Analysis of snow coverage

Analysis of snow coverage in country or regional scale is the important element needed for evaluation of crop development conditions. Range and period of covering agricultural areas with snow implies conditions of surviving winter cereals through winter time, as well as it determines water capacity of soils at the beginning of growing season, influencing acceleration or delay in crop development.

Low-resolution satellite images NOAA.AVHRR, Terra.MODIS, SPOT-VEGETATION, operationally acquired by IGiK’s Remote Sensing Centre, enable to monitor snow cover in Poland, allowing to conduct analyses aimed at assessment of crop quality at the start of growing period. Analyzing of snow cover is also applied for observations of areas with frozen winter cereals.

Terra.MODIS images registered from November to April of every year are applied for monitoring of snow coverage.

Snow observations derived from SPOT-VEGETATION are presented below.
