Sunshine duration means the time the sun is really seen in the sky and typically casts a shadow. The standard instrument to measure sunshine duration is the Campbell-Stokes sunshine recorder <https://en.wikipedia.org/wiki/Sunshine_recorder>. Sunshine duration is *not* total daylight time. If a cloud is situated before the sun, this is considered no sunshine. If clouds are elsewhere in the sky it does not matter. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
