Version Summary
The data for 2009 through 2015 are stored in Version 1 of this data set.

Version 2 of this data set contains more parameters than Version 1. In addition, some parameters were renamed or removed. Essentially, Version 2 comprises the following changes:


  • LVIS_LFID is now called LFID.

  • LONGITUDE_LOW, LATITUDE_LOW, and ELEVATION_LOW were renamed to GLON, GLAT, and ZG.

  • LONGITUDE_HIGH, LATITUDE_HIGH, and ELEVATION_HIGH were renamed to HLON, HLAT, and ZH.

  • LONGITUDE_CENTROID, LATITUDE_CENTROID, and ELEVATION_CENTROID were removed.

  • TLON, TLAT, and ZT were added.

  • RH10 through RH100 were added.

  • AZIMUTH, INCIDENTANGLE, RANGE, and COMPLEXITY were added.

  • CHANNEL_ZT, CHANNEL_ZG, and CHANNEL_RH were added.

Overview

This data set contains surface elevation data over parts of Greenland, measured by the NASA Land, Vegetation, and Ice Sensor (LVIS), an airborne lidar scanning laser altimeter. The data were collected as part of NASA Operation IceBridge funded campaigns.

How To

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.
This guide will provide an overview of the altimetry measurements and data sets across the missions, as well as a guide for accessing the data through NASA Earthdata Search and programmatically using an Application Programming Interface (API).
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) can be accessed directly from our HTTPS file system, using wget or curl. Basic command line instructions are provided in the article below.
