Abstract Cloud radiative kernels (CRK) built with transfer models have been widely used to analyze the cloud effect on top of atmosphere (TOA) fluxes, and it is expected that CRKs would also be useful in analyses surface which determines regional temperature change variability. In this study, at TOA were using Rapid Radiative Transfer Model (RRTM). Longwave (CRE) primarily driven by base proper...

Our aim is to provide an observational reference for the evaluation of the surface and boundary layer parameterizations used in large-scale models using the remarkable long-term Canadian Prairie hourly dataset. First we use shortwave and longwave data from the Baseline Surface Radiation Network (BSRN) station at Bratt’s Lake, Saskatchewan, and clear sky radiative fluxes from ERA-Interim, to sho...

This study investigates the extent to which assimilating high-resolution remotely sensed cloud cover into the Regional Atmospheric Modeling System (RAMS) provides an improved regional diagnosis of downward shortand longwave surface radiation fluxes and precipitation. An automatic procedure was developed to derive highresolution (4 km 3 4 km) fields of fractional cloud cover from visible band Ge...

We examine 800-year time series of internally generated variability in both a coupled ocean-atmosphere model where water vapor anomalies are not allowed to interact with longwave radiation and one where they are. The ENSO-like phenomenon in the experiment without water vapor feedback is drastically suppressed both in amplitude and geographic extent relative to the experiment with water vapor fe...

The radiative constraints on the partitioning of the surface energy budget and, hence, on the strength of the hydrological cycle are analyzed in an idealized one-dimensional radiative–convective equilibrium model formulated in terms of the energy budgets at the top of the atmosphere, the subcloud layer, and the free atmosphere, which enables it to predict both surface relative humidity and the ...

Abstract Simulations of the global climate system at storm-resolving resolutions 2 km are now becoming feasible and show promising realism in clouds precipitation. However, shortcomings their representation microscale processes, like interaction cloud droplets ice crystals with radiation, can still restrict utility. Here, we illustrate how changes to microphysics scheme dramatically alter both ...

In this paper, time extension methods, originally designed for clear-sky land surface conditions, are used to estimate high-spatial resolution daily longwave (LW) radiation from the instantaneous Global LAnd Surface Satellite (GLASS) product. The performance of four methods were first tested by using ground based flux measurements that collected 141 global sites. Combined with accuracy LW estim...

Using two versions of the GFDL coupled ocean-atmosphere model, one where water vapor anomalies are allowed to affect the longwave radiation calculation and one where they are not, we examine the role of water vapor feedback in internal precipitation variability and greenhouse-gas-forced intensification of the hydrologic cycle. Without external forcing, the experiment with water vapor feedback p...
