Dear UNAVCO Colleagues;

We are pleased to announce the release of an updated 2019 lidar dataset, collected by the National Center for Airborne Laser Mapping (NCALM) and funded by the U.S. Geological Survey (USGS) and the U.S. National Science Foundation (NSF EAR-1945781 & EAR-1945754), covering 784 square kilometers of the region impacted by the 2019 Ridgecrest earthquake sequence in southern California.  This new release adds data over Naval Air Weapons Station China Lake, and now covers the main surface fault ruptures of both the M 6.4 and M 7.1 Ridgecrest earthquake sequence. In addition, all data have now been classified by NCALM, meaning that points are now identified as either having hit the ground or vegetation, etc.

Here is the link to the announcement, including slider images and a sample KMZ file:

Please let me know if you have any questions or would like a reprint of our team's SRL paper.*

Many thanks to all co-authors and everyone else involved in making this possible.

Sincerely,

     Ken
