The ASO L4 Lidar Snow Depth 3m UTM Grid, Version 1; ASO L4 Lidar Snow Depth 50m UTM Grid, Version 1; and ASO L4 Lidar Snow Water Equivalent 50m UTM Grid, Version 1 data sets, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated to include new data for 2019. In addition, data for 8 new basins were also added. These data sets contain gridded snow depth data at 3-meter and 50-meter resolutions derived from airborne light detection and ranging (lidar) measurements of surface elevations, and gridded snow water equivalent at 50-meter resolution derived from the 50-meter snow depth data set. The data were collected as part of the NASA/JPL Airborne Snow Observatory (ASO) aircraft survey campaigns.

The ASO L4 Lidar Snow Water Equivalent 50m UTM Grid data set has been updated from a basic to a standard level of service at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).  This means a higher level of support is available for data-usage questions, guidance on the use of the data with select analysis tools, and a user guide is now available.  Please see our “Adding clarity to NSIDC data support with new Level of Service (LoS) model” article for more information.

This data set contains 50 m gridded snow water equivalent (SWE) values collected as part of the NASA/JPL Airborne Snow Observatory (ASO) aircraft survey campaigns.  The available temporal coverage has been updated to include data from 8 February 2016 to 2 June 2018.

The ASO L4 Lidar Snow Depth 50m UTM Grid data set has been updated at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) to include data from 8 February 2016 to 2 June 2018.

This data set contains 50 m gridded snow depths derived from airborne light detection and ranging, or lidar, measurements of surface elevations. The data were collected as part of the NASA/JPL Airborne Snow Observatory (ASO) aircraft survey campaigns.

The ASO L4 Lidar Snow Water Equivalent 50m UTM Grid data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) from 08 February 2016 to 08 July 2016. This data set contains 50 m gridded snow water equivalent (SWE) values collected as part of the NASA/JPL Airborne Snow Observatory (ASO) aircraft survey campaigns. The data were derived from the ASO L4 Lidar Snow Depth 50m UTM Grid data product and from modeled snow density.

This data set is available as part of an early release. Minimal documentation is currently available. An increased Level of Service and more detailed documentation will be available in the future.
