Changes between RELEASE-2023 and RELEASE-2024

  • For all OS data products, data quality improvement and error correction are continuous and ongoing processes. Routine data entry errors (such as transcription errors, duplicate records, or adjusted spatial coordinates) have been corrected where possible. Due to the large volume of data (>20 million data records), these corrections are not described individually. The table below describes significant changes to data products between releases.
  • Isolated sites and time periods for most IS products were reprocessed to incorporate corrections to sensor installation periods, geolocation data, and manual quality flags.
  • For all AOP data products, data quality improvement is an ongoing process. The bulk of the changes in the 2024 Release involved updating the Ecosystem Structure (DP3.30015.001) product, using an improved implementation of the pit-free Canopy Height Model algorithm. In addition, L3 lidar data products for two site-years were corrected to remove erroneous noise and properly classify mis-classified noise in the discrete lidar point cloud data. This mis-classified noise resulted in artifacts in the derived lidar data products, as well as orthorectification errors in the spectrometer and camera data products. A number of sites were excluded from RELEASE-2024 to provide time to correct for this mis-classified lidar noise issue identified in other sites. Finally, minor corrections were made to various AOP data products, sites, and years including fixing spatial referencing, re-naming files, removing duplicated files, and adding missing QA reports in order to improve consistency and follow AOP's standard naming and data organization conventions. Due to the large volume of data, the more minor corrections are not described individually, but the table entries below summarize significant changes to data products between releases. For more information on the AOP 2024 Release Updates, please refer to AOP Data Availability Notification – Release 2024.
Data Product ID Data Product Name Summary of changes between RELEASE-2023 and RELEASE-2024
DP1.00002.001 Single aspirated air temperature Data were reprocessed with an adjustment to the quality control algorithm that checks for sufficient air flow through the aspirated shield (flow test). The adjusted algorithm continues to raise the final quality flag when the data fail the flow test, but impacted data are no longer removed prior to averaging. 
DP1.00003.001 Triple aspirated air temperature Data were reprocessed with an adjustment to the quality control algorithm that checks for sufficient air flow through the aspirated shield (flow test). The adjusted algorithm continues to raise the final quality flag when the data fail the flow test, but impacted data are no longer removed prior to averaging. 
DP1.00006.001 Primary precipitation Data were reprocessed with an interim algorithm to better show spurious trace precipitation, reduce bias in long-term sums, and improve quality flagging. 
DP1.00013.001 Wet deposition chemical analysis Uncertainty fields were removed from lab data as they were inaccurately documenting the method detection limit. A "sampling impractical" workflow was established in July 2023.
DP1.00014.001 Shortwave radiation (direct and diffuse pyranometer) The minimum range threshold for direct radiation was reduced from 0 W/m^2  to -5 W/m^2 to accommodate uncertainty in the measurement. Data were reprocessed.
DP1.00066.001 Photosynthetically active radiation (quantum line) Data were reprocessed using NEON’s new instrument processing pipeline. Computation of skewness and kurtosis statistics were updated to reflect the formulation presented in the product's Algorithm Theoretical Basis Document. 
DP1.00095.001 Soil CO2 concentration Data from NEON site PUUM are now available and included in RELEASE-2024.
DP1.10026.001 Plant foliar traits For 2021 chlorophyll samples, all records were flagged to communicate improper analytical lab storage at -20C instead of ultracold temps. In addition, the relativeAccuracyScale field set to 'not available' because the lab was not using an appropriate check standard. For 2020 and 2021 elements data, the 'soil contamination' part of the flags associated with Fe or Mn values were removed. In the long-term summary table for carbon and nitrogen analyses, uncertainty values contain updated metrics that better conform with NEON definitions of uncertainty terms.  
DP1.10033.001 Litterfall and fine woody debris production and chemistry Added new table, ltr_vegetationCover, to enable subplot, plot, and site level scaling of litter production. In the long-term summary table for carbon and nitrogen analyses, uncertainty values contain updated metrics that better conform with NEON definitions of uncertainty terms.  
DP1.10043.001 Mosquitoes sampled from CO2 traps The dryIceStatus column from the mos_trapping table has been changed to CO2Status to reflect the use of CO2 cylinders to bait mosquito traps at numerous sites.  A value of "present" means that the CO2 bait was still available at the time of trap collection, and "absent" means it ran out.  "Flow obstructed" indicates that the dry ice vent hole was plugged or the tubing for the CO2 release was clogged.
DP1.10047.001 Soil physical and chemical properties, distributed initial characterization In the lab summary table, a column formerly called 'analyteAccuracy' was renamed to 'analyteAbsoluteError' to better conform with NEON definitions of uncertainty terms.
DP1.10055.001 Plant phenology observations Added new table, phe_identificationHistory, to track changes to taxonID in the phe_perindividual table.
DP1.10058.001 Plant presence and percent cover The subplot naming convention for Base plots was updated across all data products with observations and samples that originate in Base plots. The new format consists of the identity of the plot point in the southwest corner of the subplot, the scale or size of the subplot, and, for those subplots smaller than 100 m2, the corner of the 100 m2 subplot in which the smaller subplot is located. For more details, see the associated Data Notification: NEON Terrestrial Observation System (TOS) Base plot subplot renaming.
DP1.10067.001 Root biomass and chemistry, periodic In the long-term summary table for carbon and nitrogen analyses, uncertainty values contain updated metrics that better conform with NEON definitions of uncertainty terms. In addition, values for ‘samplingImpractical’ are now recorded at the level of the core rather than the plot. The ‘rootSamplingPossible’ field has also been removed, and records that formerly had a ‘rootSamplingPossible’ value of “N” now have a ‘samplingImpractical’ value of “obstruction” to more clearly and simply indicate that sampling was attempted but was not possible. In addition, if ‘samplingImpractical’ is not either “OK” or “obstruction”, edits were made to remove ‘clipCellNumber’, ‘clipID’, ‘sampleID’, and ‘sampleFate’ data that are not relevant when no physical sample was collected. 
DP1.10086.001 Soil physical and chemical properties, periodic Several soil samples were flagged as being collected from resampled X, Y locations. Some instances of oven start dates or pH processed dates were removed if they were before the sample collect dates (this was a data entry error). Fall 2021 soil samples from ORNL were flagged to indicate missing pH data. In the long-term summary table for carbon and nitrogen analyses, uncertainty values contain updated metrics that better conform with NEON definitions of uncertainty terms.  
DP1.10111.001 Site management and event reporting All TOS plot values in the 'locationID' field were updated to include the three letter sampling code to work with `geoNEON` functions. 
DP1.20048.001 Discharge field collection Stage and discharge values are now all published in the dsc_fieldData table regardless of measurement type (flowmeter vs. ADCP; measurement type is published in dsc_fieldData:dischargeBoutTypeID). The dsc_fieldDataADCP table is still published and contains the survey metadata and secondary variables. All discharge values are now published in liters per second in the dsc_fieldData:finalDischarge field. Both dsc_fieldData:totalDischarge and dsc_fieldData:totalDischargeCalcQF are no longer published. The staff gauge named location is now published in this data product for each bout in dsc_fieldData:staffGaugeID. Temporary hydrologic conditions at the staff gauge and discharge transect locations are now published in dsc_fieldData (field names: gaugeTempHydroCond, gaugeTempHydroCondLoc, dscTempHydroCond, dscTempHydroCondLoc). For previously released records, data in these fields were migrated from the Gauge height (DP1.20267.001) data product and populated in this data product. The gag_fieldData table is no longer published in this data product. All numeric fields now have consistency in units (all now metric) and fields that report the unit for a measurement or provide a quality flag for inconsistent units are no longer published. All previously released records have been edited to fit the new data product structure.
DP1.20063.001 Aquatic plant bryophyte chemical properties alg_clipHarvest.biophysicalCriteria options have been updated to 'OK - within bout window', 'conditions not met: sampled after fish', and 'conditions not met: outside bout window'.
DP1.20066.001 Aquatic plant bryophyte macroalgae clip harvest alg_clipHarvest.biophysicalCriteria options have been updated to 'OK - within bout window', 'conditions not met: sampled after fish', and 'conditions not met: outside bout window'. 
D01 state-level taxa obfuscation: Prior to the 2024 data release, publication of species identifications were obfuscated to a higher taxonomic rank when the taxon was found to be listed as threatened, endangered, or sensitive by any state within the domain. Obfuscating state-listed taxa across an entire domain has created challenges for data users studying biodiversity.

