The British Antarctic Survey has collected an important and long-term series of Advanced Very High Resolution Radiometer (AVHRR) data at Rothera research station covering the Southern Ocean, Antarctic Peninsula and coast of West Antarctica, from February 1993 to date. These data are valuable in studies of climate change, the effect of sea-surface temperature (SST) variability on Southern Ocean ecosystems, iceberg tracking and weather systems, but previously were not easily available to the UK environmental science community.
This project has transferred a copy of the archive to the NERC Earth Observation Data Acquisition and Analysis Service (NEODAAS), where existing systems have been extended to generate a complete scientific data set of polar products at full 1.1 km spatial resolution. Products include SST, brightness temperature, visible reflectance and cloud mask.
All raw and processed data have been catalogued using standards-compliant metadata for searching at the NERC Earth Observation Data Centre website: this assists access via the NERC DataGrid.
ARIES (Antarctic Reception of Imagery for Environmental Studies) is based on a receiver for the NOAA High Resolution Picture Transmission (HRPT) data stream from the NOAA series of polar orbiting weather satellites.
