Any two of the six available AVHRR channels can be chosen by ground command for processing and ultimate output Smoothened inhibitor to the APT transmitter. The analogue APT signal is transmitted continuously

and can be received in real time by relatively unsophisticated, inexpensive ground station equipment AVHRR The Advanced Very High Resolution Radiometer is a broad-band, four, five or six channel (depending on the model) scanner, sensing in the visible, nearinfrared, and thermal infrared portions of the electromagnetic spectrum. This sensor is carried on the National Oceanic and Atmospheric Administration’s (NOAA’s) Polar Orbiting Environmental Satellites (POES), beginning with TIROS-N in 1978 AVHRR/NOAA AVHRR working on board a Tiros-N/NOAA series spacecraft (satellite). AVHRR (NOAA 14) – AVHRR working on board the NOAA 14 satellite BALTFOS BALTic FOrecasting System BOOS Baltic Operational Oceanographic System CICE The Los Alamos sea ice model. ‘CICE‘ – an acronym, for ‘Community Ice CodE’. The acronym is pronounced ‘sea ice’ 3DCEMBS

3 Dimensional Coupled Ecosystem Model of the Baltic Sea DESAMBEM Complex satellite algorithm for the Baltic, also known as the DESAMBEM Diagnostic System (abbreviation taken from AC220 concentration the name of previous project No. PBZ-KBN 056/P04/2001) ‘The Development of a Satellite Method for Baltic Ecosystem Monitoring’ DMSP Defense Meteorological Satellites Program (DMSP) – a series of spacecraft to investigate the Earth’s environment from an altitude of ~ 800 km. They were all put into Sun-synchronous near-polar orbits (inclination ~99 degrees). Of interest to the high- energy science community are DMSP F10, F11, F12, F13, F14, F15, F16, F17 and F18 EcoSat A new model (EcoSat)

enabling the assimilation of remotely determined distributions of surface chlorophyll a concentration ENVISAT ENVISAT (ENVironmental SATellite) – the largest Earth Observation spacecraft ever built. It carries ten sophisticated optical and radar instruments to provide continuous observation Tyrosine-protein kinase BLK and monitoring of the Earth’s land, atmosphere, oceans and ice caps. Launched in 2002 EOS/AQUA Aqua is a NASA Earth Science satellite mission named for the large amount of information that the mission will be collecting about the Earth’s water cycle. The Aqua mission is a part of the NASA-centered international Earth Observing System (EOS) GMES Global Monitoring for Environment and Security – the European Programme for the establishment of a European capacity for Earth Observation HRPT The High Resolution Picture Transmission (HRPT) system provides data from all spacecraft instruments at a rate of 665.400 bps. The S-band realtime transmission consists of the digitized unprocessed output of five AVHRR/3 channels, plus the TIP (HIRS/3 for NOAA KLM and HIRS/4 on NOAA-N, -P, SBUV/2, SEM, DCS/2) data and AMSU data.
