. The observatory is among the first to detect and enable forecasting of ecological change at continental scales over multiple decades. NEON has partitioned the United States into 20 ecoclimatic domains, each of which represents different regions of vegetation, landforms, climate, and ecosystem performance. Data is collected by field technicians and passive sensors at strategically selected sites within each domain and synthesized into information products that can be used to describe changes in the nation's ecosystem through space and time. NEON data products are freely available via a web portal.


Purpose and function


Science

The data NEON collects are defined by a series of Grand Challenges, as identified by the National Research Council at the request of the National Science Foundation. The National Research Council established a committee to evaluate the major ecological, environmental, and national concerns that require a continental-scale observatory, and it identified the following Environmental Grand Challenges: *
Biogeochemistry Biogeochemistry is the Branches of science, scientific discipline that involves the study of the chemistry, chemical, physics, physical, geology, geological, and biology, biological processes and reactions that govern the composition of the natu ...
: The study of how chemical, physical, geological, and biological processes combine to create the natural environment. *
Biodiversity Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distribut ...
: The full range of life forms on earth, or in a particular region. *
Climate change Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in ...
: A significant long-term change in the kind of weather we would expect based on averages calculated from climate data. *

Infectious Diseases infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease, also known as a transmissible disease or communicable dise ...
: Diseases spread by viruses, parasites, and bacteria that are sometimes transmitted to people by animals, birds, and insects. *
Land Use Land use is an umbrella term to describe what happens on a parcel of land. It concerns the benefits derived from using the land, and also the land management actions that humans carry out there. The following categories are used for land use: fo ...
: The many ways that people change the natural landscape and environment, such as by building cities, cutting down forests, or planting crops. *
Invasive Species An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native spec ...
: Plants and organisms that overpopulate a particular place, or species that move into areas they have not lived in before. Thus, the data and observations that NEON collects focuses on how land use, climate change and invasive species affect biodiversity, disease ecology, and
ecosystem services Ecosystem services are the various benefits that humans derive from Ecosystem, ecosystems. The interconnected Biotic_material, living and Abiotic, non-living components of the natural environment offer benefits such as pollination of crops, clean ...
. Obtaining integrated data on these relationships over a long-term period is crucial to improving forecast models and resource management for environmental change. The National Science Foundation's vision for NEON is described as:
"A continental scale research instrument consisting of geographically distributed infrastructure, networked via state-of-the-art communications. Cutting-edge lab and field instrumentation, site-based experimental infrastructure, natural history archive facilities and/or computational, analytical and modeling capabilities, linked via a computational network will comprise NEON. NEON will transform ecological research by enabling studies on major environmental challenges at regional to continental scales. Scientists and engineers will use NEON to conduct real-time ecological studies spanning all levels of biological organization and temporal and geographical scales. NSF disciplinary and multi-disciplinary programs will support NEON research projects and educational activities. Data from standard measurements made using NEON will be publicly available.” (NSF 04549, 2004)NSF Synopsis for NEON

And, what is the pace and pattern of the responses? * How do the internal responses and feedbacks of biogeochemistry, biodiversity, hydroecology, and biotic structure and function interact with changes in climate, land use, and invasive species? And, how do these feedbacks vary with ecological context and spatial and temporal scales?


Education

The data and information products that NEON collects and provides is readily available to scientists, educators, students, decision makers and the public to use to understand and address ecological questions and issues. Data is provided as meaningful information and learning tools that engage many audiences, including members of underserved communities, and promote broad ecological literacy.


History

NEON was initially conceived in 2000, with a preliminary plan being developed in 2006. The National Science Foundation, the National Science Board and Congress approved funding for NEON in 2011. The program was fully operational in 2019. Beginning in 2011, NEON, Inc., the entity in charge of initially running the NEON project, was audited by the
Defense Contract Audit Agency The Defense Contract Audit Agency (DCAA) is an agency of the United States Department of Defense under the direction of the Under Secretary of Defense (Comptroller). It was established in 1965 to perform all contract audits for the Department o ...
on behalf of the National Science Foundation Office of the Inspector General. Auditor-in-Charge J. Kirk McGill determined that NEON, Inc. had poor control over taxpayer funds and could easily go over budget with little or no warning. He also found that NEON, Inc. had spent taxpayer funds on illegal expenditures including alcohol, lobbying, parties, and luxury travel. When McGill's findings were not addressed, he disclosed the matter directly to Congress. Hearings were held in 2014 and 2015. The House Committee on Science, Space, and Technology ultimately substantiated McGill's allegations, and NEON, Inc., was dismissed from the project. This represents one of the largest Federal agreement terminations for cause in history. The NSF chose Battelle to complete the construction of the observatory.


Layout

NEON has categorized five types of measurement systems: the Airborne Observation Platform, Aquatic Instrument System, Aquatic Observation System, Terrestrial Instrument System, and Terrestrial Observation System.


Airborne observations

NEON takes airborne photography and performs aerial

observations of the sites being studied. This is accomplished by slow flying aircraft surveying at 1,000 meters above the ground.


Aquatic sites

Aquatic site sampling depends on the type of environment, varying between streams, rivers, and lakes. Automated sensors assess water quality and depth and manual observations study organisms, biogeochemistry, hydrology, and morphology.


Terrestrial sites

Each terrestrial site studied by NEON includes 30 randomly distributed plots. At select plots, technicians monitor soil biogeochemistry and microbes; plant diversity, biogeochemistry, biomass, productivity, and leaf area index; beetle diversity; mosquito prevalence, diversity, phenology, and infectious disease; small mammal diversity, demography, and disease; avian diversity; and tick‐borne diseases. Each terrestrial site is outfitted with soil sensor arrays and a tower mounted with sensory equipment. Towers are built to extend above the vegetation canopy and take measurements such as on air quality, carbon dioxide flux, temperature, and atmospheric pressure. Additional sampling plots are located within the airshed of the tower.
