The expected time from data and/or sample collection in the field to data publication is one year.
description: A down-looking sonar is used to collect sonar survey data. A dual beam echosounder with side scan sonar and WAAS GPS was used to collect bathymetric (depth) and backscatter (signal strength) data prior to 2019. These data are collected using a boat-mounted system applied during surveys of NEON lakes and river sites. Bathymetric surveys are completed every 5 years at lakes and every 3 years at rivers following 3 consecutive years to verify channel stability; if an extreme event results in substantial changes to the physical environment, then an out-of-cycle survey may be conducted. Sonar data are used to produce bathymetric maps, bottom-type maps, and plant coverage maps. Instrumentation: Humminbird 1198c Si Combo, Humminbird Helix 10 SI, Biosonics MX

title: Periphyton, seston, and phytoplankton chemical properties (DP1.20163.001)
title: RELEASE-2026

description: This data product contains the quality-controlled, native sampling resolution data from NEON's aquatic periphyton and phytoplankton chemical analyses provided by a contracted lab. Benthic and water column field samples are collected in wadeable streams, rivers, and lakes three times per year during the growing season using the type of sampler most suitable to the habitat and substratum types present at the site. Samples are separated into aliquots at the domain support facility and filtered onto glass-fiber filters for chlorophyll, pheophytin, ash-free dry mass (AFDM), carbon, nitrogen, phosphorus, and carbon, nitrogen, and sulfur isotopes for analysis at external facilities. For additional details, see the user guide, protocols, science design, and laboratory SOPs listed in the Documentation section in this data product's details webpage.

description: Periphyton and phytoplankton samples are collected three times per year at wadeable stream, river, and lake sites during aquatic biology bout windows, roughly in spring, summer, and fall. Samples are collected using the most appropriate sampler for the habitat and substratum type, including rock scrubs, grab samples, and epiphyton, and water column samplers for phytoplankton. In wadeable streams, periphyton samples are collected in the two most dominant benthic habitat types (e.g. riffles, runs, pools, step pools). In lakes, water-column phytoplankton samples are collected near the buoy and littoral sensors using a Kemmerer sampler, and in littoral areas using the best benthic sampling method for the substratum type. In rivers, phytoplankton samples are collected near the buoy and two other deep-water locations using a Kemmerer or Van Dorn sampler, and in littoral areas using the most appropriate benthic sampling method for the substratum type. Starting in 2024, field samples are composited by habitat type prior to processing at the domain support facility. All samples (before 2024) and composite samples (2024 and later) are subsampled for various analytes. Subsamples are filtered onto glass-fiber filters then frozen (chlorophyll/pheophytin) or dried (C, N, P, isotopes, and AFDM) and shipped to external analytical facilities for analysis.

title: Elevation of surface water (DP1.20016.001)
title: RELEASE-2026

description: Surface water elevation is controlled by precipitation at both the landscape and channel scales, overland flow, interflow, and groundwater flow. It is correlated to discharge and is critical to understanding how water moves through the environment, carrying nutrients and sediment, modulating aquatic ecosystem structure and function. This data product contains continuous, quality-controlled, surface water depth converted to elevation above mean sea level. Measurements are taken once per minute and reported as 1-minute instantaneous data and 5 and 30-minute averages.

Latency:
Data collected in any given month are published during the second full week of the following month.
description: Elevation of surface water is used to provide continuous discharge measurements in wadeable streams, rivers and lakes where flowing inlet and outlet streams are present. Pressure transducers are located at both the upstream and downstream sensor stations in wadeable streams, at a single station in rivers, and at two littoral locations at lake sites.

title: Albedo - spectrometer - mosaic (DP3.30011.001)
title: RELEASE-2026

description: Albedo, the ratio of a surface’s reflected energy to its incident energy, is an important measurement for characterizing earth system energy balance. Light and dark surfaces correspond to high and low albedo, respectively. An opaque surface’s difference in energy reflected as compared to the energy incident on it is absorbed by the surface, increasing its temperature (Sabins, Jr., 1978). Albedo values depend on wavelength, illumination sources and geometry, sensor viewing geometry, reflectance as a function of angle and wavelength, as well as the scattering, absorbing, and re-radiating effects of the atmosphere. These factors are modeled/accounted for to best approximate a bi-hemispherical reflectance as would be measured in a laboratory setting. To this end, the wavelength-integrated surface reflectance, weighted with the global flux on the ground, is produced as the best practically achievable albedo measurement (Richter & Schlapfer, 2017). L3 Albedo is distributed in 1 km by 1 km tiles created by taking the most-nadir pixels from the flight lines acquired in the best weather conditions.

