New website of the Izaña BSRN station


The BSRN (Baseline Surface Radiation Network) is a global reference surface radiation network. One of the main objectives of this network is to validate and improve the radiative codes in climate models and establish long-term time series in order to detect changes or anomalies in solar radiation at ground. It is currently composed of more than 50 stations distributed throughout the planet. They are located in areas with different climates, which allow us to understand the different factors affecting radiation.

Izaña Atmospheric Observatory is part of the BSRN since March 2009. Within the collaboration agreement between AEMET and the University of Valladolid (GOA-UVA) a specific BSRN website for Izaña has been implemented. Real time measurements of global, direct, diffuse and UVB radiation are depicted in this web site. An algorithm to compare daily experimental measurements with model simulations (with LibRadtran radiative transfer model with real time actual data as inputs) has also been implemented. The Izaña BSRN web site shows the quality control procedures recommended by BSRN (QC Test) that are applied to global, direct and diffuse radiation measurements. Now measurements corresponding to 2011 are available in a graphic interface. In the following months the whole Izaña BSRN database will be available since 2009.
