Version Summary

Extended F/T record to 2017;

F/T domain expanded to all land areas affected by seasonal freezing, including urban, snow-ice dominant, open water body dominant, and barren land;

Added a modified seasonal threshold algorithm (MSTA) and pixel-wise, annual MSTA calibration using daily surface air temperature records;

Added bit flags to identify cells (and days) with missing/interpolated Tb, large open water bodies, complex terrain, and large precipitation events;

Overview

This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of two global records of the daily freeze/thaw (F/T) status of the landscape. The primary record is derived from radiometric brightness temperatures acquired between 1979 and 2017 by three satellite-based passive microwave sensors: the Scanning Multichannel Microwave Radiometer (SMMR), the Special Sensor Microwave/Imager (SSM/I), and the Special Sensor Microwave Imager/Sounder (SSMIS). A second, synergistic record is available for the years 2002 to 2017, derived from observations acquired by the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) and the Advanced Microwave Scanning Radiometer 2 (AMSR2).

Filter and order from a data set web page using the Data Access Tool

Many NSIDC DAAC data sets can be accessed using the NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.Users have the option to

The NSIDC Data Map Services Application Programming Interface (API) provides HTTP URLs for requesting geo-registered map images from NSIDC's geospatial database. A WMS request defines the geographic layer(s) and area of interest to be processed.

We recommend using the Geospatial Data Abstraction Library (GDAL) to convert GeoTIFF files into a different format.

To convert HDF5 files into binary format you will need to use the h5dump utility, which is part of the HDF5 distribution available from the HDF Group. How you install HDF5 depends on your operating system.

Programmatic Data Access Guide

All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is directly accessible through our HTTPS file system using Wget or curl. This article provides basic command line instructions for accessing data using this method.

NASA Worldview is a map interface that allows users to interactively browse imagery, create visualizations, and download the underlying data.
