The simultaneous heat and water (SHAW) model explicitly describes the water and heat transfer in canopy, snow, residue and soil. Many studies have indicated that the SHAW model can correctly simulate the water and heat dynamics of freeze/thaw regions (Guo et al. 2011a, b; Zhou et al. 2008). Visa mer The A’rou freeze/thaw site (E 100°27, N 38°02, 3,032 m) is located in the eastern part of the Tibet-Qinghai Plateau. The land cover type is alpine meadow, and seasonally frozen soil is common throughout the region. … Visa mer The SHAW model requires surface parameters (e.g. LAI, plant dry weight and plant height) to predict the heat and water transfer. The soil temperature and soil water contents … Visa mer Data quality control processes were applied to raw 10 Hz EC data to obtain half-hourly flux data (Zhang et al. 2010). The processing steps included despiking, coordinate rotation, … Visa mer Biome-BGC (White et al. 1997; Thornton and Running 2002; Thornton et al. 2002) was developed based on the Forest-BGC model.
