TL;DR: In this paper, the authors evaluated four currently available reanalysis models using data from the North Slope of Alaska (NSA) Barrow site of the Atmospheric Radiation Measurement Program (ARM).

TL;DR: A new monthly 1° × 1° Antarctic near-surface temperature reconstruction for 1960-2005 is presented in this article, which uses numerical model fields to establish spatial relationships between fifteen continuous observational temperature records and the voids to which they are interpolated inherently accounts for the effects of the atmospheric circulation and topography on temperature variability.

TL;DR: In this paper, the authors assess strategies for providing regional projections based on global climate models using the high-latitude Northern Hemisphere as a focus, using a set of model results obtained from an "ensemble of opportunity".

TL;DR: In this paper, atmospheric pressure data are used to show that the local forcing of high-latitude North Atlantic Ocean fluctuations is augmented by antecedent atmospheric circulation anomalies over the central Arctic.

TL;DR: In this article, the Community Climate System Model, version 4 (CCSM4) is evaluated against observational and reanalysis datasets for the present-day (1981-2005) to evaluate surface air temperature, sea level pressure, cloud cover and phase, precipitation and evaporation, atmospheric energy budget, and lower-tropospheric stability.
