This research will evaluate recent variations of surface air temperature over the Arctic and subarctic through consolidation and comparison of existing data on Arctic surface air temperature from high-latitude land stations, Arctic Ocean ice stations and from sub-arctic sea surface temperatures. These data will be examined for evidence of changes consistent with model projections of greenhouse warming, which has been shown to be amplified in polar regions during the non-summer months. The dataset will span the past several decades, 1950 to present, and will cover the region pole-ward of 45 degrees north latitude. The study will also assess the magnitude of the urbanization effect at northern land stations. This research is collaborative with DPP 9214793.

这项研究将通过整合和比较来自高纬度陆地站、北冰洋冰站和亚北极海面温度的现有北极表面气温数据，评估北极和亚北极表面气温的近期变化。将检查这些数据，寻找与温室变暖模型预测一致的变化证据，事实证明，在非夏季月份，极地地区的变暖现象会加剧。 该数据集将跨越过去几十年，从1950年至今，并将覆盖北纬45度极地地区。 该研究还将评估北部陆地站城市化影响的程度。 这项研究是与 DPP 9214793 合作的。
