Atmospheric analysis

New Zealand’s contribution to an ambitious international project aiming to generate a definitive map of the entire ocean floor in less than 12 years, is being launched in Wellington tomorrow.

Our climate is changing - we need to act now.

A pilot project has provided the most advanced mapping of a New Zealand lake ever and highlights the hazard to lakeside towns of tsunamis caused by landslides.

NZ River Maps is a simple, yet flexible, web-based tool that allows users to map and interrogate estimates for over 100 freshwater variables for the entire national river network.

ELFMOD is a statistical tool for estimating flows at multiple points along rivers subject to surface/ground-water exchanges, using both measured flow at selected sites and other predictor variables such as rainfall and groundwater levels.

EFSAP is a water planning and management tool designed to assist with setting regional or large-scale water resource use limits for rivers.

NIWA is encouraging farmers to plan for climate change so they can maximise their abilities to adapt and thrive as significant change begins to take place.

We've got hot temperatures, we've got cold temperatures, freezing temperatures, ice, snow, hail, rain - and even a few rays of sunshine. And one very confused weather pattern.

Our scientists provide the knowledge key for evidence-based decision-making and for our society as a whole.

On the bottom of New Zealand’s largest freshwater springs is an underwater garden of vivid green, pinks and inky blues.

Pupils at a Central Otago primary school are helping NIWA air quality scientists learn more about pollution in their town in a four-month project that will track where smoke comes from and where it goes over winter.
