NISAR Data Lives Here

The Alaska Satellite Facility (ASF) is a NASA Distributed Active Archive Center, specializing in SAR data. ASF currently stores over 15 PB of free and open SAR data, and will be the home of NISAR data. It's our mission to make SAR data easy to find, access, process, and interpret.

Tutorials and More

Data

As part of our effort to prepare for the NISAR mission, we are exploring a number of platforms and workflows to produce and provide higher-level SAR products, similar to what will be available from the NISAR mission. We have worked with JPL to ingest NISAR-like sample InSAR products generated from Sentinel-1 data using ARIA. In addition, we have developed HyP3, a cloud-native platform for processing SAR data, and provide users the option to submit specific Sentinel-1 scenes for Radiometric Terrain Correction (RTC) or scene pairs for InSAR processing on demand. We also have RTC products available for a subset of the scenes from the ALOS PALSAR mission.

Sentinel-1 InSAR Products (NISAR-format)

Ridgecrest Earthquake Sequence

Sentinel-1 InSAR (NISAR-format)

Ridgecrest Earthquake Sequence in California, July 2019. Color wrapped interferogram draped over grayscale unwrapped interferogram. Produced using the ARIA Science Data System under development by JPL for the NISAR mission, using the ISCE software package. Contains modified Copernicus Sentinel data 2019, processed by ESA.
Sentinel-1 On-Demand InSAR Products

Qinghai, China Earthquake

Sentinel-1 On-Demand InSAR

Earthquake in Qinghai, China, January 2022. Sentinel-1 wrapped interferogram incorporating grayscale amplitude values. InSAR product processed by ASF DAAC HyP3 2022 using GAMMA software. Contains modified Copernicus Sentinel data 2022, processed by ESA.
Sentinel-1 On-Demand RTC Products
