On the Use of ARM Data in the Validation and Refinement of a GCM Radiation Parameterization Scheme
نویسندگان
چکیده
Data provided under the Atmospheric Radiation Measurement (ARM) Program of the U.S. Department of Energy have been analyzed with the goal of evaluating a radiation parameterization scheme currently used in both cloud resolving models and general circulation models (GCMs). These evaluations are also used to develop refinements to the parameterization scheme, and the performance of the climate model has been assessed with these refinements. The specific areas examined include (1) cloud overlap, (2) in-cloud horizontal inhomogeneity, and (3) broadband fluxes and heating rates.

Evaluation of NASA GISS Post-CMIP5 Single Column Model Simulated Clouds and Precipitation Using ARM Southern Great Plains Observations
The planetary boundary layer turbulence and moist convection parameterizations have been modified recently in the NASA Goddard Institute for Space Studies (GISS) Model E2 atmospheric general circulation model (GCM; post-CMIP5, hereafter P5). In this study, single column model (SCM P5) simulated cloud fractions (CFs), cloud liquid water paths (LWPs) and precipitation were compared with Atmospher...

[1] The mosaic approach of Liang and Wang (1997) for the general circulation model (GCM) parameterization of subgrid cloud-radiation interactions is evaluated against the validated cloud-resolving model (CRM) simulation of the Atmospheric Radiation Measurement (ARM) intensive observation period (IOP, June 22–July 17, 1997) at the Southern Great Plains (SGP) site. The CRM-generated cloud statist...
متن کاملEffect of Cloud Overlap and Inhomogeneity on Climate Simulations
Atmospheric radiation budgets are strongly affected by the horizontal and vertical distributions of cloud systems. With the horizontal resolution of several hundred kilometers in general circulation models (GCMs), parameterization of cloud vertical overlap and horizontal inhomogeneity in radiation schemes has long been a major challenge for climate simulations (Stephens 1984; Stephens et al. 20...

Introduction: Due to importance of data quality, issues relating to filling the missing data has found a great deal of interest. Regeneration methods for missing data can be classified into two kinds of classical and modern categories. Application of statistical methods such as relationship with nearby stations and approaches on the base of hydrological, climatological or physiographical simila...
