Tahoe rain or snow precipitation phase observations

These data include observations of rain, snow, and mixed precipitation from the Tahoe Rain or Snow citizen science project. Included with each observation is a set of ancillary variables, including latitude and longitude, elevation, modeled meteorological data, and additional info. Please see the metadata file for the description and units of each data column.

Methods
Please see Jennings et al. (2023) and Arienzo et al. (2021) for full methodological details. In brief:

We collected observations of rain, snow, and mixed precipitation from community observers using the Citizen Science Tahoe mobile app
The app automatically timestamped and geolocated each observation
We associated each data point with elevation and modeled meteorological data, along with the percentage probability of liquid precipitation from the Integrated Multi-satellitE Retrievals for GPM (IMERG) Level 3 v. 6 product
We quality-controlled observations based on modeled air temperature, nearby precipitation, nearby relative humidity, distance from meteorological stations, and duplicate timestamps
