Abstract

The drought affects agricultural crops by diminishing amount of water necessary for vegetation. Deficit of soil moisture in specific vegetation growth stage causes the reduction in crop yield. The research, which has been carried out in Poland, gives consistent information on soil and vegetation growth over agricultural regions using various satellite-derived soil - vegetation indices. A wide range of ground-based measurements such as soil moisture, leaf area, and biomass were collected on nearly same dates of satellite overpass. The different soil moisture indices have been calculated on the basis of evapotranspiration derived from the surface temperature obtained from NOAA/AVHRR and meteorological data. The temperature condition index (TCI) characterising the status of crop development has been obtained from Global Area Coverage (GAC) data derived from NOAA images. Furthermore, latent heat fluxes and NDVI values have been calculated and implemented as the input to the models. This paper describes the analysis and results of a study to improve the detection and monitoring of drought conditions.
