Introduction The National Oceanic and Atmospheric Administration (NOAA) series of satellites carry instruments designed to measure atmospheric temperature and moisture. These instruments are the High-Resolution Infrared Radiation Sounder (HIRS), the Advanced Very High Resolution Radiometer, and the Microwave Sounding Unit (MSU). HIRS is the primary instrument for atmospheric sounding. It is well known that some of the 4.3- μ m HIRS channels are contaminated by solar radiation ( Wark 1993

physical parameterization schemes. Moreover, a minimization process is time consuming when the description of the control variables is global. Therefore, only fast physical parameterizations can be linearized for global variational analyses of the atmosphere. Examples of physical parameterizations for 4D-Var can be found in Janisková et al. (1999) and in Mahfouf (1999) . This study examines two infrared radiation schemes for application in 4D-Var. They use different parameterizations because

al. 1996 ), and downwelling longwave radiation ( Francis and Hunter 2007 ). Turner (2005) reports that the seasonal cycle in liquid droplet effective radii is likely related to seasonality in aerosols (e.g., Sirios and Barrie 1999 ), which have a climatologically significant impact on cloud emissivity (resulting in higher downwelling infrared fluxes) ( Lubin and Vogelmann 2006 ; Garrett and Zhao 2006 ). Further, several studies have suggested that Arctic cloud microphysics are spatially

1. Introduction Placing a high-spectral-resolution infrared (IR) sounder in geostationary orbit will provide high temporal resolution of the three-dimensional fields of moisture, temperature, and wind with much greater vertical resolving power than the broadband legacy sounders on the current Geostationary Operational Environmental Satellite (GOES) series ( Schmit et al. 2009 ). Greater information about the time evolution of clear-sky horizontal and vertical water vapor, temperature, and wind
