Amount of usable water in loam soils in Czech Republic
2014-07-09
creation
CZ-CHMU-ZVVP_AKT
Amount of usable water in loam soils with available water capacity 170 mm for 1 m deep soil profile under grassland in the Czech Republic, the current status for any given Sunday. Processing in a weekly step (on Tuesday)from daily values of usable water supplies in the soil modeled by model AVISO (CHMI, Brno branch) for 198 automatic meteorological stations CHMI station network. Presented as one of the outcomes of drought monitoring in the warm half of the year in section soil drought on a publicly accessible website CHMI.

Amount of usable water in loam soils under grassland modeled in daily step for 198 automatic stations is one of the outputs of the agro-climatic model AVISO (CHMI, Brno branch). Calculation is done for loam soil with available water capacity of 170 mm and 1 m deep soil profile. Results are given in % of available water capacity. The input data for the calculation are obtained from the CLIDATA database. Spatial interpolation of point values is performed automatically using linear regression method related to altitude with correction of estimated values using the residuals to preserve the measured values at stations (the method is part of CLIDATA). The resulting raster dataset has a spatial resolution of 500 m and is processed in the ArcGIS environment and generalised using Focal Filter method. The whole process runs semi-automatically using Python scripts. The map is placed on the CHMI portal in JPEG format.
