SDC Project: RAMPPost RAMP Products

Subsequent to the 1997 and 2000 Antarctic Mapping Missions, two other smaller mappings were made in 2004 and again in 2007. Velocity products were generated for the Drygalsky Ice Tongue (David Glacier) and the Thwaites and Pine Island Glaciers.

Interferometric pairs are used to compute ice sheet surface velocities during the approximate months of September through December. The methodology and results discussed in this report are provided in partial fulfillment of OSU's agreement to provide remote sensing data to the Center for Remote Sensing of Ice Sheets (CReSIS) CRESIS Home Page science requirements. CReSIS's vision is to advance understanding of polar ice sheets sufficiently for the development of models that reliably predict future ice sheet contributions to sea level rise under prescribed changes in climate.

Documentation and procedures used to process Radarsat synthetic aperture radar data were the same used to obtain velocities in for Jacobshavn Glacier, Greenland Document Page

We have provide the following datasets.

Velocity ASCII files containing the final derived velocities
SAR mosaics (100m) in binary, geotif, and ERDAS Imagine formats
RAMS Final Velocity Products (the individual pieces that went into making the derived ASCII version)
