Agriculture / Drought
The yield prognosis based on vegetation indices derived from satellite data from NOAA/AVHRR and TERRA/MODIS satellites are made by our specialists.
In the Remote Sensing Centre crop growth conditions are monitored with the use of models based on NOAA/AVHRR satellite data. Condition of vegetation is presented for agricultural areas spatially.
For determining areas threaneted with drought index of identification of agricultural drought - DISS is applied. The index is strictly related to rainfall and air temperature since start of vegetation season. Models are based on radiation temperature derived for each 1 sq. km area (NOAA pixel) and for every 10-day period within vegetation season. Using satellite indices, which characterize plant phenology and their water requirements in particular phases of crop development, drought intensity and its impact on yield reduction is determined. The monitoring is conducted since autumn sowing through spring crop development till harvest.
