NASA MEaSUREs Research Project: EASE-Grid 2.0 TB ESDR

An improved, enhanced-resolution, gridded passive microwave ESDR for monitoring cryospheric and hydrologic time series

What's New

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.

2021


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.


New papers published 

May 2021: See recent TGARS paper investigating band-limited signal reconstruction using SMAP data:

and new NSIDC Technical Reports estimating effective resolution enhancement using actual CETB data:


2019


Enhanced-resolution SMAP TBs delivered to NSIDC DAAC

July 2019: We have used the rSIR algorithm to produce enhanced-resolution SMAP radiometer brightness temperatures as a companion data set to the CETB v1.3 data, available from the NSIDC DAAC. More information here:


2018


Complete CETB v1.3 delivered to NSIDC DAAC

April 2018: We have completed submission of the entire SMMR, SSM/I-SSMIS and AMSR-E collection of CETB v1.3 data to the NSIDC DAAC, more information here:

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.
