Richard, you say that the UVNZ app graphically displays UVI for each situation as functions of time and location maps. Am I right in assuming that UVI at my particular time and location will be calculated by deriving a particular reading from relevant UVI instruments which NIWA operates and transmits real-time readings and then modifies real-time UV intensity at my location by calculating the effect of cloud cover at my location using weather maps produced by satellites every 15 minutes?
