Atmospheric analysis

An overview of Science at NIWA

Hull-mounted on the RV Tangaroa, the EM302 multibeam echosounder maps the seafloor using a fan of 288 acoustic beams, producing up to 864 soundings per ping in dual swath mode, providing 100% coverage of the seabed.

NIWA maintains the national climate database for New Zealand, and can supply data in a variety of ways.

The Intergovernmental Panel on Climate Change (IPCC) is charged with assessing the most up to date scientific, technical and socio-economic research on climate change.

Because of its exposure to disturbed weather systems from the Tasman Sea, this climate zone is often quite windy, but has few climate extremes.

This lesson will explore the use of Māori environmental indicators [tohu] to anticipate local weather and climate conditions.

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

All transmissions from GMS-5 are no longer received at NIWA’s satellite reception station in Wellington. We are working on an alternative data feed and will be able to bring back these images later this year. Once we start receiving data again, it will then be calibrated, re-mapped onto standard map projections, and archived.

The land used to produce crops is usually flat to gently rolling so it can be tilled, sowed, and harvested.

The current method for calculating wind speed-up is inadequate, and can grossly under-predict correct design wind speeds in NZ's complex terrain.