Latency:
AOP data will be available 60 days after the final collection day at a site. Note: Data for airborne collections in 2022 and 2023 are currently being added to the data portal under a new revision number (DP3.30011.002) since they are derived from BRDF corrected reflectance data, so will not be available here. Albedo derived from directional reflectance will still be available for earlier collections (pre 2022) until they are re-processed with all of the latest reflectance corrections.
description: Albedo data products are derived from NEON Airborne Observation Platform (AOP) Imaging Spectrometer (NIS) data collected in North-South oriented flight lines to reduce BRDF effects. These data are processed to orthorectified directional surface reflectance and then to Albedo as best practically approximated by wavelength-integrated surface reflectance, weighted with the global flux on the ground. L3 Albedo is distributed in 1 km by 1 km tiles at a 1 m spatial resolution. Filenames contain the coordinate of the lower-left (south west) corner of the tile.

title: fPAR - spectrometer - flightline (DP2.30014.001)
title: RELEASE-2026

description: The fraction of photosynthetically active radiation (fPAR) describes the relative quantity of incident solar radiation of relevant photosynthetically active wavelengths (0.4-0.7 microns) absorbed by vegetative material. The fPAR is an important biophysical variable used in the simulation of water, carbon and nutrient cycling due to its relationship with vegetative productivity. Theoretically, if a plant is able to intercept and absorb relevant photosynthetically active wavelengths, this will result in a higher state of productivity, gas exchange and transpiration. The application of this theory is critical in assessments of productivity change through time, and simulation of climate models to predict ecosystems response to climate variability. The Level 2 (L2) version of the fPAR product is distributed by flight line at 1 m spatial resolution.

Latency:
AOP data are expected to be available 60 days after the final collection day at a site. Note: Data for airborne collections in 2022 and 2023 are currently being added to the data portal under a new revision number (DP2.30014.002), so will not be available here. fPAR derived from directional reflectance will still be available for earlier collections (pre 2022) until they are re-processed with all of the latest reflectance corrections.
description: The product includes a fPAR (fraction of photosynthetically active radiation) map and fPAR uncertainty map, both in geotiff raster format by flight line. The fPAR and uncertainty in fPAR maps are derived from the directional surface reflectance, through the intermediate SAVI (Soil Adjusted Vegetation Index) and LAI (Leaf Area Index) products. Rasters are reported with horizontal reference to the ITRF00 datum and projected to the Universal Transverse Mercator (UTM) mapping frame. The fPAR is a unit-less value which describes the fraction of absorbed radiation by plant material.

description: Benthic microbe samples are collected at the same time and location as periphyton (microalgae) samples three times per year in wadeable streams during aquatic biology bout windows, roughly in spring, summer, and fall. Samples are collected using field-sterile methods using the most appropriate sampler for the habitat and substratum type, including rock scrubs, grab samples, and epiphyton. In wadeable streams, periphyton samples are collected in the two most dominant benthic habitat types (e.g. riffles, runs, pools, step pools). Cobble scrubs are filtered on 0.22 um Sterivex capsule filters, capped and flash-frozen in the field. Grab samples of sediment (silt, sand) or plant material/epiphyton are collected when appropriate. All samples are frozen on dry ice in the field and are shipped to an analytical facility for DNA extraction, sample preparation and high-throughput sequence analysis using primer sets targeting the ribosomal RNA gene operon. Laboratory metadata are passed through the NEON automated ingest process for QC testing and are published on the NEON data portal.

title: Secchi depth (DP1.20252.001)
title: RELEASE-2026

description: This data product contains the quality-controlled, native sampling resolution data from NEON's Secchi depth data collection. Secchi measurements indicate water clarity, and secchi depth is used to determine the depth to which light penetrates. This value can also be used to calculate the depth of the euphotic zone in a lake or river, which is especially important for phytoplankton sampling. Secchi data are collected when collecting data for any standard operating procedure that samples the water column in a lake or river (e.g., surface water chemistry and phytoplankton) by lowering a Secchi disk through the water column, and recorded the depth(s) to which it disappears from view. Secchi depth measurements are collected only during ice-free periods, and are collected a minimum of 4 times per year, up to 12+ times per year. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

description: Soil sampling occurs 1-3 times per year depending on length of growing season, with each site always sampled during the historic peak in vegetation greenness. Three pre-determined, randomly assigned locations are selected for each sampling event within each of 10 plots distributed throughout a site; sampling locations within a plot are not re-sampled. Soil samples are collected to a maximum depth of 30 cm, with organic and mineral soils sampled separately. The same samples are used for measurement of soil physical and chemical properties to maintain temporal and spatial connectivity. Subsamples of homogenized soil are either sieved (mineral soils), or picked of coarse debris such as rocks, roots and fresh organic material (organic soils) and 5-10g are transferred to cryo-safe vials. The samples are frozen and shipped on dry ice to an analytical facility, where freeze-drying, PLFA extraction and GC analysis are performed. Laboratory data are passed through the NEON automated ingest process, undergo additional QAQC testing, and quality-checked data are published on the NEON data portal. Instrumentation:
