| 摘 要： | Using the variational four-dimensional (4-D) data assimilation technique (the adjointmethod), we defined the error/mean-error ratios (EMER) of observational data. The plausibilityof marking the gross error using the EMER is investigated theoretically under some assumptions.Idealized numerical experiments are carried out using the simple Lorenz model to test the qualitycontrol scheme.
