Weather monitoring: what is it for? Meteorological measures have multiple uses that make them of primary importance for monitoring areas, of different sizes, and for managing extreme situations, such as floods, exceptional snowfalls, strong winds or harmful solar radiation. Professional weather stations are used to monitor the parameters that are the basis of the complex algorithms of forecasting models. Long time series of reliable and quality weather data make a valuable contribution to climate change research both locally and at the mesoscale. What is a weather station made of? A weather station is typically composed by a series of sensors for the measurement of the various parameters: solar radiation, wind direction and speed, air temperature and humidity, precipitation, atmospheric pressure and others. All the data are stored in a data logger, which has the task of archiving them, processing the first calculated quantities, and managing the communication of the data to a web-based software or to a traditional server. The weather station is installed on one or more physical structures such as poles and towers depending on the place of installation. There are some clear prescriptions from W.M.O. (World Meteorological Organization) on the proper installation of the weather stations, to obtain quality data that are representative of the climatic zone. The continuous operation of all equipment is guaranteed by the power supply, either from the power grid or solar panels. In this last case, the size of the panel is calculated based on the number of sensors, the rate of data acquisition and transmission and the availability of solar radiation (latitude, frequent or long-lasting cloud cover). The station is completed by the data transmission system, via modem, radio or more rarely via cable.

**KME Professional weather stations** KME Weather Stations are professional and economical complete solutions for obtaining the typical weather parameters such as air temperature and relative humidity, wind speed and direction, atmospheric pressure, solar radiation and rainfall. The station consists of a basic kit including sensors, E-Log data logger and 3DOM software for programming and data com-munication. Starting from the selected basic kit, it is possible to integrate additional sensors, communication systems, pow-er supply, assembly accessories and other software apps, selected from the LSI Lastem range. **Compact weather station** Compact Weather Stations are based on AIO (All-In-One) meteorological sensors and a powerful Alpha-log data logger. AIO sensors can monitor multiple meteorological parameters. They are compact, maintenance free, and have a long service life. AIO sensor simplifies installation and reduces costs compared with multiple individual weather sensors. A rain gauge can be selected as additional separate sensor (tipping bucket) for a better accuracy over the total amount of rainfall and intensity. It can also be included inside the All-In-One sensor (optical). **Complete weather station** Synoptic Weather Stations comply with the most demanding requirements in term of compliance to WMO standards as reported in the “Guide to Instruments and Methods of Observation (WMO-No. 8)“. These weather stations can include the standard typical 7 parameters for ground-based meteorological observation. It is also possible to add many other types of sensors. Technical file
