  • 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 "CLDAS-V2.0" product is a grid fusion analysis product covering the Asian region (0-65°N, 60-160°E) with the resolution of 0.0625°×0.0625° and 1 hour, including six atmospheric driving field products (2m air temperature, 2m specific humidity, 10m wind speed, ground pressure, precipitation, and shortwave radiation), ground temperature analysis product, soil moisture analysis products (vertically divided into 5 layers: 0-5, 0-10, 10-40, 40-100, 100-200 cm), soil temperature analysis products (vertically divided into 5 layers: 5, 10, 40, 100, 200 cm) and soil relative humidity analysis products (vertically divided into 3 layers: 0-10cm, 0-20cm, 0-50 cm). The dataset is developed by using multiple grid variational assimilation called Space and Time Mesoscale Analysis System (STMAS), along with physical inversion, terrain correction based on the ground, satellite observations from various sources, and CLM3.5, CoLM, Noah-MP land surface model. The quality in China is superior to similar international products, and the spatio-temporal resolution is higher. The real-time product updates and releases in real timewith1 hour delay.
  • Global weather situation and rainfall forecasts over the next 10 days, Grid: 0.25°x 0.25°,60 vertical layers.
  • 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.
