February 4, 2021

AOP has updated the file name, format and metadata for the Spectrometer Ortho-rectified at-sensor radiance data product (DP1.30008.001). The compression of the data has improved, and updates to end users' code may be needed.

Data Notification

Orientation Discrepancies in Lake Buoy Wind Direction Data: Update 1

February 4, 2021

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.

Data Notification

Resolved: fDOM temperature and absorbance correction algorithm updates

January 29, 2021

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.

Data Notification

Known Issues in neonUtilities 2.0.0

January 27, 2021

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.

Data Notification

New version of neonUtilities (2.0.0)

January 26, 2021

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.

Data Notification

Delay in analysis of external lab surface water and groundwater nutrient data

January 25, 2021

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.

Data Notification

Surface water microbe cell count (DP1.20138.001) lab data corrections pending

January 20, 2021

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.

Data Notification

Plant and soil samples not re-dried prior to carbon/nitrogen analyses, impacts to data quality

January 19, 2021

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.

Data Notification

Resolved: Surface water and groundwater elevation data improvements

January 14, 2021

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.

Data Notification

New version of neonUtilities (1.3.9)

January 12, 2021

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

Data Notification

Upcoming Error Corrections for Tick Data

December 21, 2020

We have discovered an error in the larval tick count data collected in 2016-2017 in Ticks sampled using drag cloths (DP1.10093.001) that affects all sites. Samples from the tick taxonomy laboratory had a count of 1 larva in the taxonomy table no matter how many individuals were present in the sample. The data will be rectified within 2-3 weeks.

Data Notification

Update 6: Microbial Community Composition Data Products Being Reprocessed

December 15, 2020

The NEON microbial community composition data products have been re-processed and will be available on the NEON data portal either as provisional data (2014-12 and earlier data, 2018-10 and later data) or in the initial NEON data release (2015 through 10-2018 data) in January 2021.

Data Notification

Resolved: Temporary removal of foliar trace element data

December 15, 2020

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.

Data Notification

Fluctuations in Buoy Sonde Depth Data

November 23, 2020

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.

Data Notification

fDOM temperature and absorbance correction algorithm updates

November 23, 2020

Errors were discovered in NEON.DOC.004931 (version A), the Algorithm Theoretical Basis Document (ATBD) for the Water quality (DP1.20288.001) data product. These errors impact the temperature and absorbance corrections applied to fluorescent dissolved organic matter (fDOM) data.

Data Notification

Orientation Discrepancies in Lake Buoy Wind Direction Data

November 23, 2020

All sites with buoys (SUGG, BARC, FLNT, CRAM, LIRO, TOMB, BLWA, PRPO, PRLA, TOOK), need to be verified for appropriate wind direction data from the Wind speed and direction on lakes on-buoy data product (DP1.20059.001).

Data Notification

2D wind direction data products omit North direction

November 23, 2020

All NEON wind direction data at all sites under-report average wind direction frequency in the ~360 to ~5 degree range. This includes wind direction data in both 2D Wind speed and Direction data products: DP1.00001.001 and DP1.20059.001.
