Spatial resolution of climate extraction #13

Closed dmcglinn closed 7 years ago

dmcglinn commented 9 years ago

Hey @ejforrestel @dschwilk @Carolin3L @SallyArchibald, do any of you have a strong preference for the spatial resolution that we extract the climate data at. It is available from WorldClim http://www.worldclim.org/current by default at five resolutions: 30 arc sec, 2.5 arc min, 5 arc min, and 10 arc min. My sense is that finer res climate interpolations have more error at the higher res, but at the coarse res you sacrifice site scale heterogeneity so it is a tradeoff what resolution you use. For the freezing paper with @AmyZanne we used 5 arc minute. If I don't hear from others I'll just use that again.

5 arc minute seems to be the standard so I say go for it.

Thanks, Dan!

Best, Beth

5 Arcmin sounds fine.
