Sensors / Procedures
ENEA Santa Teresa meteorological station
The data acquisition system is a Campbell Scientific data-logger CR10. The programmable module reads the input signals from the sensors (max 12), generates the time clock, communicates with the PC and stores data (64 Kb RAM) also providing output processing instructions. The CR-10 is connected via a serial port to a PC that processes the meteo data. The CR10 datalogger driven by the Loggernet v2.1 developed by Campbell Scientific allows one to program a specific instructions set that defines the sensors number/type, the sampling rate and the calibration coefficients. Loggernet allows one to schedule data collection in automatic mode. The specific program customized for the S. Teresa meteorological station acquires data according to WMO (World Meteorological Organization) standard procedures: 1. Wind speed and direction are sampled every 10 seconds. These parameters are averaged over 10 minutes providing mean horizontal wind speed, resultant mean wind speed, resultant mean wind direction, standard deviation of wind direction; 2. Air temperature, air humidity, barometric pressure, solar global radiation are sampled every 10 seconds. These parameters are averaged over 10 minutes providing mean values; 3. Precipitation is sampled every 10 seconds and the averaged value is provided avery 10 minutes.
