Abstract: Spectral measurements of the ultraviolet region of the solar spectrum have been made at Reading, southeast England (51.5°N) since July 1989. The data presented here show the daily and annual variability of and within the ...

Abstract: his study describes a dual-channel array spectrometer system designed to make high-frequency simultaneous spectral global irradiance and direct solar irradiance measurements covering the visible and ultraviolet wavelength ...

Abstract: High-resolution measurements in the spectral region of 280?400 nm using a double monochromator are compared with detailed radiative transfer calculations at Reading, United Kingdom (52°N, 0°), for clear and totally overcast ...

Abstract: A new spectroradiometer for spectral measurements of ultraviolet (UV) atmospheric radiation (290?400 nm) using a charge coupled device (CCD) as a detector is introduced. The instrument development is motivated by the need ...

Abstract: Aerosols play an important role in attenuating solar radiation reaching the earth's surface and are thus important inputs to climate models. Aerosol optical depth is routinely measured in the visible range but little data ...

Abstract: The Convective Storm Initiation Project (CSIP) is an international project to understand precisely where, when, and how convective clouds form and develop into showers in the mainly maritime environment of southern England. ...
