Long-term: Local observations (sups_*)
The SAMD archive provides data of different meteorological Observatories. These so called Supersites consist of a multitude of different measurement instruments at one location - local observation. Not only the large number of instruments is specific for the meteorological observatories, but the sustained, long term, often operational measurements with a high quality level. The Supersites yield detailed information about the atmosphere's physical structure from the ground up to the stratosphere.
Supersites and the abbreviation in SAMD are listed in the table.
