Graphs showing predicted and measured UV Index at Lauder are updated at 15 minute intervals. Unlike the UVI predictions seen on TV, these include the effects of clouds. The most recent UVI is displayed, along with a corresponding behavioural message. These messages correspond to five intensity ranges, as recommended by Sunsmart and the Cancer Society of New Zealand. We plan to make similar data from other sites available in this way at a later date but currently data are downloaded from most instruments elsewhere only once per day.

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.

The maps provided here are forecasts modelled on available satellite ozone data.

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 predicted and measured UV Index at Leigh, Paraparaumu, Christchurch, Lauder, Invercargill and Rarotonga are updated daily.

Measurements of inorganic ion composition of monthly/fortnightly rainfall samples collected at Kelburn, Lauder, Puruki. Measurement locations and dates are given below: Kelburn (41.17° S, 174.46° E) from March 1983 to March 1992 Lauder (45.02° S, 169.41° E) from July 1982 to Oct 1993 Puruki (38.43° S, 176.22° E) from July 1989 to Feb1991

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.
