Externally Hosted Data

Numerous NEON data products are hosted at external repositories that best support specialized data, such as surface-atmosphere fluxes of carbon, water, and energy, and DNA sequences. For each data product that we host elsewhere, we provide links from the data product detail page to the corresponding webpage(s) at the external repository. 

AERONET

Data streams from the spectral sun photometer are sent directly to NASA for processing. The Aerosol Robotic Network, or AERONET, is run by NASA’s Goddard Space Flight Center and is a central repository for sites around the world that use the same sensor. Data are generally available within a few days of collection. 

To locate data, either view the Spectral Sun Photometer - Calibrated Sky Radiances data product details webpage, or visit AERONET’s global list of sites and look for site names beginning with “NEON_”. The NEON data portal does not provide direct downloads of this data product. AERONET also does a broad range of data processing and visualization, so this is a great resource for other data, including aerosol optical depth and water vapor.

AmeriFlux

NEON terrestrial sites are also registered with AmeriFlux, a community network for sharing data related to surface-atmosphere fluxes of carbon, water, and energy. A number of relevant NEON data products, available on NEON’s data portal, are also sent to AmeriFlux for co-hosting and are made available in the same format as other AmeriFlux site data. AmeriFlux will be producing NEON’s gap-filled meteorological data products as well as several additional derived data products. These are made available following AmeriFlux’s product release schedule. NEON data are sent to AmeriFlux at least once per year, and are made available directly from AmeriFlux following AmeriFlux’s processing timeline. 

CDC Tick Surveillance

The Centers for Disease Control and Prevention (CDC) manage tick and tick-borne pathogen surveillance data from a variety of sources, including state health departments. Released NEON tick and tick pathogen data are re-formatted and submitted to the CDC for upload to the tick surveillance system once per year. These data are used to generate maps of vectors and pathogens and are also made available to researchers. All data are collated at the county level and thus it is not possible to retrieve individual NEON data records from the raw data files.

Barcode of Life Databases (BOLD)

DNA barcoding is a method to help identify or confirm identifications of sampled species, particularly ones that are difficult to identify by morphology. Barcoding is used at NEON 1) for cases where an expert taxonomist or field taxonomist is not able to classify a cryptic or poorly described species or 2) to perform QA/QC on identifications. After the CO1 gene for each sample is sequenced by an external analytical facility, the sequence data and metadata are sent to the Barcode of Life Databases (BOLD). There is one project on BOLD for each of NEON’s four barcoding data products:

• Ground beetle sequences DNA barcode
• Mosquito sequences DNA barcode       
• Fish sequences DNA barcode
• Small mammal sequences DNA barcode

For each of these products, sampling data are provided through the NEON data portal, and links are provided to the corresponding project at BOLD.

Since the barcoding data are generated at the end of a long processing chain, including waiting for all of the sampling and expert taxonomist identifications to be completed prior to sample selection for DNA barcoding, the latency can be a year or more. 

GBIF

The Global Biodiversity Information Facilities (GBIF) "is an international network and research infrastructure funded by the world's governments and aimed at providing anyone, anywhere, open access to data about all types of life on Earth". NEON's Biorepository packages all records associated with NEON samples and uploads them to GBIF, making these records part of a rich global database. 

Google Earth Engine

NEON has added a subset of the Airborne Observation Platform (AOP) (NEON Airborne Remote Sensing) data products to Google Earth Engine (GEE), an optimized cloud-computing platform for conducting remote sensing data analysis. GEE is free for research purposes (non-commercial use). Data on GEE will provide another avenue through which researchers can access and work with AOP data; all AOP data products can still be accessed as usual through the NEON Data Portal.

The AOP datasets are now searchable and findable on the GEE Publisher Data Catalogs. All AOP datasets can be seen here, or if you search for "NEON" in the Earth Engine Data Catalog or through the code editor search bar.

Phenocam Gallery

NEON has deployed a Stardot NetCam on the top and bottom of all terrestrial towers to study above- and below-canopy phenology. Every 15 minutes each camera captures back-to-back Red, Green, Blue (RGB) and Infrared (IR) images. Over time, these images can be used to detect seasonal changes in vegetative canopies (e.g., onset of leaf growth and senescence). At all aquatic sites, a phenocam is deployed to capture the land-water interface. Photos may also be used for qualitative estimates of snow cover, riparian characteristics, or weather.

Images are sent to and processed by PhenoCam, a cooperative network that archives and distributes imagery and derived data products from digital cameras deployed at research sites across North America and around the world. NEON’s phenocam images are generally available within one day for viewing and downloading from the PhenoCam Gallery, along with images and data from other phenocam sites across the world.
