Evaluating models for predicting microclimates across sparsely vegetated and topographically diverse ecosystems
Aim: Microclimate information is often crucial for understanding ecological patterns and processes, including under climate change, but is typically absent from ecological and biogeographic studies owing to difficulties in obtaining microclimate data. Recent advances in microclimate modelling, howev...
