In-Depth Information
- toposcale map (ca. 1:5,000), updated each year, as specified by the WMO
Technical Commission for Instruments and Methods of Observations [WMO 96];
- radiation horizon mapping, updated each year;
- photos taken from all points of the compass and sufficient area of the
enclosure and of instrument positions outside the enclosure, updated upon
significant changes;
- a microscale map of the instrument enclosure, updated when individual
instruments are relocated or when other significant changes occur.

General template for station exposure metadata (from [WMO 96])
A detailed picture of metadata information can be derived from Figure 1.12 for
the example of the climate station at Sonnblick in the Austrian Alps. It is clear from
this figure that many changes occur within short intervals, although this station is
outstanding with respect to station relocations showing no changes over the entire
observation period.
