Table S2A. NTL-LTER Data Available
Electronically.
i. Datasets available online
in the data catalog of the NTL website; ii. Other data
available in electronic format.
NTL has established the following definitions for categorizing the
datasets that are managed in the information system:
Core parameter / Core data
Core data are collected,
processed, and archived by NTL-LTER PIs, students, and/or staff using
established protocols. In some cases, a
core dataset may be derived from data acquired from an outside source (e.g.,
The U.S. Census Bureau). The designation of "core parameter" implies
that the NTL-LTER program is committed to ongoing collection. Core parameters are essential to the
perception of long-term change in the NTL-LTER study areas.
Associated data
Associated data are collected
and archived by NTL-LTER PIs, students, and/or staff for a limited duration. In some cases, an associated dataset may be
derived from data acquired from an outside source. Associated data sets are project-based and there
is no formal commitment to collect the data beyond the life of the short-term project.
Reference data
Reference data are not
collected by NTL-LTER, but are archived by NTL-LTER. Reference data are typically derived from
datasets collected for other purposes. Reference data assist with placing core
and associated data in an appropriate context.
There may or may not be a formal commitment to update, derive, and
archive reference data sets over time.
