Adaptive bias correction for satellite data in a numerical weather prediction system

T. Auligné, A. P. McNally, D. P. Dee
2007 Quarterly Journal of the Royal Meteorological Society  
VarBC is compared with an offline adaptive and a static bias correction scheme. In simulation, the three schemes are exposed to artificial shifts in the observations and the background.  ...  In parts of the atmosphere where no radiosonde observations are available, the radiosonde network still imposes an indirect constraint on the system, which can be enhanced by applying a mask to VarBC.  ...  Appendix: Constrained adaptive bias correction A different simulation is performed to illustrate the influence of a constraint on the bias correction.  ...
