Powerful, rugged and highly flexible weather station Designed for use in severe weather conditions Wide choice of sensors including soil moisture Cellular modem communications Compatible with DeltaLINK Cloud online data sharing platform
The advanced WS-GP2 Automatic Weather Station is based on the powerful GP2 Data Logger. It is an ideal solution for research and environmental monitoring applications at remote and exposed sites. The WS-GP2 provides a highly rugged and flexible system – users can select the optimal combination of sensors, logger, power and communications.
The standard WS-GP2 includes sensors to measure rain, solar radiation, soil temperature, wind speed and direction, relative humidity and air temperature.
The GP2 Data Logger has the power and flexibility to handle almost any environmental sensor, which means the WS-GP2 Weather Station can be as simple or as complex as your application requires. Even after installation, it’s easy to adapt the system to your specific needs. Optional sensors include barometric pressure, soil moisture, soil EC, UV, PAR, albedo, net radiation, total and diffuse radiation, and evaporation.
Data can be easily collected by laptop via USB, or remotely using the cellular modem options. DeltaLINK Software makes it easy to set up recording intervals and to view and download stored data.
Data presentation options include wind rose, gusts and average (including direction and vector average).
The GP2 Data Logger supports SDI-12 inputs. GP2s supplied before March 2016 can be easily updated via a software download.
Key features:
For researchers interested in evapotranspiration, degree days, disease prediction, wind chill factor, dew point, PID control, etc. the GP2’s advanced features will open up exciting possibilities.
The WS-GP2 Weather Station and DeltaLINK Software (versions 3.7 and later) enables the full ASCE/FAO-56 Penman-Monteith equation for calculating reference evapotranspiration (ETo).
ETo is calculated by the WS-GP2 Weather Station using the available measurements of relative humidity, wind speed, solar radiation, and air temperature. This ET implementation includes the ability to vary crop albedo/LAI, canopy resistances, crop height and sensor heights.
The functionality can be easily accessed by users as a selectable recording option within DeltaLINK. Calculated ET can be recorded as hourly and daily values – and may be used in further bespoke calculations or to guide field irrigation decisions.Specification
