Site requirements for solar observations

The WMO maintains a guide to Siting and exposure of meteorological instruments to promote world-wide standardization of observations. The guide may be adapted for local requirements; the current Australian Bureau of Meteorology document is known as "Observation Specification No 2013, Guidelines for the Siting and Exposure of Meteorological Instruments and Observing Facilities."

Basic considerations for selection of an observing site include the following criteria:

Some localities, for which observations are essential, may not have potential sites that fully conform to the siting and exposure guidelines for a variety of reasons. Under these circumstances it will be necessary to balance scientific acceptability against practical and financial considerations.

In addition to the above guidelines, specific requirements for a Bureau solar monitoring site include the following:
