Abstract

The high-altitude meteorological data on the 27km resolution, with 149×149 grids in the whole country, are generated by application of mesoscale numerical model MM5. The raw data used by the model include the United States USGS data, including terrain, land use, the composition of the vegetation data, and so on. Original meteorological data are the reanalysis data of the US National Centers for Environmental Prediction of the NCEP/NCAR. According to the need of environment impact assessment (EIA), the high-altitude meteorological data contain 21 layers below 550 hPa height. The data mainly include atmospheric pressure, altitude, dry bulb temperature, dew point temperature, wind direction, wind speed, relative humidity. High-altitude meteorological data generated in this study, can be directly applied to the EIA prediction model and serve for EIA.
