Detection and Quantification of CO Pollution Sources combining TROPOMI CO and Suomi-NPP Observations
Abstract
The Tropospheric Monitoring Instrument (TROPOMI) was launched on 13 October 2017 as the only payload of ESA's Sentinel-5 Precursor (S5-P) satellite. One of the primary targets of the mission is to measure the atmospheric concentration of carbon monoxide (CO) with daily global coverage and a spatial resolution of 7x7 km. CO is emitted to the atmosphere by incomplete combustion and is established as a tracer for air pollution and its transport on regional and global scales. Based on our experience developing the operational CO processor for S5-P, we show in this contribution the potential of combining TROPOMI CO with the Suomi-NPP measurements. The S5P satellite flies in loose formation with Suomi-NPP with a time difference < 3.5 minutes and delivers temporal and spatial collocated measurements. We use Suomi-NPP VIIRS measurements to filtered the TROPOMI CO data for clear-sky atmospheric conditions. Moreover, VIIRS Active Fire Data identify the geolocation of wild fires which is required to estimate the CO emissions from the TROPOMI CO data. The work represents an initial effort to establish an automated detection and quantification of CO pollution sources using S5-P and Suomi-NPP measurements in a synergistically manner.
