资源简介：
Dynamic variables were available on a monthly basis. As the variables differed in their spatial resolutions, they were aggregated to match a standard grid with cell size of 0.04°. Spatial gradients were estimated as their proportional change (PC) within a surrounding 3×3 cell (0.75°×0.75°) grid using a moving window as follows: PC = ((maximum value – minimum value)×100)/(maximum value).
