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.
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.
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.
Dr. Nyeema Harris, Assistant Professor at the University of Michigan, discusses her work in conservation biology with lions and large carnivores, community ecology, urban ecology, and global change biology. Her work has given her the opportunity to share access to ecological study with more women and people of color.
The Airborne Remote Sensing Data Quality Technical Working Group recently made a series of recommendations for changes to the NEON AOP data product catalog. These changes included data product name changes, as well as suspension of a subset of AOP products.
The Great Basin (Domain 15) is also home to the iconic Great Salt Lake, expansive salt flats, and rugged hills and canyons. The NEON program is monitoring changes in the desert ecosystems resulting from warming temperatures, decreased snowpack, and human activity.
How much of the water that enters terrestrial systems is used by plants for growth, and how much simply escapes back into the atmosphere unused? Chris Adkison, a researcher at Texas A&M University, used data from the NEON program to compare the accuracy of different methods of partitioning evaporation and transpiration in a Texas oak woodland.
Battelle is testing applications of DAS technology at a National Ecological Observatory Network (NEON) program ecological field site. The Battelle-led and funded study leverages NEON infrastructure and data analytics expertise from Los Alamos National Laboratory (LANL) to test new applications of a DAS technology.
A new study published in Nature Geoscience uses soil from NEON field sites across the continent to look for insights into how climate and ecosystem variables impact the formation and composition of SOM.
Dr. Ana Bento, assistant professor in the School of Public Health at Indiana University, talks about her work in infectious diseases and microparasitic infections and how it has taken on new meaning during the pandemic.
NEON has completed development of an in-house data processing pipeline to generate the microbial community composition data products and has completed optimization of the parameters to be used in the data processing pipeline. Data reprocessing is expected to begin in mid-October.
On 8/13/20, we announced some impending changes to OS biogeochemistry data products. As of today, those changes are complete. Read more to learn about how to access these data. We hope this improves the overall user experience for NEON terrestrial biogeochemistry data products.
A subset of data in the Plant presence and percent cover data product ( DP1.10058.001) did not process correctly through the data pipeline, and were missing from published data. As of September 30, 2020, the missing records have been restored.
With field sites at the Disney Wilderness Preserve, The Jones Center at Ichauway, and the Ordway-Swisher Biological Station, NEON's Southeast Domain provides a model for collaboration between industry, academia, and large-scale research infrastructures to further ecological and conservation research.
Dana Chadwick, post-doctoral research fellow at Stanford University, shares her experiences with mentorship, both as a mentee and as a source of support for her own students, and describes the importance of research opportunities around the world for building important skill sets.
A fix was developed for the issue of missing atmospheric pressure corrections for the soil CO2 concentration data product (DP1.00095.001). All data have now been republished and are available on the NEON Data Portal.
All water chemistry external lab data have been transformed from wide format to long format; the "externalLabData_pub" table has been replaced with the "externalLabDataByAnalyte_pub" table.
From the mountains of Maine to the streets of Manhattan, the Northeast (Domain 01) contains something for everyone. The Domain features a variety of natural habitats as well as some of the largest and oldest urban areas in the U.S. The NEON field sites in Massachusetts and New Hampshire provide opportunities to study how these ecosystems are responding to pressures from climate change, invasive species, and human activities.
Arbuscular mycorrhizal (AM) fungi are found in nearly every ecosystem, quietly helping plants absorb nutrients from the soil. Dr. Bala Chaudhary wants to build a better model of how these vital ecosystem players disperse across the continent. She is using NEON’s Assignable Assets program to examine the role of aerial dispersal in AM fungal movement.
Dr. Zachary Kayler, an assistant professor in the Department of Soil and Water Systems at the University of Idaho, used NEON soil samples to test the ability of a widely-used soil health metric to detect changes from an extreme weather event - Hurricane Maria - in Puerto Rico.
Sites flown in 2017 did not have a uniform QAQC document available for the L3 tiles – a data quality measure implemented at the start of the 2018 flight season. As of August 19, 2020, these data have been corrected and available for download.
In order to improve usability of the Observational System terrestrial biogeochemistry data products, we are repackaging several data products to deliver all of the relevant data for sample sets in one download. We hope this improves the overall user experience for NEON terrestrial biogeochemistry data products.
NEON has begun the process of reconfiguring the multisondes to report DO % saturation relative to local atmospheric pressure, which will be published as a new parameter in the water quality data product. In the interim, NEON has developed the localPressureDO R-package.
