    Maps of the average first and last dates of soil moisture deficit are shown here.
  • Generating synthetic wind data

    Research Project
    NIWA has recently created synthetic, multi-year, 10-minute wind datasets at 15 wind farm sites across New Zealand. These will be used by the Electricity Commission to model the impact of wind farms on the national grid.
  • Dry stock

    Dry stock farming consists predominantly of pasture grazing beef cattle, sheep, and deer for meat, wool, and velvet production.
