NASA MEaSUREs Research Project: EASE-Grid 2.0 TB ESDR
The NASA MEaSUREs Research Project: EASE-Grid 2.0 TB ESDR produces improved, enhanced-resolution, gridded passive microwave ESDRs for monitoring cryospheric and hydrologic time series. The data our project produces are available from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
Explore our latest news and events, including white papers, data updates, publications, and presentations from along the course of this project.
New white paper available
October 2021: Brightness Temperature Comparison of Enhanced Resolution SSMIS Images Created from CSU ICDR V1 and GPM L1C V5 Files
This recent project white paper compares CETB images derived from alternative near real-time sources.
Version 2 enhanced-resolution SMAP TBs available at NSIDC DAAC
August 2021: Using the latest reprocessed L1B SMAP TBs, we have reprocessed the complete SMAP Enhanced Resolution CETB data, available from the NSIDC DAAC. More information here:
We are also using the latest SMAP L1B inputs to produce near real-time SMAP CETB images, available by request from Mary Jo Brodzik.

Endorse the Joint Declaration of Data Citation Principles
One of our goals in producing a new Earth Science Data Record is to contribute a systematic, reliable data set for use in scholarly research. When researchers use our data set in scholarly publications, we encourage the good practice of proper data citation. Please consider endorsing the Joint Declaration of Data Citation Principles, and committing to adopting these guidelines in your own publications that rely on scientific data sets.
Early adopters needed
When we make prototype products available in summer 2015, would you be willing to evaluate them and provide us feedback, as a potential early adopter of the data? If so, please contact Mary Jo Brodzik.
