The all-sky image shows a hemispheric view of the sky at Lauder. The band extending from the center of the image to the edge shields the camera from the direct sun which would otherwise cause blooming on the image and obscure the details of the clouds. These images record the cloud cover at Lauder for use in the atmospheric radiation research. Post-processing of the images is used to determine cloud cover, area to edge ratios, and so on. The images are updated every 10 minutes and an archive image is available for each of the last 24 hours.

Broadband erythemal UV irradiances measured at 10 minute intervals at 5 sites in New Zealand. Short wave direct, diffuse, and global radiation at Lauder. Network of approximately 70 national climate database radiation sites in the New Zealand region with broadband short wave radiation, and four higher quality sites with diffuse, direct, and global irradiances.

Graphs showing UVI forecasts specific sites in New Zealand and the South Pacific region. When the UVI is low (less than 3), no protection is required and short exposures to sunlight will be beneficial for vitamin D production. At all other times some protection to avoid sunburn is recommended. The "UV Alert Period" is defined as the period when the clear sky UVI forecast is greater than 3. When the UVI is 3, damage to fair skin can occur in less than 1 hour. When the UVI is 12, damage to fair skin can occur in less than 15 minutes. For darker Polynesian skin types the safe exposure periods can be doubled.

Database of direct measurements Balloon-borne ozonesonde flights, microwave radiometer measurements, and ozone lidar measurements, made from Lauder (45.04oS, 169.68oE), New Zealand. Archives of the measurements are maintained at NIWA, Lauder, and in various international data archives. A combined data set of satellite-based vertical ozone profile measurements is maintained at NIWA using measurements from a variety of satellite-based instruments including SAGE I, SAGE II, SAGE III, ILAS I, ILAS II, HALOE, POAM II, POAM III, GOMOS, MIPAS, SCIAMACHY, OSIRIS.

The concentration and isotopic composition of greenhouse gases and related species are measured in-situ or by discrete collections at the surface at Baring Head, Wellington (41.42ºS, 174.87ºE); Arrival Heights, Antarctica (77.80ºS, 166.67ºE); and Lauder, Central Otago (45.03ºS, 169.67ºE). These data contribute to the information managed by the World Data Centre for Greenhouse Gases (WDCGG).
