LTER Data Portal

LTER Data Portal

The LTER Network Information System Data Portal contains ecological data packages contributed by past and present LTER sites.

Environmental Data Initiative (EDI)


The Environmental Data Initiative is an NSF-funded project meant to accelerate curation and archive of environmental data, emphasizing data from projects funded by the NSF DEB. Programs served include Long Term Research in Environmental Biology (LTREB), Organization for Biological Field Stations (OBFS), Macrosystems Biology (MSB), and Long Term Ecological Research (LTER).



Data Observation Network for Earth provides the resources to meet the needs of science and society for open, persistent, robust, and secure access to well-described and easily discovered Earth observational data hrough a distributed framework and sustainable cyberinfrastructure.



The LTER GitHub is a meta-repository that helps with navigation of the repositories under the organizational account "LTER", belonging to the Long Term Ecological Research Network.


GeoNIS is a web service that processes, stores, and displays geospatial data collected by the Long Term Ecological Research Network (LTER), as part of the Network Information System. GeoNIS searches for and downloads spatial data from the Provenance Aware Synthesis Tracking Architecture. Using an ArcGIS Python-based workflow, GeoNIS then processes this spatial data, and makes them available via ArcGIS map and image REST services. An integrated web map, with toggleable vector and raster layers, is included for each LTER site. Detailed GeoNIS reports are also available for each data package, which are accessible from the 'packages' menu.

LTER Network Site Database (SiteDB)

LTER Sites

Site profiles contain key information on research, history, people, institutional affiliations, and location for each LTER site as well as links to additional site information.

Climate and Hydrology Database (ClimDB/HydroDB)


A centralized server to provide open access to long-term meteorological and streamflow records from a collection of research sites.

Eco Trends Project


The Eco Trends Project is a collaborative effort among state and federal agencies and institutions to make long-term ecological data easy to access, analyze, and compare within and across sites.

LTER Network Unit Registry

LTER Unit Registry

The LTER Network Unit Registry is a web service-enabled database of standardized scientific units in use at different levels of the LTER research community.

LTER Controlled Vocabulary

LTER Controlled Vocabulary

The LTER Controlled Vocabulary is a web service-enabled database of standardized controlled vocabularies in use at different levels of the LTER research community.
