In this presentation, I use six temperature data sets over Arctic Ocean areas to examine the following research questions:
- Are there significant differences in Arctic temperatures among the data sets? If so, which data sets are statistically different and over what areas?
- Are there significant differences in the trend of Arctic temperatures among the data sets? If so, which data sets are statistically different and over what areas?
- Do variations in temperatures among the data sets lead to significantly different modeled ice thickness distributions?
Discussion of the results will show that there are noticeable differences among all of the datasets, and no two datasets are statistically indistinguishable for all months. Spatially, the largest differences in temperature are centered on areas of the marginal ice zone. For trend analyses, some datasets show warming and some show cooling in the eastern Arctic, and the differences in the data sets lead to significant differences in modeled ice thickness.
