Methods for measuring sunshine have changed over time, older records and some climate sites today will use a Campbell-Stokes sunshine recorder, whereas nowadays the majority of measurements will be taken using a pyrheliometer and threshold of 120 W/m^2 for sunshine. The instrumentation used is indicated by the letters in the table - WMO means a pyrheliometer was used, CS means a Campbell-Stokes recorder was used, and S means that the value was extracted from the SYNOP report (most likely to be a pyrheliometer measurement but not for certain). Clicking on an icon in the map will display a popup which also contains this information.

It is possible to convert the newer pyrheliometer measurements to a Campbell-Stokes equivalent for a fairer comparison across time, which is done for climatological purposes, and is a function which I may add to this page at some point.