D01 state-level taxa obfuscation: Prior to the 2024 data release, publication of species identifications were obfuscated to a higher taxonomic rank when the taxon was found to be listed as threatened, endangered, or sensitive by any state within the domain. Obfuscating state-listed taxa across an entire domain has created challenges for data users studying biodiversity.
Reduced sampling: Until 2022, D11 BLUE collected transect data at 0.5 m intervals. Due to the stream width, data collection in one day is difficult especially during times of extreme heat.
DP1.20086.001 Benthic microbe community composition amb_fieldParent.biophysicalCriteria options have been updated to 'OK - within bout window', 'conditions not met: sampled after fish', and 'conditions not met: outside bout window'.

DP1.20288.001 Water quality Chlorophyll data streams were corrected due to the RFU and mg/L units being transposed. A complete list of sites and dates with incorrect data in RELEASE-2023 can be found in the issue log.
DP3.30015.001 Ecosystem structure This data product was updated for all sites and years, using an improved implementation of the pit-free Canopy Height Model. Please see AOP Data Availability Notification – Release 2024 for more details.
DP3.30015.001, DP3.30024.001, DP3.30025.001 Ecosystem structure, Elevation - LiDAR, Slope and aspect - LiDAR Re-processed to remove and re-classify mis-classified noise in the discrete lidar point clouds for CHEQ 2020-08 (delivered under STEI 2020-08) and CLBJ 2018-04. These mis-classified points previously resulted in artifacts in the derived L3 lidar raster products, which are now corrected.
DP4.00001.001 Summary weather statistics Data were reprocessed to incorporate the algorithm changes in primary precipitation (DP1.00006.001).
DP4.00200.001 Bundled data products - eddy covariance The turbulent CO2 concentration (DP1.00034.001) and CO2 flux (DP4.00067.001) field calibration was improved by evaluating variance and removing erroneous gas cylinders from regression and reevaluating to maximize data quality and availability. Flux footprint characteristics (DP4.00201.001) statistics table now includes the stability parameter (z/L) and the Obukhov length (L).The Atmospheric CO2 and d13C variables under the Atmospheric CO2 isotopes data product (DP1.00036.001) are now corrected using the NEONIso package with basic files including the Bowling et al., 2003 correction and expanded files including both Bowling et al., 2003 correction and a linear regression correction (Fiorella et al., 2021).
