Latest Observations
Meteorological measurements are made every 6 minutes and Air-Water Flux measurements are made every 30 minutes. The data are downloaded via line-of-sight radio every six minutes. Data time stamp is UTC (Coordinated Universal Time): subtract 5 hours for EST, subtract 4 hours for EDT.
