A weather station is a system integrated by sensor or measure devices of different typology whose goal is to measure the time variability of the weather conditions from a specific site, through a discrete sampling of physic variables called observations.
Currently, the Instituto de Sistemas Fotovoltaicos Concentration (ISFOC), owns a net of automatic-measuring weather stations, being operative 24 hours a day. 365 days a year. ISFOC automatic weather stations are designed to measure and characterise of the solar radiation, ranging all its components, from global to direct and diffuse, although they focuses on the energy directly coming from the solar disc, the Direct Solar Radiation (DNI), the one feeding the CPV technology. This measuring network's main goal is to support the research activity of our Institute, in the common fiel of the Meteorology and the Concentration photovoltaic Technology (CPV). ISFOC automatic weather stations are in compliance with the Spanish R&D General Plan targets dor Solar Concentration Photovoltaics, issued by the own Institute in 2008 in regard with Castile- La Mancha region needs. Those are listed below:
ISFOC automatic measuring network is made up by four weather stations installed next to the ISFOC CPV plants, in Castile-LA Mancha(Spain).
