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.
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.
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.

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.
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 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.
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.

The winter of 2022-23 brought above average precipitation to all of California, starting in early November (Figure 1). In Sierra Nevada, much of this precipitation fell during atmospheric river events that dropped four to six inches of water (two to six feet of snow) in no more than a few days, with most precipitation falling as snow above 6000 ft. The storms caused extensive damage to roads and buildings, road closures due to excessive snow accumulation or washouts, and low and mid-elevation flooding.
It was previously reported that grab sample pH measurements in Chemical properties of surface water (DP1.20093.001) did not always align with contemporaneous in-situ sensor pH measurements in Water quality (DP1.20288.001). In response, NEON has taken several corrective actions.
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). We are continuing to work on correcting and republishing the affected data.
When infrastructure damage, loss of power/communications, or other issues prevent data from streaming, NEON is able to put some sensors into logging mode, running off battery power and saving data internally. This data is planned to ultimately be ingested into our data processing pipeline and published. Some data are available in an Environmental Data Initiative repository.
This is an update to the earlier data notification, "Data Impacts for NEON’s Yellowstone Sites (YELL, BLDE) due to Catastrophic Flooding" in August 2022, which notified users of the gaps in data collection resulting from both power loss and extreme road damage that resulted from the flooding. As of October 31, 2022, the National Park Service opened a newly constructed road from Gardiner, MT to Mammoth, WY with minimal restrictions. Consequently, beginning on that date, normal operations in Domain 12 at YELL and BLDE were able to resume.
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 for the ten river and lake sites. The underlying cause has been fixed, and all data collected after 16 March 2023 are reported in the correct units.
Chlorophyll-a measurements in the Water quality data product (DP1.20288.001) are being reported in the wrong units starting in late 2021 or early 2022 for the ten river and lake sites. Read on for more information on the issue and actions being taken.
Sensor positions files published with instrument data provide spatial information about the physical locations of sensors. The variable names in these files have been updated to more accurately describe the contents of each column, and descriptions of each variable have been added to the variables files.
The NEON stream site in Domain 04 which was being called Río Guilarte is actually located in the Río Yahuecas. This happened because both streams are located within the same USGS 12-digit Hydrologic Unit (210100030201, Río Guilarte at Lago Yahuecas Dam). Moving forward, the site name in NEON documentation will be updated to Río Yahuecas, while the 4-digit NEON siteID used to retrieve the data from the NEON data portal and the API will remain "GUIL."
