Abstract

Using the series of hourly broadband solar radiation observations from the Camagüey (21,4 degrees N y 77,85 degrees W) meteorological station, covering the years 1985 to 2007 a series of aerosol optical depth estimates is de-rived. For such a goal a Bouger-Lambert-Beer law implementation method developed by Gueymard (1995, 1998) is employed. Because this method requires the selection of hours with clear sky conditions, the characterization of the monthly and hourly frequencies of that condition for Camagüey is conducted. The mean hourly and monthly courses of the aerosol optical depth as well as its trends during the period under analysis are studied. Results are similar to the observations registered in Barbados (13,18 degrees N; 59,43 degrees W) for the period 1996-1999 using solar photometry. The influence of Saharan Dust is evident in the annual course of the aerosol optical depth, causing its maximums to occur in summer. Comparisons with other short period’s observations also show agreeing results. Aerosol optical depth trends during the period of study are -1.46/(1000 x year), statistically significant at the 95 per cent level, in agreement with reports from other regions of the planet like in Northern Africa, Middle East and Central Asia.
