title: Daily cycles in solar flux, snowmelt, transpiration, groundwater, and streamflow at Sagehen and Independence Creeks, Sierra Nevada, USA

description: Hydrometerological and ecohydrological time series from Sagehen Creek and Independence Creek, Sierra Nevada, USA, illustrating hydrological responses to daily cycles in snowmelt and evapotranspiration forcing.
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.
