The Izaña Tesbed site supporting different field campaigns of radiation/aerosols prototypes
The Izaña Tesbed site has been used for different field campaigns of radiation/aerosols prototypes, such as the new Precision Solar Spectroradiometer (PSR), developed at PMOD/World Radiation Centre (WRC, Davos Switzerland), which will replace current filter sunphotometers for long AOD and absolute solar irradiance measurements. This instrument has been absolutely calibrated at Izaña and compared with other reference photometers. Preliminary stellar measurements have also been performed.
The Izaña tesbed has been the facility of an intensive 2-month campaign for the determination of the NIR irradiance spectra will be used to retrieve the top-of-atmosphere (TOA) solar spectral irradiance through wavelength ranges free of O2, O3, CO2 and H2O absorption the Bouguer-Langley technique. The results obtained within this campaign are expected to solve some discrepancies observed in published TOA solar spectra in the infrared range. An accurate knowledge of the NIR TOA solar irradiance is important due to its role in Earth radiative budget, namely atmospheric and upper layer of the ocean absorption processes. NIR TOA is also needed to validate semi empiric models of solar atmosphere. Results have been reported by Bolsée et al. (2014).
Two campaigns of TENUM Calitoo hand-held photometers in 2014 and 2015.
