Zoom In: Geolocating IceBridge Data

In 2009, NASA initiated Operation IceBridge, flying airborne missions to pinch hit for the ICESat satellites’ expected gap from 2009 to 2016. The airborne platform and the broad suite of instrumentation allow for the collection of high resolution snow and ice data from targeted areas of scientific interest. The downside is that the total area covered is not nearly as vast as what a satellite typically covers.

The resources listed below allow you to zoom in on the specific areas of the Earth where IceBridge data were collected. Many of these resources also provide a handy way to access the IceBridge data of your choice.

IceBridge Data Portal

* See flight lines plotted against imagery, DEM or ice velocity layers

* Zoom to your area of interest to find and download data from flights that intersect your target area

ATM Flight Lines in Google Earth

KML flight lines provided by the ATM instrument team

* Download simplified flight lines and view them in Google Earth or your favorite Earth browser

* Note: While these represent the majority of IceBridge flights, they will not include campaigns flown without the ATM instrument

Earthdata Search

The new Earthdata Search

 

NASA Reverb or the new Earthdata Search tool

* See the locations of flight segments associated with each data file on a map

* Search for and download just the data files that meet your criteria

* Note: Many but not all IceBridge data sets are available for visualization and download with these tools

Geolocation coordinates in the data files

* Those who have already selected and downloaded data files may start analyzing the individual measurements based on the Latitude and Longitude coordinates contained therein

* To the right is an example of a data table taken from the IceBridge MCoRDS L2 Ice Thickness data set

Instrument position data

* Some researchers may need instrument position information, which may include altitude, velocity, roll, and pitch in addition to coordinates

* Separate data sets with this information are available for the DMS Camera and the LVIS Instrument

* For some other instruments, this information is included within the Level 0 data set for the instrument. To easily browse the holdings of IceBridge data sets, see the NSIDC Data Search tool
