GnGVal (GEMS and GOSAT-GW Validation) overview

“GEMS L2 validation from polluted to remote areas over East Asia and co-development toward GOSAT-GW which will be launched in FY2023”

- We aim evaluation of GEMS L2 products of NO2, HCHO, O3 and aerosols, based on our ground/ship-based MAX-DOAS network (Japan, Korea, Pacific), co-located Pandora observations (Japan) as primary reference, with particular focus on

GMAP (GEMS Map of Air Pollution)

MAX-DOAS network over East Asia

- MAX-DOAS (Multi-Axis Differential Optical Absorption Spectroscopy) monitoring network over Asia have established for long-term measurement by providing vertically-resolved (or integrated) trace gases and aerosol extinction.
- Four sites (Yokosuka, Fukue, and Cape Hedo in Japan and Gwangju in South Korea) have been operated mainly since 2007.
