Effects of precipitation and temperature on precipitation use efficiency of alpine grassland in Northern Tibet, China [PDF]

open access: yesScientific Reports, 2020
AbstractPrecipitation use efficiency (PUE) is crucial in understanding the coupling between ecosystem carbon and water cycling. In this study, we used a time series (2000–2013) dataset of net primary productivity (NPP) based on the Carnegie–Ames–Stanford Approach (CASA) model together with precipitation to reveal the spatial and temporal patterns of ...
