Abstract: More precise radiation measurements in the Antarctic are required for studies designed to assess the radiation and heat budgets of that area. These requirements inspired the present investigation which is aimed at the ...

Abstract: Atmospheric turbidity (aerosol optical thickness) was measured with sunphotometers across the Los Angeles Basin. Automobiles were used for east-west traverses of the metropolitan area (a distance of ?100 km) on two days ...

Abstract: As part of the Los Angeles Reactive Pollutant Project (September?November 1973) continuous measurements were made of incident ultraviolet and total solar irradiance at six sites (five urban and one nonurban) over the Basin. ...

Abstract: The formation of dew or frost on the outer glass hemisphere of pyranometers was found to cause erroneous values of incident hemispheric solar radiation. An air flow system was designed to continually ventilate the instrument ...

Abstract: Some 8500 observations of atmospheric turbidity, taken at Raleigh, North Carolina from July 1969 to July 1975 are analyzed for within-day and day-to-day variations and their dependence on meteorological parameters. The ...
