    Towards process-informed bias correction of climate change simulations

    Biases in climate model simulations introduce biases in subsequent impact simulations. Therefore, bias correction methods are operationally used to post-process regional climate projections. However, many prob...

    Assimilating continental mean temperatures to reconstruct the climate of the late pre-industrial period

    An on-line, ensemble-based data assimilation (DA) method is performed to reconstruct the climate for 1750–1850 AD, and the performance is evaluated on large and small spatial scales. We use a low-resolution ve...

    Delayed Holocene warming

    Remnants of the Laurentide ice sheet lasted until about 7,000 years ago. Climate simulations show that they caused the multimillennial delay between maximum early Holocene solar radiation and temperatures evid...

    Transient simulations, empirical reconstructions and forcing mechanisms for the Mid-holocene hydrological climate in southern Patagonia

    This study investigates the atmospheric circulation in transient climate simulations with a coupled atmosphere–ocean general circulation model (GCM) for the mid-Holocene (MH) period 7–4.5 ka BP driven with com...

    Early peak in Antarctic oscillation index

    The principal extratropical atmospheric circulation mode in the Southern Hemisphere, the Antarctic oscillation (or Southern Hemisphere annular mode), represents fluctuations in the strength of the circumpolar ...

    Reconstructing Large-scale Variability from Palaeoclimatic Evidence by Means of Data Assimilation Through Upscaling and Nudging(DATUN)

    This chapter describes a newly developed approach for extracting the climate signal from proxy records, termed DATUN (Data Assimilation Through Upscaling and Nudging).
