We record rainfall at 82 sites throughout Canterbury, measuring intensities in 7.5 or 15-minute intervals depending on the site’s proximity to the Southern Alps/Kā Tiritiri o te Moana, and report it alongside data measured by partner agencies at 11 other sites. Data can be used to assess storm intensities, provide the basis for flood warnings and provide daily, monthly or annual rainfall totals.
