Model products

Datasets and products including domestic and foreign weather forecasting model and environmental forecasting model outputs.

  • T639L60 global medium range NWP model products have higher resolutions, its global horizontal resolution reaches 30 km, its vertical resolution is 60 layers, and its model top reaches 0.1 hPa. The maximum time validity of prediction is up to 240 hours, and the predicted elements include pressure, geopotential height, temperature, pseudo-adiabatic potential temperature/pseudo-equivalent potential temperature, dew point temperature, dew point deficit (or deficit value), u component of wind, v component of wind, vertical velocity (pressure), relative vorticity, relative divergence, specific humidity, relative humidity, evaporation amount, snow depth, water runoff, snowmelt amount, precipitation amounts, divergence of water vapor flux, water vapor flux, vertical component of moist potential vorticity, horizontal component of moist potential vorticity, liquid content of surface water storage pool, temperature advection, vorticity advection, etc. The data files adopt grib2 format, which are disseminated on a daily basis at 00:00 and 12:00 UTC.

  • The model prediction products for the East Asia region are generated from the operational GRAPES_Meso regional ensemble prediction system. The spatial resolution of the model products is 10km, and the temporal resolution is 3 hours. The time validity of the prediction is up to 72 hours, and predicted elements include pressure, geopotential height, temperature, pseudo-adiabatic potential temperature/pseudo-equivalent potential temperature, dew point deficit (or deficit value), u component of wind, v component of wind, vertical velocity (geometric), relative humidity, precipitation amounts, moisture flux, divergence of moisture flux, etc.. The data files adopt grib2 format, which are disseminated on a daily basis at 00:00 and 12:00 UTC.
