Multiyear Satellite Total Ozone Column Dimension within West Africa

Total Ozone Mapping Spectrometer (TOMS*) mechanisms have been flown on NASA/*GSFC satellites more than 20 years. They present close to realdnine ~o/.?one data pro Atmospheric Science Research. As elemental of preface energy structured to build up a Lidar base in Nigeria for monitoring the atmospheric ozone and aerosol stratum. The monthly mean TOMS* total column ozone measurements amid 1978~1999 have been evaluated. The tendency of the total column ozone illustrates a spatial and sequential dissimilarity with cryptogram of the Quasi Biennial Oscillation (QBO) all through this 21-year research epoch; The standards of TOMS* total ozone vertical, over Nigeria (4-15o

Analysis on Many-year Ground Based Sunphotometer (AERONET) Aerosol Optical Properties and its Similarity with Satellite Observations in IIorin, Cape Verd, Agoufou and Banizoumbou in West Africa

Sahelian in West Africa within Long 20oW: 20oE, Lat 0:30oN through its climatic process and geographical environmental state is a major region for the distinctive of universal atmospheric aerosol optical properties. This research evaluates the spatial and secular variant of Aerosol Optical Depth AOD-441nm, aerosol particulate size categorization Angstrom exponent ?441-676nm at different four sites IIorin, Cape Verde, Banizoumbou and Agoufou. Outcomes for everyday AOD-441nm differences as well as the regular and yearly changes are presented to ascertain the aerosol climate changes in the region. We evaluated satellite resultant data of Total Ozone Mapping Spectrometer for Aerosol Index MODIS Terra and Aqua, TOMS AI with individuals of ground based Sunphotometer AERONET dimensions. Generally, presently exit good connection between ground-based AERONET dimensions and MODIS Aqua and Terra with correlation coefficients, R2, 0.9 details in all stations. Though low coefficients low as 0.41 were ascertained in all the locations for regressions amid TOMS AI and ground based Sunphotometer AERONET data. &nbsp
