High-Resolution Satellite Remote Sensing of the Atmospheric Composition over the Middle East
Abstract
The Middle East, comprised of many developing countries, is one of the critical regions where the issue of air pollution is highlighted. Lack of accurate and complete datasets of the atmospheric constituents has made it difficult to define and implement pollution reduction policies . Satellite observation of air composition has been drastically improved over the p ast two decades. After the launch of TROPOspheric Monitoring Instrument (TROPOMI) on the Sentinel-5 Precursor satellite in October 2017, TROPOMI has been delivering remarkable high-quality retrieval data for constituents of atmospheric composition with fine spatial resolution. As a case study , we compare nitrogen dioxide (NO2 ), formaldehyde (HCHO) and carbon monoxide (CO) products from TROPOMI for Tehran, one of the megacities of the Middle East subjected to persistent air pollution. These datasets have been collected throughout the year, giving much more complete spatial and temporal coverages as opposed to scattered in situ air quality monitoring sites. Changing pattern of these constituents over seasons of the year accompanied with different weather parameters such as wind speed, temperature, and atmospheric mixing , are investigated by sampling global analysis at satellite sounding time and locations . This study will broaden our vision in air quality condition of the region and help to increase the capability of providing effective pollution reduction strategies.
