Sinclair, A. E., West, A. J, Clark, M. K., Horton, D. E. (2024). Uncertainty in Precipitation Observations, Hindcasts, and Forecasts over Southern California for Post-Tropical Storm Hilary. Establishing Directions in Postfire Debris Flow Science Conference. Lake Tahoe.

Geospatial data and observations were collected by the CLaSH team related to 2023 Tropical Storm Hilary in Southern California in collaboration with the NSF RAPID facility (University of Washington) and the NSF NCALM Lidar facility (University of Houston). The data collected are from two regions: 1) Death Valley and (2) the San Bernardino Mountains, specifically around Yucaipa Ridge. The data from this project were collected with the intention of capturing perishable information in the aftermath of this storm.

These data are being made freely and openly available for use by any interested parties, including academic and government researchers as well as others. Potential uses could include (but are not limited to) change detection, as well as evaluation of material properties in aid of mechanistic understanding and model parameterization, including quantification of grain size of sedimentary deposits. The data collected during this project also provide a baseline that can be used to evaluate future changes associated with land surface hazards at the studied locations. A map of the locations studied is available on the HazMapper site: https://hazmapper.tacc.utexas.edu/hazmapper/project-public/1171f732-5fc6-4c94-b7ac-d6aa6a36e199.

Database submissions to NSF repositories OpenTopography and DesignSafe are forthcoming and will be publicly available within the next few weeks and linked here.
