About the Weather Station
Purpose
The weather station is maintained and managed by the Energy Studies
Programme at the Department of Physics for the purposes of obtaining
meteorological data specific to the University of Otago campus.
Measurement and analysis of climatic conditions is essential for
the assessment of the viability of renewable energy generation options
such as solar panels and wind turbines, and to assess the thermal
performance of buildings. Hence the data collected by the Energy
Studies Weather Station is useful for various research projects
being carried out onsite currently, and those that may be carried
out sometime in the future, as well as for teaching laboratories
and the interest of the general public.

Environment
Dunedin is located in the south-east of the South Island of New
Zealand, built on the coast around Otago Harbour, adjacent to the
Otago Peninsula. The New Zealand Metservice maintains two weather
stations in Dunedin, one located in Musselburgh in the south of
the city, and one at Momona Airport, inland from the city. Dunedin
North, where the Energy Studies Weather Station is situated, often
experiences slightly different conditions compared to these sites
because of the influence of the surrounding hills.

Notes
If you would like to bookmark the weather station display directly

The weather station window is set to automatically refresh every
five minutes in order for the latest weather data to be displayed.
Cached data is set to expire after two and a half minutes.
The time given on the display is New Zealand Day Time (NZDT).
This is 12 hours later than Universal Time (NZDT = UTC + 12 hrs),
except during daylight savings when it is 13 hours later (NZDT =
UTC + 13 hrs). Daylight savings in New Zealand is from the first
Sunday in October to the third Sunday in March. Graphed data in
the online display will be overlapped or stretched by one hour on
daylight savings change-over days.
