1. Satellite observations

Global system of weather satellites; geostationary satellites; Low-Earth polar orbiting satellites. EUMETSAT organization and its prime satellites (MSG, MTG, Metop, Metop-SG). European Space Agency (ESA); other European space-related activities and programs. Third party weather satellites and programs – NOAA/JPSS, GOES, and other. Principles and basics of data acquisition and primary data processing; data and products distribution to end users. Spectral bands and their basic characteristics, atmospheric spectral windows. Solar radiance, thermal emission. Reflectivity, transparency, emissivity, brightness temperature. Spectral bands (channels) of various weather satellite instruments. Basic spectral properties of clouds and land; principles of multispectral interpretation of weather satellite data. Basic methods of satellite data and image processing. Advanced image products – color image enhancement, RGB composite images, “sandwich” blended image products, basics of their interpretation. CHMI satellite system – data acquisition, processing, distribution and archive. Software (freeware) for processing and visualization of weather satellite data; data sources and their formats.

2.Radar measurements
