precipitation and clouds that are well delineated, quantitative reliability remains lacking. Arguably the biggest issue within NWP remains the proper representation of subgrid-scale precipitating convection within coarser-resolution models. Other schemes needing improvements include the parameterization of the effects of shallow convective clouds associated with the planetary boundary layer, microphysics of cloud formation (especially the initiation of ice-phase processes), exchanges between the atmosphere

1. Introduction Over the past 40 yr, our ability to forecast the weather and to simulate the climate of our planet with numerical models has strongly benefited from the growing understanding of the ocean–atmosphere system and from the constant progress in computer technology. Whether a given numerical model is able to properly forecast the state of the atmosphere up to 10 days or to produce realistic climatic simulations on monthly time scales strongly depends on its ability to represent the

Environmental Satellite System, and others ( Lambrigtsen 2003 ; Mo 2006 ; Muth et al. 2004 ). This paper utilizes only data from AMSU-A/B, which observes the frequencies listed in Table 1 ; the pressures at which the temperature weighting function for each channel peaks for the U.S. standard atmosphere are also listed together with the geophysical parameters to which each channel is most sensitive. c. Mesoscale model MM5 is a nonhydrostatic primitive equation limited-area nested-grid model with a terrain
