From floods and wildfires to land use and invasive species,

The National Ecological Observatory Network, or NEON, is designed to collect data

at field sites across the United States to help us better understand these ecosystems,

The NEON project will transform scientists' ability to study our nation's ecosystems by

providing a wealth of open data and a continental-scale infrastructure for research studies.

First, NEON uses a combination of data collection methods

that are spatially integrated within and across field sites.

Second, the data collection methods used are standardized across all sites

to enable comparisons across the continent.

Integrate ecological observations across multiple scales.

Detect changes in how our ecosystems function.

Enable forecasting of environmental change to inform resource management decisions.

NEON field sites are strategically located in both terrestrial and

freshwater aquatic ecosystems across the United States.

They represent the vegetation, landforms and climates of those regions.

At each field site, NEON uses a combination of automated instruments,

observational sampling, and airborne remote sensing technologies

to collect data that characterize plants, animals,

soils, nutrients, freshwater and atmosphere.

NEON's automated instruments collect data 24/7

at terrestrial and aquatic field sites across the nation.

Flux towers, that rise above the plant canopy at terrestrial sites,

collect a full profile of atmospheric measurements,

along with sensors installed in the ground that monitor soil health.

At aquatic sites, a smaller meteorological station collects atmospheric data and

other sensors monitor surface water and groundwater quality.

In addition to instrument systems, NEON has trained field technicians

that conduct standardized sampling throughout the growing season

at dozens of plot locations within each field site.

They collect organismal and biogeochemical observations that range from plants and animals

Morphology maps of the aquatic field sites are collected

as well as hydrology data to monitor physical changes that occur over time.

During peak greenness, NEON's airborne observation platform

hyperspectral, lidar, and high resolution camera data.

These remote sensing systems capture changes to land characteristics like

topography as well as more complex processes

like tree growth and forest health across an entire site from year to year.

The data collected through these three systems

can be studied in conjunction with one another because they're

gathered in close proximity to each other at a site.

The data are also comparable among field sites

so researchers can study connections and patterns across ecosystems,

and then develop models to forecast environmental change locally,

NEON is an open science program which means all NEON data, protocols and resources are

are freely available online for anyone to use!
