Wind direction weather station DynaMet-2

evapotranspirationtemperaturewith data logger

The DynaMet-2 is a complete ETp (Evapotranspiration) weather station which included the DynaLog200 data logger and the MaxiMet 500 compact weather station kit. The rainfall sensor included is the TE525, which is a very rugged and accurate rainfall sensor. A soil temperature probe is also included. The system comes with all software for programming, data collection, and calculation of ETp. The DynaMet-2 is a low-cost, research grade, weather station ideal for research, commercial, or agricultural applications. Comes complete with a 6 ft Tripod, cross-arm, grounding kit, rechargeable battery and 10 Watt solar panel. Evapotranspiration Software Standard evapotranspiration modeling software is packaged with the Dynamet weather station. The purpose is to compute the potential evapotranspiration from short grass (ETP) in mm per hour on an hourly basis. A daily total in mm is also computed. The algorithms are based on the method originally proposed by Penman, but with several modifications by Dr. C.H.M. Van Bavel that updated the procedure. Whereas the original method was designed to give only daily totals from average daily weather data, the present method uses hourly input data and provides a more realistic picture of the evaporative demand. PENV software facilitates a variety of research and commercial weather tracking projects.
