Data for the Litterfall and fine woody debris production and chemistry data product (DP1.10033.001) were published without data on total cover of qualifying vegetation (woody individual > 2M height). RELEASE-2024 and releases and provisional data thereafter include a new table 'ltr_vegetationCover' that provides cover of qualifying woody vegetation at the scale of the subplot for all deployed traps at all sites.
A recent paper in Environmental Research: Ecology explores the potential for using air- and spaceborne lidar to monitor biodiversity on a global scale. The study used NEON airborne laser scanning (ALS) data with NASA's Global Ecosystem Dynamics Investigation (GEDI) spaceborne lidar to validate a unique approach that uses "characteristic" forest structure to infer biodiversity for areas difficult to directly sample.
Certain AOP data products will be temporarily unavailable or in transition prior to RELEASE-2024. We recommend holding off on downloading AOP data during this transition period, or using the Contact Us form to request the status of any specific AOP data product(s), site(s), and year(s). This process is estimated to be complete by the end of January 2024.
We have discovered an 8-minute timestamp offset in data from all Picarro instruments, beginning 19 September 2023 and ending 30 November 2023. This issue only affects data collected by the instrument, not the valves that control switching measurement levels, which leads to incorrect partitioning of data to each measurement level and validation gas in data processing.
The availability of large, open data sets is changing the way ecologists conduct research and the way ecology is taught. Open data from the NEON program and other large ecology networks are a potential goldmine for undergraduate and graduate educators.
NEON recently discovered two issues with the way an external laboratory was storing samples and reporting quality assurance data for foliar chlorophyll. All impacted records have been flagged in the cfc_chlorophyll table in DP1.10026.001 Plant Foliar Traits.
It was discovered that some sensorDepth values recently published in the Water Quality (DP1.20288.001) data product are incorrect for some lake sites. We suggest users download the expanded data package with the more detailed quality flags to better identify affected data, and then substitute an approximate depth of 0.5 m.
Fall arrives at different times and in different ways across the Observatory. Here's a glimpse at how autumn is unrolling across NEON field sites, viewed through phenocams at our field sites, and how 2023 looks compared to 2022.
The NEON Great Lakes User Group brings people together in the Great Lakes region to foster collaborative research opportunities. In September, the first in-person meeting of GLUG was held, a workshop supported through an NSF award.
At the 32 sites where breeding landbird point counts are conducted in 9-point grids, two-thirds of counts have been reported with incorrect point IDs due to a transposition error when convertingnumeric point labels (1-9) into alphanumeric point IDs (A1-C3) during data ingest.
NEON has weathered several unexpected events. Through it all, the Observatory team, managed by Battelle, has responded with ingenuity, resilience, and a positive spirit to ensure the safety of our people and maximize data continuity and availability.
An error in many of the sensor calibration files means that the reported measurement uncertainty in the soil water content data product (DP1.00094.001) is lower than the actual measurement uncertainty for many locations.
The conductivity timeseries data in Reaeration and Salt-based discharge are being moved into individual files per sampling event. This affects the rea_conductivityFieldData and sbd_conductivityFieldData tables. Users of these data should update neonUtilities to version 2.4.0 or greater to ensure correct data stacking.
The Data Portal and the neonUtilities R package have been updated to default to downloading only data from the most recent Data Release. Provisional data, which are subject to change without notice, are still accessible, but are downloadable on an opt-in basis, rather than opt-out.
A recent paper in Global Ecology and Biology, Habitat–trait interactions that control response to climate change: North American ground beetles, explores the connections between climate change, habitat types, and ground beetle traits. The study could help researchers model which ground beetle species may be at risk and the habitats needing protection to preserve them.
The Data Portal and the neonUtilities R package are being updated to default to downloading only data from the most recent Data Release. Provisional data, which are subject to change without notice, will still be accessible, but will be downloaded on an opt-in basis, rather than opt-out.
Through collaboration with Ameriflux Management Project (AMP), data from 27 NEON sites have been processed using ONEFlux software to generate the AmeriFlux FLUXNET data product.
The NEON naming convention for subplots within Base plots, at which several Terrestrial Observation (TOS) protocols are implemented, is being changed to clarify the location of data collection.
In July, the NEON Ambassadors convened a virtual workshop focusing on NEON derived data products. Participants are now working on a summary paper to outline best practices in creating, validating, and using derived data products. It's one more way the NEON Ambassadors are helping to make NEON data more usable and understandable for the wider research community.
The soil heat flux data processing code has been updated to account for the change in timing introduced by the new site infrastructure. All affected data have been reprocessed and republished and soil heat flux data availability has returned to previous levels.
It was previously reported that chlorophyll-a measurements in the Water quality data product (DP1.20288.001) were being reported in the wrong units starting in late 2021 or early 2022 and ending March 16, 2023 for the ten river and lake sites (BARC, BLWA, CRAM, FLNT, LIRO, PRLA, PRPO, SUGG, TOMB, and TOOK). The issue has been corrected, and all provisional data not included in RELEASE-2023 (collected since July 1, 2022) were updated on the Data Portal.
We spoke with Dr. Phoebe Lehmann Zarnetske, an ecologist and associate professor at Michigan State University, about her path through academia, the importance of interdisciplinary collaboration, and the challenges of maintaining a work-life balance. She also shares her thoughts on what it will take for scientific contributions to be more widely adopted for broader societal challenges.
Can water quality be forecast just like the weather? For Dr. Quinn Thomas, that is the ultimate goal. He and fellow researchers tested a model for forecasting lake temperatures at six NEON lake sites. Their results were recently published in Frontiers in Ecology and the Environment. Thomas is also the Principal Investigator for the EFI-RCN NEON Forecasting Challenge, which seeks to create a community of ecological forecasters using NEON data to test forecasting models.
2023 marks the 10th anniversary of operations for NEON's Airborne Observation Platform (AOP)! The effort that goes into making the flight schedules, calibrating the instrument payloads, making sure everything goes smoothly, and collecting high-quality data requires a dedicated team. The AOP team consists of many moving parts and a myriad of brilliant staff. Meet some more of the team here!
Starting in late 2022 all NEON terrestrial sites were updated with new infrastructure that, among other things, controls the self-calibration process for the soil heat flux sensors (DP1.00040.001). A number of factors have lead to a decline in the amount of valid soil heat flux data. The data processing code is being updated to correct this issue, and it is anticipated that the adjustments will allow soil heat flux availability to return to previous levels.
A unique and endangered ecosystem is nestled in the midst of the city of Oak Ridge, Tennessee. The Oak Ridge Barrens (The Barrens) is home to some of the few remaining pockets of natural prairie left in the state. Tennessee Citizens for Wilderness Planning (TCWP) wanted to perform a scientific inventory of the species composition in the cedar barrens. Margaret Cumberland, ecologist at NEON's Appalachians and Cumberland Plateau Domain (D07), facilitated an AGU-TEX community project to make this happen.
