    UV measurement - Lauder

    UVI at Lauder

    This information is provided as part of our UV Ozone service, which also includes ozone and UV maps for New Zealand, yesterday’s forecast and measured UV, UV Atlas software, and more. NIWA has also developed an instrument to measure UV levels and display the UV Index on an easy-to-read dial. This is intended for use at swimming pools, outdoor sports events, and so on. The measured UV Index can be affected by cloud cover at Lauder.
