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...
متن کاملInteractive comment on “Towards a better representation of the solar cycle in general circulation models” by K. M. Nissen et al
Reply to Referee #4: General comments: The Referee suggests a comparison of the ECHAM5-MESSy simulations using the FUBRad scheme with other GCM or CCM simulations. This is however beyond the scope of this paper. A radiation code intercomparison is going to be performed within the CCMVal activity. FUBRad will participate in this intercomparison. The Referee is right when stating that other GCMs/...
متن کاملOn the Use of ARM Data in the Validation and Refinement of a GCM Radiation Parameterization Scheme
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 mo...
متن کاملTreatment of Cloud Radiative Effects in General Circulation Models (GCMs): Cloud Overlap Effects on GCM Climate Simulations
We participate in the Atmospheric Radiation Measurement (ARM) Program with two objectives: 1) to improve general circulation model (GCM) cloud/radiation treatment with focus on cloud vertical overlapping and layer cloud optical properties, and 2) to study the effects of cloud-radiation climate interaction on GCM climate simulations. This report summarizes the recent findings in sub-grid scale v...
متن کاملStronger Security Variants of GCM-SIV
At CCS 2015, Gueron and Lindell proposed GCM-SIV, a provably secure authenticated encryption scheme that remains secure even if the nonce is repeated. While this is an advantage over the original GCM, we first point out that GCM-SIV allows a trivial distinguishing attack with about 248 queries, where each query has one plaintext block. This shows the tightness of the security claim and does not...
