Fine‐scale spatial climate variation fosters biodiversity and buffers it from change, but ecological studies are constrained by the limited accessibility of relevant fine‐scale data. In this paper we introduce a novel form species distribution model that uses occurrences to predict high‐resolution variation. This new category ‘bioclimate' data, representing micro‐scale as experienced one or more interest, is useful complement microclimate data existing approaches. The modeling method, called BISHOP for ‘bioclimate inference species' occurrence patterns,' on occurrences, coarse‐scale climate, physiography (e.g. terrain, soil, vegetation) triangulate bioclimate patterns. It works pairing climate‐downscaling function predicting latent variable, with niche bioclimate. infers how affects bioclimate, estimates these effects vary geographically, produces (10 m) maps over large regions. also predicts distributions. After introducing approach, apply in an empirical study focused topography trees. Using 216 North American tree species, document biogeographic patterns enable BISHOP, estimate four terrain variables (northness, eastness, windward exposure, elevational position) each influence three variables, use results produce downscaled tree‐specific Model validation demonstrates inferred outperforms macroclimate distributions separate not used during inference, confirming its relevance. Our show nearby bioclimates can differ 5°C temperature twofold moisture, equator‐facing, east‐facing, windward‐facing, locally elevated sites exhibiting hotter, drier average. But greatly across zones, revealing topographically similar landscapes strongly their These have important implications micrometeorology, biodiversity, resilience.
