• GEOS-FPIT — semi-frozen global atmospheric model developed by the Global Modeling and Assimilation Office ( GMAO) at NASA Goddard Space Flight Center. The model runs from 2000.01.01 through present and is updated 3–4 times a day. Model resolution: 0.625° × 0.5° × 3^h × 72 layers. Used datasets: layer pressure thickness, air temperature, and specific humidity.
• MERRA — reanalysis global atmospheric model developed by the Global Modeling and Assimilation Office ( GMAO) at NASA Goddard Space Flight Center. Updated once a month. Model resolution: 0.67° × 0.5° × 6^h × 72 layers. Used datasets: layer pressure thickness, air temperature, and specific humidity.
