Peeling the onion in the Parliament. Like the onion, everything associated with Parliament has layers. As we make our way through the Parliamentary questions we discover more and more.
NIWA supply temperature data to the big overseas teams that maintain the global temperature datasets, including NASA, NOAA, the Hadley Centre, the WMO, NCDC and the UK Met Office (Hadley Centre).
It’s a bit odd that not all those organisations get the same sets of data.
For instance, the WMO gets monthly summaries comprising Kaitaia, Rotorua, Gisborne, New Plymouth, Paraparaumu, Kaikoura, Hokitika, Christchurch, Tara Hills, Invercargill, Raoul Island, Chatham Islands and Campbell Island — 13 stations in total.
From time to time, “Other data are provided in response to requests to NIWA.” So in August 2005, NCDC and NOAA reveived data from Kaitaia, Gisborne, New Plymouth, Paraparaumu, Hokitika, Tara Hills, Invercargill, Campbell Island, Chatham Islands and Raoul Island. That’s a bunch of 10 stations.
In August 2003, NIWA apparently sent (isn’t this fascinating?) the WMO data from 17 New Zealand sites: Kaitaia, Rotorua, Gisborne, New Plymouth, Napier, Paraparaumu, Nelson, Kaikoura, Hokitika, Christchurch, Tara Hills, Dunedin, Invercargill, Raoul Island, Chatham Island, Campbell Island and Scott Base, Antarctica. So that’s a New Zealand site?
In 1994, the UK Met Office (Hadley Centre) got temperature data for the seven-station series, plus Havelock North and Mt Cook (my emphasis).
Strange that in every case the overseas teams received data from more sites than we ourselves use for the national record.
Why does NIWA select only seven sites to describe the whole country? They really ought to explain it to us.
