Practical method for forecasting the lower-atmospheric refractivity profile

A practical method is provided, which is used for forecasting lower atmospheric refractivity profile in short time. For an experiment which sounding the profile at sunrise and sunset when the refractivity varies violently, it is used to forecasting the profile. With time various parameters measured by microwave refractometer it can forecast the lower profile in 2-3 hours, the forecasted profile agreed with the sounded profile very well.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
