An estimate of solar radiation over Bangladesh

Globa1 solar radiation distribution over Bangladesh has been estimated with a modified Angstrom equation. Based on data for five; years at Dhaka, a regression formula has been derived for Bangladesh. This equation is then applied to sunshine and cloudiness data from 6 stations In Bangladesh for the computation of global solar radiation for the twelve months of a year.
 
 Spatial distribution of global solar radiation is found to be nearly uniform over the whole country. Global solar radiation is seen to be maximum exceeding 19.68 MJm-2day-l in March-April and minimum, less than 12.56 MJm-2 day-l In January.
 
 Values of outgoing long wave radiation for the twelve months of a year have been computed using Brunt's empirical equation and…
