cat-1 process.
Radarsat-1: ASF
- JERS-1: ???
- ALOS: You must go through the Alaska Satellite Facility (ASF) system to request specific data be made available (transferred from JAXA to ASF and from tape at ASF to L1.0 data online). Once it is L1.0 and online, it is available to anybody registered with ASF. This situation is fluid and may change.
UNAVCO archives and makes data available for GeoEarthscope data users, including data from ESA (ERS1, ERS2, and Envisat missions), and the CSA Radarsat. Access to data requires submission of a "mini-CAT1" research proposal. Note: Much of the data requires being both gunzipped AND untarred, even though there is no .tar suffix. GeoEarthscope
