1. Net ecosystem gas exchange (NEE), a balance between gross ecosystem primary productivity (GPP) and ecosystem respiration (ER), is an important indicator of terrestrial ecosystem CO2 sink or source. Increasing frequency of droughts during different periods of the growing season may affect terrestrial ecosystem carbon balance. However, detecting how drought timing controls ecosystem carbon processes is insufficiently explored because it is a challenge to accurately monitor and forecast drought dynamics. 2. In a five-year (2015-2019)...
