Houser Quality control for data assimilation One of the major components of any data assimilation system is quality control of the input data stream. Quality control is a pre-assimilation rejection or correction of questionable or bad observations, which begins where the remote sensing product quality control activities leave off. The observation data from remote sensing systems contain errors that can be classified into two types: 1 natural error (including instrument and representativeness error); 2 gross error (including improperly calibrated instruments, incorrect registration or coding of observations, and telecommunication error).

VIC vs TOVS surface temperature comparison 1981–99. 98 obtained from the study. 4) indicates a consistent model performance in simulation of land surface temperature. 14 MODEL CHARACTERIZATION OF EXTREME EVENTS – DROUGHTS AND FLOODS The VIC-3L model simulated soil moisture for the Upper Mississippi River Basin were studied in detail to characterize the extreme events such as the Midwestern drought during summer 1988 and the Upper Mississippi flood during July 1993. 5. Upper Mississippi River Basin averaged monthly soil moisture (0–140 mm).

Since then there has been a plethora of one-dimensional KF and variational assimilation studies. Copyright © 2005 Taylor & Francis Group plc, London, UK 30 Jeffrey P. Walker and Paul R. Houser Georgakakos and Baumer (1996) were one of the first to use the KF to update a hydrologic basin model with near-surface soil moisture measurements. Results showed that even when the observations carried substantial measurement errors, estimation of soil moisture profiles and total soil moisture storage was possible with an error that was smaller than that achieved without the use of remotely sensed data.
