    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 High Intensity Rainfall Design System is a web-based programme that can estimate rainfall frequency at any point in New Zealand. It can be used to estimate rainfall depths for hydrological design purposes, and to assess the rarity of observed storm events.

    The aim of the UV Atlas project is to produce maps and time series of parameters describing the UV radiation environment over New Zealand since 1960. Maps are produced for the area around New Zealand (34° to 48°S, 166° E to 180°) while time series are produced at sites where broadband radiation measurements are available.
