A CONTINENTAL-SCALE OBSERVATION SYSTEM

A Continental Observation System

30 year period of observation

… to enable understanding and forecasting of the impacts of climate change, land use change and invasive species on

continental-scale ecology

…by providing infrastructure to support research, education and environmental management in these areas

The NEON Questions

Where will NEON observe?

Observing Ecological Change

• Representative sampling

• Replication of gradients

• Detecting/attributing change over decades

• Standardized and transparent protocols

• Comprehensive set of observations

• Terrestrial and aquatic

• Sentinel taxa

• Field and lab analyses state-of-the-art

• QA/QC -- data quality and uncertainty

Free and open access to all NEON data*

* Unless legislatively protected

NEON Data Products

• ~ 1600 Level 0 data products (primary observations)o Raw voltages from sensorso Information on collected flora/fauna(e.g. counts)o External DNA or chemical analysiso Raw LiDAR returns

• ~ 540 Level 1 data (QA/C, minimally processed)o One-minute average air temperatureo Site-level species compositiono Georectified LiDAR

• ~ 75 Level 2 (rectified) & Level 3 (common gridded)o Gap-filled one-minute air temp (L2)o Gridded canopy nitrogen estimate (L3)

• ~ 120 Level 4 (high-level, cross-subsystem integrative)o Net ecosystem exchangeo Canopy nitrogeno Microbial diversityo Aquatic nutrient flux

• Terrestrial • Organismal (TOS)

• Instrumental (TIS)

• Aquatic• Organismal (AOS)

• Instrumental (AIS)

• Airborne (AOP)

• Research: Stream Ecological Observation Network (STREON)

Airborne Observation Platform

2014: Toolik, Barrow, Caribou-Poker, & Healy

The NEON Imaging Spectrometer

Continuous wvl coverage from 380 to 2510 nm High signal-to-noise ratio

(2x improvement over AVIRIS) 5 nm spectral sampling 1 mrad IFOV (1m GSD @ 1000 m flight altitude) High degree of uniformity across wvl‘s and field SWIR coverage provides information on

canopy moisture & nitrogen discrimination of non-photosynthetic components
