Data include 30-minute time series of - weather variables, - sap flow fluxes, - groundwater levels (in two riparian transects of shallow groundwater wells), - and stream stages (at 12 sites spanning a 500-meter elevation gradient), and daily time series of - temperature, precipitation, and snow water equivalent at three nearby snow telemetry stations - diel cycle index values for groundwater levels and stream stages, - and MODIS normalized difference snow index (NDSI) and enhanced vegetation index (EVI2) values averaged over selected subcatchments. Google Earth Engine scripts for extracting the MODIS data are also provided.
