Frozen winter cereals
Observations of areas with frozen winter cereals are made at the Department of Remote Sensing. There are applied optical images registered from satellites NOAA, Terra and WorldView-2.
Terra.MODIS data are used to snow coverage and surface temperature observations. MODIS data are registered at 250-meter pixel resolution. They are ancillary data for correct recognize of areas where frozen winter cereals occured.
The maps of areas with frozen winter cereals in 2012 were performed applying NOAA.AVHRR images too.
In relating to CSO assessments the greatest losses ot winter cereals were observed in the followed voivodeships: Kujawsko-pomorskie, Lubuskie, Lubelskie, Łódzkie and Wielkopolskie.

In addition WorldView-2 image were applied to analyzing frozen plants within crop parcels. WorldView-2 scenes are registered at 0.46-meter in panchromatic band and at 1.84-meter in eight spectral bands.
