Snow depth, air temperature, humidity, soil moisture and temperature, and solar radiation data from the basin-scale wireless-sensor network in American River Hydrologic Observatory (ARHO)

Snow depth, air temperature, humidity, soil moisture and temperature, and solar radiation are measured by a basin-scale wireless-sensor network in the American River Hydrologic Observatory (ARHO). The wireless-sensor network is deployed across the upper, snow-covered areas of the American River basin from 1510 to 2723 m elevation on the western slope of the Sierra Nevada in California. The network comprises 13 sensor clusters (Schneiders, Echo Peak, MT Lincoln, Caples Lake, Alpha, Duncan Peak, Van Vleck, Dolly Rice, Onion Creek, Robbs Saddle, Talbot Camp, Owens Camp, Bear Trap) at different elevations. Each cluster comprises 10 wirelessly connected sensor nodes strategically placed with distinct elevation, canopy cover, slope, and aspect within a 1 km2 area. These 130 spatially distributed sensor nodes measure snow depth, air temperature, relative humidity, soil moisture and temperature, and solar radiation at 15-minute intervals. Raw data (level 0) have been processed to level 1 (QA/QC...
