抄録

A sensitivity analysis on aerosol parameter estimation with measured solar direct and diffuse irradiance is made together with proposed solar direct and diffuse irradiance measuring instrument of solar direct and diffuse irradiance (optical Fiber Guided Hemispherical Spectral Radiometer : FighSR). Sky-radiometer and aureole-meter is well known instrument with sun tracking mechanics which allows measurements of solar direct and diffuse irradiance for estimation of aerosol parameter. The proposed measuring instrument also allows solar direct and diffuse irradiance measurements without sun tracking mechanics so that it is comparatively light and small. Therefore, it is portable and is easy to bring to test sites for field campaigns. Aerosol parameter estimation error caused by measurement error of Sky-radiometer, aureole-meter as well as the proposed FighSR instrument is also discussed. Experimental results show that Root Mean Square Error : RMSE of refractive index for 1.747-i0.0056 of refractive index at 500nm is 0.025 (Real) and 0.008 (Imaginary) when less than 5% of solar direct and diffuse irradiance measurement bias error is taken into account for both FighSR and Sky-radiometer. Meanwhile RMSE of Junge parameter is 0.25 when the Junge parameter is 3.5915 for the same bias error.
