Raw data from the Advanced Very High Resolution Radiometer (AVHRR) sensors on NOAA polar orbiting satellites, received at the Met Bureau's Darwin Satellite Reception Facility. These data are used later for computation of parameters such as sea surface temperature (SST). The data start from August 1992. The dataset contains approx. 4600 satellite passes as at Oct. 1998. The data are stored on Exabyte tapes in Hobart.
