Abstract
Abstract—The frequent failures of ground measuring devices e.g. radiosonde, weather stations in developing regions is worrisome. At the moment, AERONET or AMMA database shows a large volume of data loss. With only about 47% data set available to scientist, it is evident that accurate nowcast or forecast cannot be guaranteed. We propose that the challenge is not measuring device design error but systemic. A dispersion model was adopted from previous work to incorporate salient mathematical representations like Unified number. Fourteen years data set from Multi-angle Imaging SpectroRadiometer (MISR) was tested using the dispersion model. It revealed that the average atmospheric constant for Niamey-Niger is a_1 = 0.77975, a_2 = 0.693021 and the tuning constants is n_1 = 0.140187 and n_2 = 0.759236. Also, the yearly atmospheric constants affirmed the lower atmosphere of Niamey 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.
