Site status provides a description of whether an environmental monitoring site within the National Environmental Monitoring Sites Register is active, in-active, decommissioned etc.

Sampling regime is the frequency of site observations. The initial list of sampling regimes is based on a subset of NASA's Global Change Master Directory (GCMD) Temporal Data Resolution keywords (http://gcmd.nasa.gov/learn/keyword_list.html).

Observed property is the  environmental phenomenon (property) being measured at a site, for example, streamflow, soil moisture, or air pressure. The vocabulary of  observed properties is based on a subset of NASA's Global Change Master Directory (GCMD) Science and Services keywords (http://gcmd.nasa.gov/learn/keyword_list.html).

Observation method is a high-level classification of the method used to make environmental observations. The initial list of methods is based on a subset of NASA's Global Change Master Directory (GCMD) Platforms keyword list (http://gcmd.nasa.gov/learn/keyword_list.html).

NEII Licencing describes the type of licence that data are available under.

It details how the data are made available either through data services, online resources or other delivery channels

Drought Rainfall Definitions

Definitions for 9am and 3pm climate statistics terms

Cloud cover observations are measured in oktas (eighths). The sky is visually inspected to produce an estimate of the number of eighths of the dome of the sky covered by cloud. The presence of any trace of cloud in an otherwise blue sky is recorded as 1 okta, and similarly any trace of blue on an otherwise cloudy sky is recorded as 7.
