Mean Annual Vapour Pressure Deficit (VPDYR)

02 Oct 2012

This dataset was first added to LRIS Portal on 02 Oct 2012.

A 25m resolution grid of mean vapour pressure deficit derived from the Land Environment New Zealand underlying climate dataset at an original resolution of 100m. This grid was resampled to 25m by bilinear interpolation to have visually compatible resolution to other data sets being used in modelling of BASE carrying capacity. For use with both Model 1 and Model 2.

Vapour pressure deficit (VPD) is the meteorological variable used to quantify the drying power of the atmosphere. The VPD estimates the difference (or gradient) in vapour pressure
(concentration of water vapour) between the moist vegetation and the drier atmosphere above.

Moderate VPD is beneficial to plants, helping to drive photosynthetic processes, but extreme
and/or prolonged high VPD will stress plants and negatively effect productivity.
