Abstract: The total cloud cover is deduced from measurements of the percent of possible sunshine at 72 locations in the United States. This sunshine-derived total cloud cover is then compared to conventional ground-based observations ...

Abstract: Using data from sunshine recorders in the contiguous United States, the mean interannual cloud-cover variations at 103 locations are calculated. A typical location has a mean absolute year-to-year variation in cloud cover ...

Abstract: Rayleigh optical depths are calculated for six standard atmospheres using the latest value of the depolarization factor (?n = 0.0139). Present uncertainties in the Rayleigh optical depth of ±0.16% exist for the values ...

Abstract: Two external forcing functions are examined in their relationship to temperature records at individual locations. Postulated changes in solar luminosity, deduced from sunspot structure, and the dust veil hypothesis are ...

Abstract: The pyrheliometric measurements at three locations in the United States axe examined to determine if there are trends in atmospheric transmission. Although the radiation values at Madison are depressed in the 1940's because ...

Abstract: The analyses of Cess are extended to consider global relationships among the earth's radiation budget (including solar insulation and changes in optically active gass), cloudiness, solar constant, volcanic aerosols, and ...
