This document describes the climate of version 1 of the NASA-NCAR model devel-oped at the Data Assimilation Office (DAO). The model consists of a new finite-volume dynamical core and an implementation of the NCAR climate community model (CCM-3) physical parameterizations. The version of the model examined here was integrated at a resolution of 20 latitude by 2.50 longitude longitude and 32 levels. The results are based on a simulation that was forced with observed sea surface temperature and sea ice for the period 1979-1995, and are compared with NCEP/NCAR reanalyses and various other observational data sets. The results include an assessment of seasonal means, subseasonal transients including the Madden Julian Oscillation, and interan-nual variability. The quantities include the zonal and meridional winds, temperature, specific humidity, geopotential height, stream function, velocity potential, precipitaion, sea level pressure, and cloud radiative forcing.
