Bjørndalen Weather Station
Live view of measurments | 360°
Weather station setup:
- Data logger CR1000X Campbell SCI
- CELL215 LTE modem
- HygroVUE10 Digital Temperature and Relative Humidity Sensor
- 05103 Young Wind Monitor
- S2-141 Apogee Instruments PAR/FAR Sensor
- SP-700 Apoee Instruments Albedometer
- 107 Thermistor Probe (0,1 m AGL Air Temprature)*
- CS655 SoiL Water Content Reflectometer 12 cm**
- 3 x 50 Ah VRLA battery
- 3 x 30 W PV modules
- 80 W wind generator Rutland 504
- Marlec’s HRSi Charge Regulator
*Later changed to measure soil temprature at 0.01 m bellow ground (see metadata). **Installed at a later date (see metadata)
The sampling interval and storing is 1 minute. Data are acquired every hour over LTE.
The power supply is an important component of the weather station: photovoltaic modules and wind turbine are mounted on separated mast – 4 meters distance from weather station to prevent interference with measured parameters.
