Temperature, Humidity, and Time-Lapse Video Data from Yosemite National Park, Water Year 2024

This dataset contains timelapse videos and distributed measurements of air temperature, relative humidity, dewpoint, and soil temperature across Yosemite National Park from October 2023 to September 2024. Instruments were deployed across 10 sites in two cross-valley transects as part of the DOE Grant: Seasonal Cycles Unravel Mysteries of Missing Mountain Water organized by lead-PI Dr. Jessica Lundquist (University of Washington), and co-PIs Dr. Rosemary Carroll (Desert Research Institute) and Dr. Ethan Gutmann (National Center for Atmospheric Research). This project will use these surface data in hydrologic models to better resolve the fate of mountain water. Data are made available for other projects interested in surface climate or hydrologic processes in complex terrain. Measurements are taken with low-cost data loggers strapped to trees or buried just below the soil surface. The timelapse video captures images 3x daily images across one transect and provides insight into valley-scale seasonal snow cover variability. Files contained in this dataset are named and organized by site and variable type (air measurements, ground measurements, or timelapse video). Air and ground measurements are packaged in LoggerData.zip, and the timelapse video is stored in TimelapseVideos.zip. File-level metadata contains details for each file included in the dataset. A data dictionary provides units and descriptions for column or row names in all files. Locations metadata describes site characteristics, locations, and associated GPS methods.
