Final update on water quality chlorophyll measurements assigned incorrect units

September 28, 2023

It was previously reported that chlorophyll-a measurements in the Water quality data product (DP1.20288.001) were being reported in the wrong units

Data Notification

Reduced soil heat flux availability since late 2022 due to processing issue

August 29, 2023

Starting in late 2022 all NEON terrestrial sites were updated with new infrastructure that, among other things, controls the self-calibration process

neonUtilities 2.3.0 is now available on CRAN! Read on to learn more about updates in this version.

Data Notification

Data Impacts for NEON's Sierra Nevada Sites (D17 BIGC, SOAP, TEAK, TECR) due to Excessive Snowpack and Unsettled Spring Weather

June 22, 2023

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.

Data Notification

Update II on water quality chlorophyll measurements assigned incorrect units

June 8, 2023

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.

Data Notification

Update: Uncertainty in pH measurements

June 8, 2023

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.

Data Notification

Logged water quality data available on EDI

April 24, 2023

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.

Data Notification

Data Impacts for NEON’s Yellowstone Sites (YELL, BLDE) due to Catastrophic Flooding - Update

April 10, 2023

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.

Data Notification

Update on water quality chlorophyll measurements assigned incorrect units

March 30, 2023

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.

Data Notification

Water quality chlorophyll measurements assigned incorrect units

March 15, 2023

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.

Data Notification

Update to variable names in sensor positions files

March 13, 2023

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.

Data Notification

New version of neonUtilities (2.2.1)

March 13, 2023

neonUtilities 2.2.1 is now available on CRAN! Read on to learn more about updates in this new version.

Data Notification

Río Guilarte (GUIL) site name corrected to Río Yahuecas

March 2, 2023

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."

Data Notification

Update: Water Quality fDOM Values are Sometimes Artificially Low

October 18, 2022

It was previously reported that fDOM values (Water Quality data product, DP1.20288.001), measured using older model sensor probes, were artificially low. NEON has retired these probes and replaced them with newer models in which the defect has been corrected. It therefore should not occur in any data collected after June 1st, 2022.

Data Notification

'Young Leaves' phenophase missing from published portal data

October 8, 2022

In RELEASE-2022, the phe_statusintensity table in the Plant Phenology data product (DP1.10055.001) did not include observations for the ‘Young leaves’ phenophase for several growth forms for observations made in 2020. These records are also absent in provisional data accessed prior to 2022-10. The processing error that led to omission of these records has been fixed and the data have been reprocessed. 2020 data will be included in RELEASE-2023.
