alternate systems, where a temporal mismatch arises in balance equations between instantaneous analysis fields and forecast variables that are accumulated over some model integration period. The IAU additionally limits model spindown as the GEOS DAS progresses over the 6-h window and allows for the hourly temporal resolution of output variables. The atmospheric moisture budget for MERRA may be written as where Here, W υ is the column-integrated water vapor (precipitable water); W l is the total

step. Following a form similar to Trenberth (1997) , the MERRA total energy equation integrated over the atmospheric column may be written as where A E is total energy in the atmospheric column, is the horizontal transport of total atmospheric energy, R top is the downward net radiative flux at the top of the atmosphere (TOA), F sfc is the upwelling net surface flux, L υ is the latent heat of vaporization, L f is the latent heat of fusion, W υ is column-integrated water vapor

approximately 750 cm −1 for channel 7, 900 cm −1 for channel 8, 1225 or 800 cm −1 (varied for different satellites) for channel 10, and 1365 cm −1 for channel 11 [see Shi et al. (2008) for variations of central wavenumbers from satellite to satellite]. Channel 7 observes near-surface air temperatures. Channel 8 is a surface window channel. Channel 10 is in the water vapor continuum band for near-surface observation. Channel 11 is a lower-atmosphere water vapor channel. This study examines the high

referred to as the thermal effect and the effect of wind speed as the wind effect. SHF is an energy flux that is directly related to a change in temperature. It is different from latent heat flux (LHF), which is an energy flux associated with the evaporation of water vapor from the ocean surface. In the tropical oceans where the SAT is close to SST, SHF is about one order smaller than LHF. Because of this, LHF is the predominant term in balancing the incoming solar radiation in the tropical oceans; and

water vapor, aerosol, and clouds. The exclusion of strongly absorbing aerosols in GCMs can regionally cause excessive insolation at the ground (e.g., Cusack et al. 1998 ). The crude aerosol climatologies typically used in current GCMs and reanalyses do not properly account for these aerosol effects ( Wild 1999 ), thus introducing a bias not only in NSW radiation estimates, but also in, for example, the oceanic heat distribution ( Cai et al. 2006 ). c.
