Due to a failure with the receiving station at the Institute of Geography the operational update of NOAA AVHRR quicklooks has been terminated. We regret to inform that we do not expect the service to become operational again but we are considering other alternatives.
For more information about the possible data products available from the Institute of Geography please contact Michael Schultz Rasmussen (msr@geogr.ku.dk)

An operational NOAA HRPT receiving station is maintained at the Institute of Geography. Full quality 1 km NOAA AVHRR data are received and the ordinary schedule is to archive all cloud-free scenes day or night. For specific purposes all possible NOAA passes can be received and archived (NOAA 12, 14, 15 and 16 night, morning, midday and evening).

(time indicated is UTC)
Data may be used for publications, in television transmissions etc. only if a clear reference to the Institute of Geography, University of Copenhagen is indicated.
An archive of processed AVHRR data is progressively being build, according to our scientific and teaching needs. Learn more about NOAA AVHRR data on: http://www.itc.nl/~bakker/noaa.html
The Institute of Geography is interested to collaborate with projects exploiting AVHRR data. The principles are that access to data is granted if scientific perspectives justifies it or if the ongoing processing of data can be supported in one way or the other. Contact msr@geogr.ku.dk
Image processing is done using the software WinChips including the special module "NOAA import". This NOAA module unpacks, calibrate and navigate AVHRR raw data according to the highest standards as defined by NOAA NESDIS. All major raw data formats are supported. Data are rectified using orbit data supplied as TLE or T-BUS data. Nominal accuracy is +/- 4 km, however, allowing an interactive shifting of a vector coastlinefile on top of the image, the accuracy is improved to less than +/- one pixel. WinChips supports ArcView shape files (vector files). The WinChips Scripting Language is used for the automatic operational processing of all received NOAA AVHRR data. The script unpacks and rectifies the data and subsequently generates JPEG quick-looks for future easy access to the database. Within 5 to 10 minutes after the image acquisition, the rectified data along with the JPEG files are available on a network server.

The receiving station is a Data Tools HRPT station, see: http://www.data-tools.com
