TEMS, the Terrestrial Ecosystem Monitoring Sites database, is an international directory of sites (named T.Sites) and networks that carry out long-term, terrestrial in-situ monitoring (i.e. in the field) and research activities.
TEMS is being managed by the Global Terrestrial Observing System (GTOS) in FAO, Rome, Italy. Membership is free and encouraged provided some basic requisites are met.
