摘要
Tropical dry 森林s (TDFs) have experienced pronounced droughts and increased temperatures for the last century. To assess whether these climatic shifts have influenced dry 森林 vegetation and ecosystem functioning, we integrated ground observations from a Costa Rican long-term 森林 dynamics monitoring plot with remotely sensed measures of 森林 productivity and canopy functioning from a diverse set of satellite data. Previously reported long-term 氣候 data (1921–1997) show a reduction in annual rainfall, but since 1980 there has been no directional change in mean annual precipitation. However, the 2015 El Nino Southern Oscillation (ENSO)-induced drought was unprecedented. Temperatures have increased by 1.1°C since 1931. However, the Landsat wet season (1987–2017) Enhanced Vegetation Index (EVI) (cano
