In collaboration with EPSON METEO, LSI LASTEM supplied and installed a new weather station on the roof of the tallest building in Italy. Due to its particular location (200 m above sea level without any obstacle in the range of several kilometers), this station is a point of high interest for the quality of its measurements. Data are managed by EPSON METEO for weather forecasts in the city of Milan and the whole Lombardy region. The station is equipped with E-Log data logger and Air Temperature&Relative Humidity, Wind Speed and Direction, Global and Direct Irradiance, Rain gauge and Pressure sensors. E-Log is connected to EPSON METEO by WAN network.
