Abstract:

The Polar Automatic Weather Station PAWS was developed to meet a need for detailed weather data from polar regions. It telemeters windspeed and direction 1-min averages, barometric pressure, and air temperature via a high-frequency radio link when interrogated by a central station. The accuracy of the telemetered data is as follows windspeed, or - 1 n.mih wind direction, or - 5 deg barometric pressure, or - 1 mbar air temperature, or - 1 F 0.55 C. The PAWS has a radioisotope power generator that can supply power for at least 5 years of unattended operation. A detailed description of the equipment, its operation, and the results of field trials is presented. Recommendations are presented for eliminating the problems encountered during field trials.
