NCEP reanalyzed data used for atmospheric environment prediction

Abstract:

In order to provide reference for using the unconventional meteorological data in environmental prediction, based on AERMOD model,the standard meteorological scenario and NCEP meteorological scenarios were constructed by using the 2011 Harbin station-observed data and NCEP reanalyzed data, and the d index and relative error on pollutant prediction concentration between NCEP meteorological scenarios and standard meteorological scenario were analyzed. The results show that the NCEP high altitude meteorological data, cloud data can be used in atmospheric environment prediction, but the NCEP data cannot replace the ground automatic weather station data for atmospheric environment prediction.
