Data Notifications

An interim solution is starting to be implemented at all terrestrial sites that is expected to increase soil water content (DP1.00094.001) data availability, but may result in a step change in the soil moisture time series until all data are reprocessed through a new data processing system.

Planning to publish your work based on NEON data, samples, or resources through the Assignable Assets program? We just published a new webpage with helpful tips and guidelines!

Macroinvertebrate collection (DP1.20120.001) field data in the table inv_fieldData for all aquatic sites from 2014 through 2019 are duplicated on the NEON data portal due to an error on data transition for this table. Corrections have been made, but will not appear on the portal until the 2022 data release.

neonUtilities 2.0.1 is now available on CRAN! This new version resolves several bugs in the initial release of neonUtilities 2.0.0; update is highly recommended.

AIS field maintenance and calibration data are now available for the following data products for provisional data (primarily data collected July 1st, 2020 and after). Read on to see which data products provide these tables.

This is an update to the previous post concerning wind direction data on the buoys. NEON has field-verified wind monitor orientation discrepancies at most buoy sites, which adversely affect wind direction data in Wind speed and direction on lakes on-buoy (DP1.20059.001). Buoy wind direction data will be corrected with measured offsets and/or quality flagged following further review over the next 6 months.

Issues identified with fDOM temperature and absorbance data have been resolved. The correct fDOM data are available on the portal and were included in NEON's first data release.

There are a few known code bugs in neonUtilities 2.0.0. A patch update resolving these bugs will be delivered in February, and workarounds for avoiding them are described here.

neonUtilities 2.0.0 is now available on CRAN! This new version contains critical updates for working with the NEON Data Release and associated API and Portal changes. An update to 2.0.0 is required for working with any newly downloaded data.

Based on an analysis of nutrient data, NEON has determined that the method detection limits (MDLs) required of the external laboratory for surface water and groundwater nutrient analyses are too high for many sites. New analyses of frozen samples will take place in the future.

Surface water microbe cell count (DP1.20138.001) laboratory data for all aquatic sites from 9/2017 to 9/2020 were found to have incorrect calculations populating rawMicrobialAbundance data field. Data have been removed from the data portal while revisions are made and will be republished by February.

Due to a miscommunication, samples analyzed for carbon (C) and nitrogen (N) concentrations and stable isotopes were not previously re-dried prior to weighing and analysis at the external laboratory. Affected data have been flagged and a new protocol was implemented.

To reduce uncertaintly in surface and groundwater elevation data, permanent benchmarks have been installed at most aquatic sites to serve as controlled location reference points. Updated elevations from the associated site resurveys are available on the data portal. Surface and groundwater elevation data products have been reprocessed, and, the corrected data will be available via the data portal by January 18, 2020.

neonUtilities 1.3.9 is now available on CRAN. This update includes minor bug fixes.

The sunlit plant foliage major, minor, and trace element data (DP1.10026.001, cfc_elements table) collected in 2017 and 2018 were investigated and deemed untrustworthy. Sample major, minor, and trace elements were re-measured using foliar material from the NEON Biorepository. Following review, these new data were posted to the Data Portal on 2020-10-29.

At all sites with profiling water quality sondes on buoys, the Water quality data product (DP1.20288.001) reports the depth of the multisonde as it profiles through the water column. Data users should be aware that sensor depth is approximate, as the multisonde’s pressure transducer is not vented to the atmosphere. Therefore, barometric pressure fluctuations following calibration will cause a sensor depth discrepancy.
