Abstract. The core version of the Norwegian Climate Center's Earth System Model, named NorESM1-M, is presented. NorESM family models are based on Community Model 4 (CCSM4) University Corporation for Atmospheric Research, but differs from latter by, in particular, an isopycnic coordinate ocean model and advanced chemistry–aerosol–cloud–radiation interaction schemes. NorESM1-M has a horizontal resolution approximately 2° atmosphere land components 1° ice components. also available lower...
We present a new surface-atmospheric dataset for driving ocean–sea-ice models based on Japanese 55-year atmospheric reanalysis (JRA-55), referred to here as JRA55-do. The JRA55-do aims replace the CORE interannual forcing version 2 (hereafter called dataset), which is currently used in framework of Coordinated Ocean-ice Reference Experiments (COREs) and Ocean Model Intercomparison Project (OMIP). A major improvement refined horizontal grid spacing ( ∼ 55 km) temporal interval (3 hr). data...
The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 based on Community (CESM2) shares with CESM2 computer code infrastructure many system model components. However, employs entirely different ocean biogeochemistry models. atmosphere component (CAM-Nor) includes a module for aerosol physics chemistry, including interactions cloud radiation; additionally, CAM-Nor improvements in formulation local dry moist energy conservation, global...
Abstract. NorESM is a generic name of the Norwegian earth system model. The first version named NorESM1, and has been applied with medium spatial resolution to provide results for CMIP5 (http://cmip-pcmdi.llnl.gov/cmip5/index.html) without (NorESM1-M) (NorESM1-ME) interactive carbon-cycling. Together accompanying paper by Bentsen et al. (2012), this documents that core NorESM1-M valuable global climate model research providing complementary evaluation possible anthropogenic change. based on...
Abstract. The recently developed Norwegian Earth System Model (NorESM) is employed for simulations contributing to the CMIP5 (Coupled Intercomparison Project phase 5) experiments and fifth assessment report of Intergovernmental Panel on Climate Change (IPCC-AR5). In this manuscript, we focus evaluating ocean land carbon cycle components NorESM, based preindustrial control historical simulations. Many observed large scale biogeochemical features are reproduced satisfactorily by NorESM. When...
Abstract. We present a new framework for global ocean–sea-ice model simulations based on phase 2 of the Ocean Model Intercomparison Project (OMIP-2), making use surface dataset Japanese 55-year atmospheric reanalysis driving models (JRA55-do). motivate OMIP-2 over first OMIP (OMIP-1), previously referred to as Coordinated Ocean–ice Reference Experiments (COREs), via evaluation OMIP-1 and from 11 state-of-the-science models. In evaluation, multi-model ensemble means spreads are calculated...
Abstract. The ocean carbon cycle is a key player in the climate system through its role regulating atmospheric dioxide concentration and other processes that alter Earth's radiative balance. In second version of Norwegian Earth System Model (NorESM2), oceanic component has gone numerous updates include, amongst others, improved process representations, increased interactions with atmosphere, additional new tracers. Oceanic dimethyl sulfide (DMS) now prognostically simulated fluxes are...
The mid-Piacenzian climate represents the most geologically recent interval of long-term average warmth relative to last million years, and shares similarities with projected for end 21(st) century. As such, it a natural experiment from which we can gain insight into potential change impacts, enabling more informed policy decisions mitigation adaptation. Here, present first systematic comparison Pliocene sea surface temperature (SST) between an ensemble eight model simulations produced as...

Abstract. The carbon cycle is a major forcing component in the global climate system. Modelling studies, aiming to explain recent and past climatic changes project future ones, increasingly include interaction between physical biogeochemical systems. Their ocean components are generally z-coordinate models that conceptually easy use but employ vertical coordinate alien real structure. Here, we present first results from newly-developed isopycnic model demonstrate viability of using an for...
In this paper we compare the simulated Arctic Ocean in 15 global ocean–sea ice models framework of Coordinated Ocean-ice Reference Experiments, phase II (CORE-II). Most these are ocean and sea-ice components coupled climate used Coupled Model Intercomparison Project Phase 5 (CMIP5) experiments. We mainly focus on hydrography interior, state Atlantic Water layer heat volume transports at gateways Davis Strait, Bering Fram Strait Barents Sea Opening. found that there is a large spread...
Abstract. The mid-Pliocene period (3.3 to 3.0 Ma) is known as a warm climate with atmospheric greenhouse gas levels similar the present. As at this time was in equilibrium forcing, it valuable test case better understand long-term response high of gases. In study, we use low resolution version Norwegian Earth System Model (NorESM-L) simulate pre-industrial and climate. Comparison simulation observations demonstrates that NorESM-L simulates realistic simulated global mean surface air...
Abstract. Idealised and hindcast simulations performed with the stand-alone ocean carbon-cycle configuration of Norwegian Earth System Model (NorESM-OC) are described evaluated. We present simulation results three different model configurations (two versions at grid resolutions) using two atmospheric forcing data sets. version NorESM-OC1 corresponds to that is included in NorESM-ME1 fully coupled model, which participated CMIP5. The main update between NorESM-OC1.2 addition new options for...
We document a pilot stochastic re-analysis computed by assimilating sea surface temperature (SST) anomalies into the ocean component of coupled Norwegian Climate Prediction Model (NorCPM) for period 1950–2010 (doi: 10.11582/2016.00002). NorCPM is based on Earth System and uses ensemble Kalman filter data assimilation (DA). Here, we assimilate SST from HadISST2 historical reconstruction. The accuracy, reliability drift are investigated using both assimilated independent observations. slightly...
