Abstract: One of the more difficult tasks confronting atmospheric researchers today is the acquisition of long-term radiometric measurements that encapsulate variability in the sky hemisphere as well as time. High quality spatial ...

Abstract: Occulting disk or shadowband arrangements are often applied to both spectral and broadband sensors in order to retrieve the total diffuse irradiance. However, there is difficulty in the application of a suitable diffuse ...

Abstract: In recent years, global warming concerns have focused attention on cloud radiative forcing and its accurate encapsulation in radiative transfer measurement and modeling programs. At present, this process is constrained by ...

Abstract: The authors examine the temporal variability of measured 415- and 611.7-nm spectral solar irradiance in cloudy stratocumulus conditions. This is accomplished by normalizing measured data by the equivalent irradiance for ...
