Remote sensing

Since 1990 the BSH has been receiving and processing AVHRR-data from the polar orbiter NOAA-satellites and since september 2009 from the europian weather satellite MetOp by EUMETCast too and generates marine products in daily routine . Several times a day, the satellites transmit images of the Earth's surface in the visible and thermal infrared spectral ranges. By using adjusted processing techniques the BSH produces charts of ice distribution and sea surface temperature (SST). To eliminate cloud covered areas as far as possible we generate our charts composing several weather satellite passes.
We make charts of other condition parameters (chlorophyll, yellow substances, suspended matter, transparency) as well. Brockmann Consult GmbH delivers the data we use, based on measurements of the MERIS-sensor onboard the ENVISAT-satellite.The environmental satellite ENVISAT which is operated by the European Space Agency (ESA) provides earth observation data using different optical and radar sensors.
