BARJA, Boris et al. One year of Cloud Optical Depth measurements with sunphotometer in Camagüey, Cuba.. Revista Boliviana de Física [online]. 2012, vol.20, n.20, pp.1-3. ISSN 1562-3823.

One year of Cloud Optical Depth (COD) measurements obtained with the radiometer (sunphotometer Cimel CE - 318) are presented. As the first step a validation method is proposed in order to confirm the cloud in the measurement. This method is based in the cloud information derived from the actinometrical observations and radar data. In the second step of the work, the statistical results from the one year of the COD measurements in Camagüey are analyzed. The results show the high quality of COD measurements at Camagüey. The analysis of the COD frequency shows one peak close to 15. Similar behavior occurs each month. The mean COD average value for the entire period is 27.2, with a standard deviation of 17.3. The mean monthly minimum and maximum value of COD occur in December and May, respectively. The diurnal cycle of the mean hourly COD values shows an increase in the afternoon hours. In the afternoon the number of cases measured decrease. The preliminary results shown in this paper constitute the first report of such measurements in the country.
