The plots show the model forecasts of smoke AOD in comparison with NASA AERONET (Aerosol Robotic Network) observations for various sites in Southeast Asia.

AERONET is a federation of ground-based remote sensing networks established by NASA and collaborators from national agencies, institutes, universities, individual scientists and other partners. For more than 25 years, the project has provided long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterisation, validation of satellite retrievals, and synergism with other databases. The network imposes standardisation of instruments, calibration, processing and distribution.

GEMS is the world's first geostationary air quality monitoring mission, developed by the S. Korean National Institute of Environmental Research (NIER) and launched in February 2020 onboard the GEO-COMPSAT-2B satellite. The UV-Visible hyper spectrometer measures atmospheric composition and provides hourly daylight tracking of aerosols over East Asia at a nominal spatial resolution of 3.5x8km. Final AOD data are available at three distinct channels: 354 nm, 443 nm, and 550 nm along with Aerosol Effective Height retrievals.
