Search and discover NSIDC data sets with our new search tool

How do I differentiate between sea ice data sets? Which ones have file formats that are easy for me to use? How many ice velocity data sets are offered at NSIDC? What are my options for downloading the data? NSIDC has been busily working to develop a Web tool to answer these questions and more. The new Scientific Data Search aims to help you discover the data sets most useful to you.

Scientific Data Search interface

This new tool replaces the previous NSIDC data set search tool. It is recommended for those who would like to explore the breadth of NSIDC’s data holdings.

Using the search tool’s interface, you can find which data sets contain a particular data parameter, such as snow cover, or which data sets were submitted by a specific Principal Investigator. Map and calendar controls also allow you to see which data sets intersect with your custom spatial area or temporal range.

The listing of results is designed to allow for quick scanning. Attributes are clearly displayed to facilitate selection. You can read more about a data set in your results list by clicking on the title, or you can click the ‘Get Data’ button if you are ready to download the data.

The ‘Get Data’ button expands to show you all the various alternatives for downloading or visualizing the data. Those of you who are familiar with the data offerings may appreciate the direct link to the FTP directory. Those who are looking for ways to subset the data will find direct access to tools such as the Reverb and Polaris data order interfaces.

Future enhancements to the search tool will allow for results to be narrowed by custom inputs and will allow for better comparison between similar data sets.

Please give the Scientific Data Search a try. We welcome your comments at nsidc@nsidc.org.

Hello to new services in Reverb|ECHO; Goodbye to Data Pool search and order

New services that can be applied to AMSR-E and MODIS data have recently been added to the Reverb search and order tool. NASA Reverb|ECHO and NSIDC recently implemented these services in preparation for the decommissioning of the Data Pool search and order interface. Service options include reformatting the data from HDF-EOS to GeoTIFF, reprojection, and spatial or parameter subsetting. We created a tutorial to help data users access these data services.

The Data Pool search and order interface will be decommissioned on 28 August 2013. If you used the Data Pool search and order interface to reformat, reproject, or subset data, please use the new data services in Reverb. The Data Pool FTP site that provides direct access to data granules will remain available after the Data Pool search and order interface is decommissioned.

Recent enhancements to the NASA IceBridge Data Portal

The NASA IceBridge Project is comprised of airborne data over the most dynamic areas of the Arctic, Greenland, Alaska and Antarctica. The data gathered by this project are unique in that they are spatially referenced by flight lines, flights are flown during approximately 3-month campaigns, and data are collected by a wide variety of instrumentation.

The NASA IceBridge Data Portal provides a single location from which one can get an overview of all the IceBridge data sets. It allows for map-based visualization of the flight paths via polar views of the Northern and Southern Hemispheres.  Using a variety of filters and image overlays, one can visualize, search and download IceBridge data campaigns. NSIDC recently added some new capabilities to the IceBridge Data Portal. These new features include:

- A simpler display which allows users to hide and move informational windows

- The ability to filter results by selecting one or more instruments

- A tar-on-the-fly option for downloading complete directories of data at once

- New map layers for enhanced visualization including:

  • Mosaic of Greenland (MOG)
  • Shaded Relief DEM
  • MEaSUREs Velocity Map
  • Mosaic of Antarctica (MOA)
  • Antarctic Bedrock DEM
  • Radarsat Antarctic Mapping Project (RAMP)

Begin your search for IceBridge data through the newly improved NASA IceBridge Data Portal.
