Description
At the moment, AERONET or AMMA database shows a large volume of data loss. With only about 47% data set
available to the scientist, it is evident that accurate nowcast or forecast cannot be guaranteed. The calibration constants of
most radiosonde or weather stations are not compatible with the atmospheric conditions of the West African climate. A
dispersion model was developed to incorporate salient mathematical representations like a Unified number. The Unified
number was derived to describe the turbulence of the aerosols transport in the frictional layer of the lower atmosphere.
Fourteen years data set from Multi-angle Imaging SpectroRadiometer (MISR) was tested using the dispersion model. A yearly
estimation of the atmospheric constants over Ouagadougou using the model was obtained with about 87.5% accuracy. It
further revealed that the average atmospheric constant for Ouagadougou-Niger is a_1 = 0.626, a_2 = 0.7999 and the tuning
constants is n_1 = 0.09835 and n_2 = 0.266. Also, the yearly atmospheric constants affirmed the lower atmosphere of
Ouagadougou is very dynamic. Hence, it is recommended that radiosonde and weather station manufacturers should constantly
review the atmospheric constant over a geographical location to enable about eighty percent data retrieval
