Increased atmospheric vapor pressure deficit
WebDec 17, 2024 · Our model also accounts for changes in atmospheric vapor pressure deficit (VPD), which we modeled following Murray : VPD = 611 × e 17.502 × Ta Ta + 240.97 − 611 × e 17.502 × Td Td + 240.97 (1) where T a is the average daily temperature in degrees Celsius and T d is the dew point obtained from MERRA2. WebEarth is currently undergoing a global increase in atmospheric vapor pressure deficit (VPD), a trend which is expected to continue as climate warms. This phenomenon has been associated with productivity decreases in ecosystems and yield penalties in crops, with these losses attributed to photosynthetic limitations arising from decreased ...
