An Arctic Temperature Data Base and Trend Assessment

这项研究将评估最近的地表空气变化 在北极和亚北极温度通过巩固 北极地面气温现有数据的比较 从高纬度的陆地观测站，北冰洋的冰站， 从亚北极海表面温度。这些数据将 检查与模型一致的变化证据 温室效应的预测，这已被证明是 在非夏季的几个月里在极地地区被放大。 的 数据集将跨越过去几十年，1950年至今， 将覆盖北纬45度的极地地区。 该研究还将评估城市化的规模， 在北方陆地站的影响。 这项研究是合作的 DPP 9214793。

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.
