Potential Evapotranspiration (PET)

This page shows Potential Evapo-Transpiration (PET) figures recorded for relevant climate sites scattered around the Hawke's Bay region. PET data is collected using a Li-Cor Pyranometer. Total PET is calculated using the commonly used Penman-Monteith equation. Units are measured in mm.

Hawke's Bay Regional Council measures meteorological information at several climate stations across Hawkes Bay.

The parameters monitored vary from site to site, but will normally include air temperature, humidity, rainfall, wind speed and wind direction. Several sites also measure soil moisture, soil temperature, solar radiation and PET  (what exactly is PET).

Data from the climate monitoring sites throughout the region are telemetered to the Hawkes Bay Regional Council office twice a day.

The information collected is vital for flood warning purposes, water management during drought, and detecting long-term trends in climate.

Cricklewood climate station, located in Northern Hawke`s Bay.

The climate stations are calibrated on an annual basis (usually September each year), and are regularly maintained by Council staff. 

Additional climate data is also available from NIWA`s CliFlo website which provides access to the National  Climate Database.  Climate data accessed through CliFlo is now free by subscribing on-line, and is subject to NIWA�s terms and conditions of use.

Acknowledgement

The Hawkes Bay Regional Council own and operate the climate station network in partnership with several other organisations, and would like to acknowledge Bay Forests Rural Fire District, Hastings District Rural Fire Authority, Rangitikei District Council, and Central Hawke`s Bay District Council.
