Polar Area Weather Station (PAWS) The Polar Area Weather Station (PAWS) is designed to be installed on an ice floe, measuring air and surface temperature, barometric pressure, relative humidity, as well as wind speed and direction at approx. 2m height. The platform reports GPS position and atmospheric data via iridium. Dummy photo Buoy description Manufacturer: MetOcean, Halifax, Canada Manufacturer‘s name: PAWS Data provider JouBeh Technologies, Halifax, Canada Weight approx. 65 kg Deployment type Installation on sea ice through 25 cm hole Technical Details Measured parameters Sensor Air and surface temp. (°C) YSI 44032 (accuracy ±0.1°C) Wind speed (m/s) RM Young #05103AP anemometer (accuracy ±0.3 m/s) Wind direction (deg) RM Young #05103AP anemometer and PNI TCM2.5 compass (accuracy ±3 deg) Relative humidity (%RH) HMP155 (Vaisala) (accuracy: ±3 %RH) Barometric pressure (hPa) PTB110 (Vaisala) (accuracy: ±1 hPa) or equivalent GPS position Jupiter 32 (Navman) (accuracy: ±2.5 m) Measurement interval MET data hourly, GPS updated every 3h Data transmission Hourly transmit Data transmitter Iridium 9602 SBD transceiver Power supply Lithium batteries (life time >1 year)
