Moving mode used for Ruppert Lake

500-yr running median

Low-frequency trends at Ruppert Lake were estimated using a moving mode, as opposed to a moving median, because this yielded a high signal-to-noise index. This difference was neglected in the current paper but is presented correctly and describe in more detail by Higuera et al. (2009):

Higuera, P. E., L. B. Brubaker, P. M. Anderson, F. S. Hu, and T. A. Brown. 2009. Vegetation mediated the impacts of postglacial climate change on fire regimes in the south-central Brooks Range, Alaska. Ecological Monographs 79:201-219.
