[ABSTRACT] Top cloud reflected solar radiance measurements directly recorded by satellites at various spectral bands and observation conditions are used to understand clouds’ optical and physical characteristics. The magnitude of these radiance measurements modulates the energy balance of the Earth through absorption and scattering. The accuracy of the data obtained highly depends on the sensitivity of the recording sensors. The Visible and thermal infrared channels are mainly employed to extract, through various inversion techniques, cloud microphysical parameters such as the brightness temperature, optical depth, effective radius, top cloud temperature etc. This study examines reflectance and optical depth retrievals derived from cloud radiative measurement data collected by the SVISSR (Stretched Visible Infrared Spin-Scan Radiometer) and the MODIS (MODerate resolution Imaging Spectroradiometer) sensors onboard the geostationary satellite (GMS-5) and the polar-orbiting satellite (Terra) respectively. MODIS cloud optical depth as well as reflectance appears systematically higher than the SVISSR corresponding data. And, the largest differences are mostly seen in thick cloud areas. To understand these discrepancies, a cloud classification based on the split-window method, has been conducted and, the influence of various parameters on the measurements and retrievals among which, dimensional radiative effects (asymmetry of the clouds) and the sun-earth-satellite viewing geometry are examined.
