Determination of Radiosonde Geopotential Height Biases by the Navy's Gobal DataAssimilation System. (Reannouncement with New Availability Information)

摘要

Recently, considerable attention has been given to systematic errors occurring inthe global radiosonde network. Many operational forecasting centers are involved in global radiosonde network. Many operational forecasting centers are involved in global data monitoring efforts using a short-range forecast from a global forecast model as the comparison tool (Baker 1991,1992; ECMWF 1988, 1989; Hall 1992; Hollingworth et al. 1986). The WMO International Radiosonde Intercomparison Tests (Nash and Schmidlin 1987) were major efforts that attempted to quantify the differences between the various radiosondes in use worldwide.
