Reliable, Accurate and Quality Information to Ensure Better Weather Monitoring and Study of Climatology

Servei Meteorològic de Catalunya (SMC)

Areas of Activity: Environmental Quality

Sectors of Operation: Meteorology



The Meteorological Service of Catalonia (SMC) ( is responsible for managing weather observation and forecasting in Catalonia. These systems include the Automatic Weather Stations Network, integrated throughout the territory and which, at present, consists of 185 automatic weather stations (EMA).

The EMA is an essential tool in the field of meteorology and climatology, and is also necessary for a wide variety of applications that require the data they generate. Some of these applications and most common thematic areas are weather monitoring, climate studies, snow study applications - for forecasting the risk of avalanches-, agrometeorological applications - as a support tool in farm management: irrigation, pests, diseases, etc.-, forest activities – for the periodic calculation of fire danger, or air quality control.

The EMA does not require the presence of any observer, unlike manual weather stations, enabling installation in remote locations, as well as the possibility of taking records at a time when there may be hail, poor visibility, sleet or other adverse conditions. It also allows continuous data collection 24 hours a day, as this is objective data, without human intervention.

Provide the reliability, accuracy and quality of weather data is key to carry out optimum preventive and corrective maintenance. Specialised technical staff is responsible for carrying out this maintenance, for calibrating equipment and performing thorough quality control of the data. Ensure proper, continuous operation throughout the year and efficient time resolution of incidents are important objectives. The maintenance carried out at SMC weather stations guarantees a high percentage of valid and quality data, corroborating the quality of service they offer.

The data generated by the automatic weather stations network are automatically posted to the website to be consulted by the public, in a quick and easy way.
“Thanks to the maintenance of the weather stations, SMC achieves a high percentatge of valid and quality data, very useful for climate studies and weather monitoring.”


· Guarantee to monitor the weather variability and adverse weather conditions, where it is essential to have data in near real time, increasing the efficiency of the emergency services (i.e. on fires, torrential rain situations…).
· Provide accurate and reliable information for making an optimal climate study of the territory and improve predictive models of atmospheric phenomena.
· Support agricultural and forest management, by defining the optimal conditions to prevent the proliferation of pests in agriculture and ensure better management of water resources.
