前辈~又来麻烦你一下哈~我在Global Change Biology看到的一篇文章《Modeling plant species distributions under future climates: how fine scale do climate projections need to be?》
他把275km分辨率的数据 统计降尺度到90m!!! 请问这样弄科学吗???
文章摘录:These coarse-scale (275 km) grids of projected climate ere first statistically downscaled to 12 km resolution using the ethod of constructed analogs (Hidalgoet al., 2008). They were then spatially downscaled from 12 km with digital elevation grids to four resolutions: 4218 m (hereafter ‘4 km’), 800, 270,and 90 m. The data were first downscaled to 4 km and bias corrected using historical climate data for 1950–2000 available for the USA from PRISM (Dalyet al., 1994) as monthly maps (http://www.prism.oregonstate.edu/).
