CATALOGUE OF CLIMATOLOGICAL DATA FROM NEW ZEALAND STATIONS IN ANTARCTICA

STATION INFORMATION

Scott Base (77.85S, 166.80E, altitude 16 m) has been continuously inhabited since the 1957 International Geophysical Year. The station, which is about 3 km away from the Untied States McMurdo Station, is situated at the southern end of Hut Point Peninsula, Ross Island in McMurdo Sound. The surface around Scott Base is mainly volcanic scoria. Snow cover is variable, and during the summer the ground is primarily snow-free.

Synoptic and climatological weather observations commenced at Scott Base on 28 February 1957; observations were made at 0000, 0600, 1200, and 1800 UTC. From 31 January 1960 until 30 September 1964 the observations were only made at 0000 and 1200 UTC. The synoptic observations cased on 30 September 1964. The climatological observations have continued; they were made at 0000 UTC from 1 October 1964 until 31 October 1965, and at 2100 UTC from 1 November 1965 onwards.

Trace gas measurements, which are described in the "Atmospheric Composition" section are made form the Arrival Heights laboratory, which is 5 km away from Scott Base.

Vanda Station (77.52S, 161.67E, altitude 94m) was established by the New Zealand Antarctic Division on the south-east shore of Lake Vanda in 1967. Vanda Station is in the Wright Valley, which is relatively ice-free and forms part of the Dry Valley system.

A full meteorological observign programme was made at the site for the three full years 1969, 1970 and 1974, and all the summer seasons (i.e. late October to late January) from 1968 through to 1990. Measurements made at Vanda included three-hourly synoptic observations, solar radiation, wind and temperature.
