The research project main purpose is the evaluation of the EKO MS-711 spectroradiometer measurements at the Izaña Atmospheric Research Center (IARC-AEMET). The project foresees an intercomparison between instruments provided by EKO as well as other radiometers already installed at IARC-AEMET testbed. The main tasks consist of:
1) Comparison of the direct normal irradiance measurements performed by the collimated and rotating shadow band EKO spectroradiometers.
2) Evaluation and comparison of current methods for the retrieval of aerosol optical depth (AOD), precipitable water vapor (PWV), and the spectral irradiance extension, based on spectral DNI measurements from both collimated and RSB MS-711.
3) Comparison between indoor and outdoor spectroradiometer calibrations
4) Quantifying the measurement improvements in the measurement accuracy of the stray light corrected DNI measurements of the EKO spectroradiometer in the UV range against the NASA Pandora spectrometer.
5) Quantifying the measurement improvements in the measurement accuracy of the stray light correction measurements of the EKO spectroradiometer on the atmospheric parameters’ retrieval from (2)
