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.
How does a weather station work?
The sensors execute the “raw” measurements at customizable time intervals of a few seconds. The data logger stores all the data and processes some calculated quantities, such as the hourly statistics, the standard deviation, the average for each quantity. LSI Lastem data loggers are able to perform, store and transmit even more specific and complex calculations such as crosswinds for airport safety or evapotranspiration calculations for agrometeorology.
At pre-configured intervals, the communication system transmits the data. stored in the data logger, to the web or a traditional server. From the LSI Lastem dataloggers it is also possible to manage the dispatching of automated alert messages, either through SMS messages or emails, when pre-set thresholds are exceeded.
Our professional solutions
Since 1972, LSI Lastem has been developing, manufacturing, and selling the most comprehensive range of high-quality automatic weather stations worldwide. LSI Lastem equipment is suitable for many types of applications, ensuring accurate and reliable weather observation for both portable and long-term monitoring.
LSI Lastem weather stations include sensors, data acquisition systems, software, and installation accessories, forming a complete surface meteorological observation system, according to WMO standards, which can operate individually or integrated inside a network.
The wide range of sensors covers virtually any meteorological parameter, such as wind direction and speed, temperature, relative humidity, solar radiation, rain, atmospheric pressure, evaporation, visibility and many more.
All LSI Lastem data loggers for environmental applications are characterized by low energy consumption, are resistant to harsh environmental conditions and support a wide range of signals and communication protocols.
This makes LSI Lastem a unique reference in the field of professional weather monitoring.
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.
