CReSIS Radar Data Products

Click here for acknowledgements, citing, and reporting data usage.

Click here for education and materials for the general public.

All CReSIS radar data products that are available for distribution are located here and at NSIDC. The radar data products are:

We also make several tools available for download:

If you are having trouble finding your data with the Matlab Geographic Search tool (e.g. you don’t have access to Matlab), please send us your corner coordinates and we will run it for you.

If you want a large amount of data, please send us a hard drive (internal 2.5” or 3.5” SATA) or USB flash drive and we will transfer the data that you need. In most cases you will need to set up prepaid return shipping or an equivalent.

Please direct questions, suggestions, and error notifications to cresis_data@cresis.ku.edu

Geographic Search and Download Tools

There is an online tool that allows geographic searches from a web browser at our Polargrid project site. This tool is useful for looking at single frames of data at a time and only displays radar depth sounder data. Go to the following link and select Antarctica Data Browser or Greenland Data Browser.

http://polargrid.org/polargrid/software-release

There are two Matlab tools for doing geographic searches for any of the radars. For the radar depth sounder, they both can optionally download the L2 data in your region of interest. The first tool is geographic_search.m and is a basic console script which allows a corner coordinate search in latitude/longitude. The second tool is geographic_search_gui.m which includes a graphical user interface (GUI), but requires the mapping toolbox (type "ver" in Matlab to be sure you have it); the second tool is run using run_geographic_search_gui.m. It returns all points within a polygon which is drawn by the user using the GUI. A snapshot of the GUI for drawing the polygon is here. The tools are located here:

Matlab Image Browser and Layer Picker

This is a set of Matlab code which loads data and allows it to be browsed geographically and to pick layers in echograms (currently only two layers are supported).

MAT File Readers for IDL and C

IDL and C functions for loading 1 or 2 dimensional matrices from MAT files. Complex data structures such as cell arrays and structures are not supported by the reader, but the data products’ primary fields of interest are all 1 or 2 dimensional matrices. ftp://data.cresis.ku.edu/data/mat_reader/
