Atmospheric analysis

Commercial eel fishery in New Zealand began in earnest in the 1960s and expanded rapidly until the early 1970s

New Zealand’s forests and other land areas may be absorbing up to 60% more carbon dioxide than has been calculated, with much of this uptake likely occurring in native forests, NIWA scientists have discovered.

Most of this climate zone is characterised by cool coastal breezes, and absence of shelter from the unsettled weather that moves over the sea from the south and southwest. Hot northwesterly conditions in summer can occasionally bring high temperatures. Typical summer daytime maximum air temperatures range from 16°C to 23°C, occasionally rising above 30°C. Winters are cold with infrequent snowfall and frequent frost. Typical winter daytime maximum air temperatures range from 8°C to 12°C.

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.
