Development of formaldehyde retrieval algorithm for geotsationary satellites (GEMS)

Formaldehyde (HCHO) is mainly produced by the oxidation of hydrocarbons with minor direct emissions from fuel combustion, vegetation, and biomass burning. Because of its short lifetime (~1.5 hours), HCHO vertical columns from satellite measurements have effectively been used to provide constraints on its precursor emissions, especially for biogenic isoprene emissions, the oxidation of which is the largest natural source of HCHO globally.

Korean Ministry of Environment will launch a geostationary satellite (GEO-KOMPSAT) with Geostationary EnvironmentMonitoring Spectrometer (GEMS) over East Asia in 2019. We have been developing ans algorithm of HCHO retrieval in GEMS.
