Abstract: A model is developed for use in estimating rainfall attenuation at frequencies above 3 GHz in showers and other types of sporadic rainfall, usually associated with atmospheric convective activity. The model assumes a ...

Abstract: Thermopile pyranometers? thermal offset has been recognized since the pyranometer?s inception. This offset is often overlooked or ignored because its magnitude is small compared to the overall solar signal at higher ...

Abstract: Although most measurements of total downwelling shortwave irradiance are made with pyranometers, the World Climate Research Program?s Baseline Surface Radiation Network has recommended the use of the summation of shortwave ...
