Frequency histograms of time lags for different vegetation types.

Histograms represent pixel proportions at various time lags from 0–12 months for different vegetation types to precipitation (PRE) (a), shortwave radiation (SWD) (b) and temperature (TMP) (c), and a cumulative frequency map for different vegetation types combining Figs a-c (d). F refers to tropical rainforest of evergreen broadleaf forest; S refers to savanna.
