A simple yellow sign at Lauder on State Highway 85, 35km from Alexandra, marks the turn-off to the National Institute of Water and Atmospheric research station.
This inconspicuous rural setting is home to a facility with an international reputation and multi-million dollar equipment which is helping scientists around the world predict future climate change.
As Niwa principal scientist Richard McKenzie says: "Although your average New Zealander wouldn't have the foggiest idea where Lauder is, your average atmospheric physicist around the world knows Lauder better than they know Auckland or Christchurch."
The research institute celebrates a special milestone this month - its 50th birthday.
Lauder's clear skies and isolation made it a perfect site for observing and testing the atmosphere. Right from its early days, the station's staff were carrying out research that gained international prominence.
In the lead-up to the station's 50th anniversary celebrations next week, the Otago Daily Times today takes a closer look at the history and the contribution made by the station over the years.
