WATER: Dataset of precipitation and canopy interception observations around the Dayekou Guantan forest station

The dataset of precipitation and canopy interception observations was obtained around the Dayekou Guantan forest station (100m×100m, pure Qinghai spruce) from Jun. 1 to Oct. 10, 2008. Observations were carried out immediately after each rainfall. The following instruments have been used for the observation: the rain gauges (diameter: 20cm; 2 for controlled rainfall and 20 for throughfall), self-ma...

WATER: Dataset of snow spectral reflectance observations in the Binggou watershed foci experimental area from Dec. 5 to Dec. 15, 2007 during the pre-observation period

The dataset of snow spectral reflectance observations was obtained in the Binggou watershed foci experimental area from Dec. 5 to Dec. 15, 2007 during the pre-observation period. The aims of the measurements were to verify feasibility of the predetermined observation schemes and to collect data for retrieval from remote sensing approaches. All data were acquired by ASD spectrometer from Xinjiang M...
