TL;DR: In this paper, the 2D zonal atmospheric model, ZAM2, has been used to test Charney's hypothesis that high desert albedo initiates a biogeophysical positive feedback response by the atmosphere and the results agree with the earlier test in the NASA GISS 3D GCM model (Charney et al. 1975) in confirming a positive feedback through precipitation but indicate a negative feedback in terms of temperature.

TL;DR: In this paper, the authors focus on the activities related to the initial set of satellite observations, which are being carried out in close coordination with CMIP5 and directly engage NASA's observational (e.g., mission and instrument) science t...

TL;DR: In this paper, the authors introduce the Frequent Rainfall Observations on GridS (FROGS) database, which is composed of gridded daily-precipitation products on a common grid to ease intercomparison and assessment exercises.

TL;DR: In this paper, the Community Atmospheric Model 2 (CAM2) is run as a short-term forecast model initialized with reanalysis data, and the intent is to reveal model deficiencies before complex interactions obscure the root error sources.

TL;DR: In this article, seasonal changes in cloud-radiative forcing (CRF) at the top of the atmosphere from 18 atmospheric general circulation models, and observations from the Earth Radiation Budget Experiment (ERBE) were compared.
