Sentinel-1 products are ingested at ASF as they are received from ESA. These then become available to download immediately. This process is continuous unless there is a problem with our data "pipeline." We recently experienced one of these problems, where the volume of data received from E...

Newer versions should reflect improvements/enhancements/corrections to the processing algorithm. I would suggest that you pick the latest version and only use these data for your analysis.

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...

Hello Drew, Thanks for sharing the results of your project -- we're always eager to learn how data downloaded from ASF are being used. We have a team that has investigated using SAR for ship detection, and I'm sure they'll find your work extremely interesting. I'm anxious to share this with them. Sh...

ASF searches were not working consistently yesterday, September 21. The issue was resolved overnight and functionality has been restored.

Thank you for your patience!

The README file included in each HyP3 InSAR product package is a very good source for this kind of information.

Displacement values are given in meters.

Thank you,

There is no reference map available for Sentinel-1 ASF frames. Because of the dependence on time instead of a specific set of geographic coordinates when assigning frame numbers, "frame drift" can occur over time, where the frame number over the same spot may change. I recommend using Vert...

Please correct me if I'm mistaken, but I assume you are referring to the modified DEM file that is included with the ALOS PALSAR RTC product bundle. This file is a copy of an open-source DEM that was downloaded, modified, and used to perform radiometric terrain correction (RTC) on an ALOS PALSAR gra...
