Welcome to Worldwide Sunrecorder
These are the worldwide sites using the Blake-Larsen Sunrecorder.
The Blake-Larsen Sun Recorder is a fully automatic system
designed to measure the duration of sunshine from dawn to dusk.
The graphs show the total bright sunshine recorded for each of the past 12 months,
or since the B-L Sunrecorder was installed, for the period between sunrise and sunset
and comparing to the local climate normals (where historical information is available).
Red bar = sunshine | Grey bar = no sunshine | Blue bar = no recording | Green bar = historical
