Methods: 

The meteorological station on the surface of Lake E5 was initially installed in the spring of 2000. The station records air temperature, relative humidity, wind speed, and wind direction. Measurements are taken at a 30 second interval, averaged every 5 minutes, and logged into a Campbell Scientific CR10x datalogger.

The meteorological station is anchored in place as soon as possible in June (when ice is off lake) and remains in place until the Land-Water group leaves in August. This station measures air temperature and relative humidity (with Vaisala HMP45C) at ~1.5 meters height above the lake surface, and wind speed and direction (with Met One 014A anemometer) at ~2 meters height above lake surface.
