Urban Weather Station
(AITeCH project)
Urban Weather Station is operating in the old town, within the complex of the Ospedale dello Spirito Santo immediately adjacent door Rudiae in Lecce (40 ° 21' 3''N - 18 ° 9 '44''E). The weather station consists of two parts: an instrumented mast (2.3m) placed on the roof of the building (total height from the road, 14.2m) and a second set of measuring instruments placed in the courtyard of the building. In total, the measurement station is composed by:
A two-dimensional sonic anemometer (WindSonic) to measure the wind field on the instrumented mast. Unlike electro-mechanical anemometers this type of instrument does not have blind spots in detection of the direction and speed does not have a threshold below which the measures become unreliable. The absence of moving parts eliminates the need to calibrate the airspeed indicator on the field and makes it ideal for long-term studies.
Two slow thermo hygrometers (CS215, Campbell Scientific) to measure the temperature and relative humidity, one of which is mounted on the instrumented mast and another placed in the courtyard, two radiometers (Micros TRADNT V) for the measurement of net radiation. A radiometer is mounted high on the roof and one down in the courtyard.
A rain gauge ARG100. The measurement system is a tipping bucket (contact closure). The diameter of the catchment is 254 mm. The resolution is 0.2 mm
All sensors are interfaced to a datalogger (CR200, Campbell Scientific) for storage of data continuously. The datalogger is connected to a mini PC that allows you to have a remote control and weather station with a GSM system to transfer data to our central server to ISAC-CNR and are available on this website
