Three new NCALM (National Center for Airborne Laser Mapping) datasets are now available from OpenTopography. Two of these datasets examine snow hydrology and dynamics in the western US. These include a dataset within the Sierra Nevada mountains near Truckee, California which was collected for Cara Piske at the University of Nevada, Reno to investigate forest-snow interactions in a high elevation critical zone. In addition, in March 2022, a dataset was collected east of Eugene, Oregon for Sarah Newcomb at Idaho State University. This dataset supports the investigation of the link between snowpack heterogeneity and subsurface storage and transmissivity in the rain-snow transition zone.
Finally, NCALM collected a dataset for Paula Figueiredo at North Carolina State University to examine the Mw 5.1 2020 earthquake in Sparta, North Carolina.
NCALM is an NSF-funded center that supports the use of airborne laser mapping technology (a.k.a. lidar) in the scientific community and is jointly operated by the Department of Civil & Environmental Engineering, Cullen College of Engineering, University of Houston and the Department of Earth and Planetary Science, University of California, Berkeley. OpenTopography is the primary distributor of NCALM data.
