Gosat Partial Column Observation for Better Quantifying Urban CO2Flux

The Japan's greenhouse gases observing satellite (GOSAT) observes the atmospheric CO
2
change for a decade. JAXA EORC provides the GOSAT tropospheric partial column product V2 from 2009 up to 2021 by using both SWIR and TIR spectra. The CO
2
enhancement derived from the tropospheric partial column product has demonstrated the change detection over urban cities by the COVID-19 effect. The CO
2
partial column product has a potential for better quantifying urban CO
2
flux.
