This paper documents the version 1 of the Finite-volume Atmospheric Model of the IAP/LASG (FAMIL1),which has a flexible horizontal resolution up to a quarter of a degree.The model,currently running on the "Tianhe 1A" supercomputer,is the atmospheric component of the third-generation Flexible Global Ocean–Atmosphere–Land climate System model (FGOALS3) which will be used to participate in the Coupled Model Intercomparison Project Phase 6 (CMIP6).In addition to describe the FAMIL1 dynamical core and physical parameterizations,this paper describes the simulated characteristics of energy and water balances and their comparisons with observations.The comparisons indicate that the model simulates well the seasonal and geographical distributions of radiative fluxes at the top of the atmosphere and on the surface,as well as the surface latent and sensible heat fluxes.A major weakness in the energy balance is identified in the regions where extensive and persistent marine stratocumulus present.Analysis of the global water balance also indicates realistic seasonal and geographical distributions with the global annual mean of evaporation minus precipitation approximately 10 -4 mm day -1.Finally,the model biases as well as possible solutions are discussed.
