The purpose of this study is to evaluate the historical simulated internal variability of Arctic sea ice in climate models. Determining model realism is our best tool to have confidence in the projected internal variability of these models. Internal variability, and therefore the spatial and temporal distribution of sea ice conditions, is essential to a range of stakeholders. We find that, in general, models agree well with observations, but as no model is within observational uncertainty for all months and all locations, model selection is highly important. Furthermore, we highlight that model consistency is often achieved due to large observational uncertainty.

An internal UK Met Office report produced during a summer internship (June-August 2018). Analysis of radiosonde descent data from 6 diverse sites and collaboration with ECMWF for background model comparisons. Findings showed a vast majority of descent data has sufficiently low biases to warrant further investigation for assimilation into operational model analyses.
