    "abstract": "The WeatherPak monitoring system supplied by Coastal Environmental Systems is a shipboard weather station designed for harsh environments. Using built in GPS and a compass it is able to calculate true winds (accuracy: +/- 0.3 m/s, resolution: 0.1 m/s) and winds relative to ship motion. It includes meteorological sensors for pressure (+/- 0.2 hPa @ 25°C, 1 hPa), temperature (resolution: 0.2°C), relative humidity (resolution: 1%), pitch, heave and roll. Data is transmitted via ship NMEA system. Data can be recorded up to 1 second time resolution.",
