| Abstract | In this work, the depletion of total solar ultraviolet (TUV) radiation and erythemal weighted solar ultraviolet (EUV) radiation by aerosol in clear sky conditions was investigated based on the data collected at Nakhon Pathom station (13.82°N, 100.04°E) in Thailand. Solar spectral ultraviolet radiation was measured by a spectroradiometer (Bentham Instruments Ltd., model DMc150), in addition to aerosol optical depth (AOD) at 340 nm measured by an AERONET sunphotometer (Cimel Electronique, model CE-318). The total ozone column (O3) retrieved from OMI/AURA satellite data was also used. The data period used in this work were from January 2017–December 2018 at Nakhon Pathom station. The EUV was obtained from the solar spectrum and erythemal weighted action spectrum. A special technique was employed, using UV data calculated from the UVSPEC, a radiative transfer model, to extract the variation of TUV and EUV only as a function of AOD. Equations relating TUV to AOD and EUV to AOD were established. TUV and EUV were found to decrease linearly with the increase of the AOD. |
