In Doñana a manual weather station exists since 1978 equiped with analogical instruments from which EBD-CSIC personnel once a day, records maximum and minimun air temperature and total precipitation. This manual station has been supervised by the State Meteorological Agency (AEMET) until 2008. Since 2008, on the same site, AEMET has installed a new measurement station with modern instrumentation that allows automated data recording (temperature, precipitation, wind, humidity, etc.). Since November 2008 EBD-CSIC installed additional weather stations on different sites and varying time intervals, consisting of a multisensor of VAISALA brand. At some of these measure points other data related to the study of climate (soil humidity, soil temperature, solar radiation, CO2 flow, etc.) are being recorded. Additional weather stations in or near the Doñana area are managed by the Ministries of Agriculture and Environment of the Junta de Andalucía and by research entities like the National Institute for Aerospace Tecnology (INTA) and the Geological and Mining Institute of Spain (IGME)
