Atmospheric analysis

Short-term to long-term data estimation

A monthly summary of the climate in the tropical South Pacific islands, with an outlook for the coming months.

The High Performance Computing Facility (HPCF) is supercharging New Zealand science.

These datasets are available in a range of formats.

The Standardised Precipitation Index (SPI) is a simple measure of drought (and also of very wet conditions) and is based solely on the accumulated precipitation for a given time period.

Tuna or freshwater eels are a very significant, widely-valued, heavily-exploited, culturally iconic mahinga kai resource.

Northland, with its northern location, low elevation and close proximity to the sea is characterised by a mild, humid, and rather windy climate.

New Zealand has low-lying coastal areas that are vulnerable to inundation (flooding) by the sea.

Water clarity or turbidity is the cloudiness or haziness in a fluid caused by individual small particles (suspended solids).

Impacts of hydro-electric activities on water quality and mahinga kai.

The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.
