Hello Drew, A system issue that developed around the start of the new year affected the transfer of Sentinel-1 data from ESA. This was resolved, and the transfer resumed. However, the backlog of data that resulted took some time to clear, and I suspect this is the cause of the delay in finding new d...

Re: UAVSAR Data Consultation

UAVSAR data available from ASF have been processed at JPL and sent to ASF for distribution. No further processing is done once a product is received at ASF. The only change made is to add a UA_ prefix to a JPL product name. Documentation for the UAVSAR products is available from JPL, and this includ...
