NASA Data Records
Sea-ice imagery and data products are supported under NASA's Making Earth System data records for Use in Research Environments (MEaSUREs) program. These data have been used in a variety of applications.
- More than 11 years of RADARSAT-1, nearly uninterrupted, three-day radar snapshots of Arctic Ocean sea ice.
- Original synthetic aperture radar (SAR) images.
RADARSAT-1 data have been processed to
- Construct a near decadal record of small-scale ice motion of the Arctic Ocean.
- Produce a record of ice motion of the northern Bering Sea.
- Assemble monthly high-resolution image mosaics of the Arctic Ocean.
These datasets are available from the ASF DAAC and NASA's Jet Propulsion Laboratory (JPL) through the project’s principal investigator, Ron Kwok. The original RADARSAT-1 images used to generate the products are available for download at no cost from the Alaska Satellite Facility datapool to approved users. To become an approved user, please submit the required Research Agreement.
MEaSUREs supports the NASA Earth-science research community in providing Earth science data products and services driven by NASA’s Earth-science goals. MEaSUREs projects focus on the creation of Earth System Data Records (ESDRs), including Climate Data Records. An ESDR is a unified and coherent set of observations of a given parameter of the Earth system that is optimized to meet specific requirements in addressing science questions.
These records are critical to understanding Earth system processes; assessing variability, long-term trends, and change in the Earth system; and providing input and validation means for modeling efforts.
