Programs

We have developed several programs that may be used for hydro-meteorological studies. You may download them for non-commercial purposes.

A Temperature Prediction-Correction Method for Estimating Surface Soil Heat Flux from Soil Temperature and Moisture Data

This program calculates soil heat flux from soil moisture and temperature profiles.

Demo for Upscaling in-situ Soil Moisture Based on MODIS-derived Apparent Thermal Inertia (ATI)

The whole upscaling algorithm is composed of three steps. First, a functional relationship between the station-averaged soil moisture and the pixel-averaged ATI is constructed. Second, this relationship is used to calculate the representative soil moisture time series at a certain spatial scale. Last, the Bayesian linear regression is applied to obtain the upscaled area-averaged soil moisture by using in-situ measurements as independent variables. The algorithm is validated using a network of in-situ moisture sensors in the central Tibetan Plateau. This demo is used to illustrate the last step and validation.
