The Environmental Data Initiative Repository concentrates on studies of ecological processes that play out at time scales spanning decades to centuries including those of the NSF Long Term Ecological Research (LTER) program, the NSF Macrosystems Biology Program, the NSF Long Term Research in Environmental Biology (LTREB) program, the Organization of Biological Field Stations, and others. The repository hosts data that provide a context to evaluate the nature and pace of ecological change, to interpret its effects, and to forecast the range of future biological responses to change.
Environmental Data Initiative Repository (formerly: LTER repository) is covered by Thomson Reuters Data Citation Index. Environmental Data Initiative Repository is built on software Provenance Aware Synthesis Tracking Architecture (PASTA). The Network brings together a multi-disciplinary group of more than 2000 scientists and graduate students. The 26 LTER sites encompass diverse ecosystems in the continental United States, Alaska, Antarctica and islands in the Caribbean and the Pacific—including deserts, estuaries, lakes, oceans, coral reefs, prairies, forests, alpine and Arctic tundra, urban areas, and production agriculture.
