Satellite aerosol optical depth (AOD) is widely used as a proxy for surface particulate pollution where ground monitoring is scarce, including in West Africa. This study tests whether this substitution holds for mineral dust by comparing MODIS MAIAC AOD (550 nm) with MERRA-2 mode...

Tropospheric formaldehyde (HCHO) is a short-lived oxidation product of methane and non-methane volatile organic compounds and is widely used as a satellite indicator of VOC oxidation. In single-year satellite records, HCHO and meteorological variables may covary because both foll...
