We are planning a complete reprocessing of the existing passive microwave brightness temperature record, to produce a new, multi-sensor Level 3 ESDR that incorporates SMMR, SSM/I-SSMIS, and AMSR-E, with recently released improvements in sensor calibrations, as well as improvements in cross-sensor calibration and quality checking, modern file formats, better quality control, improved projection grids, and local time-of-day processing.
The new ESDR will be gridded to the EASE-Grid 2.0 format. It will include conventional resolution products as well as enhanced-resolution imagery. We are expecting that the new ESDR will better serve the large community of land surface and polar snow/ice researchers that currently uses Level 3 passive microwave data in long-term climate studies with better data usability and reliability.
We are planning to solicit community feedback on a prototype ESDR that we will release by the summer of 2015. We will welcome feedback and comments on the new ESDR. If you are interested in evaluating the prototype products, please contact Mary Jo Brodzik.
The final products will be available at the NSIDC DAAC by the summer of 2017.
