Dry River Flux Data Release 2025 v2
This release consists of flux tower measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer using eddy covariance techniques. Data were processed using PyFluxPro (v3.4.21) as described by Isaac et al. (2017). PyFluxPro produces a final, gap-filled product with Net Ecosystem Exchange (NEE) partitioned into Gross Primary Productivity (GPP) and Ecosystem Respiration (ER). The site is classified as open forest savanna. The overstory is co-dominated by tree species Eucalyptus tetrodonta, Eucalyptus dichromophloia, Corymbia terminalis, Sorghum intrans, Sorghum plumosum, Themeda triandra and Chrysopogon fallax, with canopy height averaging 12.3 m. Elevation of the site is close to 175 m and mean annual precipitation from a nearby Bureau of Meteorology site measures 895.3 mm. Maximum temperatures range from 29.1 °C (in June) to 37.6 °C (in July), while minimum temperatures range from 14.6 °C (in July) to 24.8 °C (in November). Maximum temperatures vary seasonally by 8.5 °C and minimum by 10.2 °C. The instrument mast is 15 m tall. Heat, water vapour and carbon dioxide measurements are taken using the open-path eddy flux technique. Temperature, humidity, wind speed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation are measured above the canopy. Soil heat fluxes are measured and soil moisture content is gathered using time domain reflectometry. Ancillary measurements taken at the site include LAI, leaf-scale physiological properties (gas exchange, leaf isotope ratios, nitrogen and chlorophyll concentrations), vegetation optical properties and soil physical properties. Airborne based remote sensing (Lidar and hyperspectral measurements) was carried out across the site in September 2008.

Data Release: The effects of wildfire on snow water resources estimated from canopy disturbance patterns and meteorological conditions
공공데이터포털
This data release contains model input and output data associated with a published report (The effects of wildfire on snow water resources estimated from canopy disturbance patterns and meteorological conditions [Moeser, Broxton and Harpold, 2019]) where specific descriptions of the data can be found. The input data are derived from pre- and post-fire aerial LiDAR acquired in June 2010 and May 2012 respectively, for a small basin in the Jemez Mountains, northern, New Mexico. Data were process (analyzed?) to represent forest canopy characteristics pre- and post-fire. These characteristics include, (1) canopy closure, (2) edginess to the north, (3) edginess to the south, (4) leaf area index, (5) maximum tree height, (6) mean distance to canopy, (7) mean tree height, and (8) total gap area. Output includes Snow Water Equivalent (SWE) estimates from the SnowPALM model for pre- and post-fire conditions on a daily timestep between the 1st of September 1981 to the 31st of August 2018. All data are in a gridded format where the lower left hand corner is located at 3979325 north, and 371710 east in UTM Zone 13N with a map datum of NAD83. The grid is comprised of 1000 rows by 1100 columns with a grid cell size of 1m for a total domain size of 1.0km x 1.1km.
Great Western Woodlands Flux Data Collection
공공데이터포털
This dataset consists of measurements of the exchange of energy and mass between the surface and the atmospheric boundary-layer in temperate eucalypt woodland using eddy covariance techniques. The Great Western Woodlands (GWW) comprise a 16 million hectare mosaic of temperate woodland, shrubland and mallee vegetation in south-west Western Australia. The region has remained relatively intact since European settlement, owing to the variable rainfall and lack of readily accessible groundwater. The woodland component is globally unique in that nowhere else do woodlands occur at as little as 220 mm mean annual rainfall. Further, other temperate woodlands around the world have typically become highly fragmented and degraded through agricultural use. The Great Western Woodlands Site was established in 2012 in the Credo Conservation Reserve. The site is in semi-arid woodland and was operated as a pastoral lease from 1907 to 2007. The core 1 ha plot is characterised by Eucalyptus salmonophloia (salmon gum), with Eucalyptus salubris and Eucalyptus clelandii dominating other research plots. The flux station is located in Salmon gum woodland. For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/great-western-woodlands-supersite/ .

Hydro Flow Metrics 2080 (Map Service)
공공데이터포털
This map service represents modeled streamflow metrics from the end-of-century time period (2070-2099) in the United States. In addition to standard NHD attributes, the streamflow datasets include \nmetrics on mean daily flow (annual and seasonal), flood levels \nassociated with 1.5-year, 10-year, and 25-year floods; annual and \ndecadal minimum weekly flows and date of minimum weekly flow, center of \nflow mass date; baseflow index, and average number of winter floods. These files and additional information are available on the project website, https://www.fs.usda.gov/rm/boise/AWAE/projects/modeled_stream_flow_metrics.shtml. Streams without flow metrics (null values) were removed from this dataset to improve display speed; to see all stream lines, use an NHD flowline dataset.,
Alfalfa flux footprint experiment 2021
공공데이터포털
,Four eddy-covariance (EC) sensors were deployed at two heights upwind and within alfalfa plot trials at San Joaquin Valley Ag Science Center. The purpose of the experiment was to evaluate the robustness of flux footprint models under different atmospheric stability conditions. At each of the two locations, an EC sensor was mounted at an unconventionally low height (~1 meter) and a second at a more typical height (~2.5 m). Supplementary sensors were co-located to measure net radiation, soil heat flux, and other parameters necessary to evaluate closure of the surface energy budget. The southeast station was located at the downwind edge of a 2 acre plot trial of irrigated alfalfa, arranged in small blocks. The upwind fetch (with respect to predominant day time wind direction) included less than 100 meters of semi-homogeneous conditions. Soil sensors were duplicated across the alfalfa blocks and inter-block alleys which were irrigated but not planted. The northwest station was located approximately 25 meters upwind of the irrigated alfalfa plot trials in fallow, non-irrigated bare field. Raw 10 Hz infrared gas analyzer and sonic anemometer data, and 30 minute averaged data from other sensors are provided.,Resources in this dataset:,
LBA-ECO CD-06 CO2 Exchange in River Systems Across the Amazon Basin: 2004-2007
공공데이터포털
This data set provides measurements of carbon dioxide flux rates (FCO2), gas transfer velocity (k), and partial pressures (pCO2) at 75 sites on rivers and streams of the Amazon River system in South America for the period beginning July 1, 2004, and ending January 23, 2007. Several fieldwork campaigns occurred between June 2004 and January 2007 in the Amazon River basin, with discharge conditions ranging from low to high flow. The sampled areas span the spectrum of chemical characteristics observed across the entire basin, including, for example, both low and high pH values and suspended sediment loads. There is one comma-delimited data file in this data set.
