Surface flux measurements by eddy correlation technique during FIFE

This dataset includes the following measurements made over a managed lawn at Fort Logan Cemetery in Denver Colorado in 2011 and 2012. (No measurements were made in winter months: December, January, February). 1) half hourly eddy covariance measurements of evapotranspiration and fluxes of carbon dioxide and sensible heat 2) half hour averages of solar and net radiation, air temperature and humidity, soil temperature, moisture, and heat flux, and half hour sums of precipitation. 3) approximately weekly measurements of vegetation: leaf area index, height of vegetation, dry and wet weights

FIFE observations of surface fluxes

Areal average evapotranspiration by measuring & modeling surface controls

This dataset provides airborne eddy covariance (EC) fluxes of carbon dioxide, methane, sensible heat, and latent heat at high spatial resolution collected during the NASA Carbon Airborne Flux Experiment (CARAFE) airborne 2016 and 2017 campaigns. CARAFE utilized the NASA C-23 Sherpa aircraft with a suite of commercial and custom instrumentation. Deployment occurred across the Mid-Atlantic Region for the period 2016-09-07 through 2016-09-26 and 2017-05-03 through 2017-05-26. The data also include downwelling radiation, water vapor, pressure, temperature, wind, and aircraft navigation data. Airborne EC can quantify surface fluxes at local to regional scales, potentially helping to bridge gaps between top-down and bottom-up flux estimates and offering novel insights into biophysical and biogeochemical processes.

,The Southern Great Plains 1997 (SGP97) Hydrology Experiment originated from an interdisciplinary investigation, "Soil Moisture Mapping at Satellite Temporal and Spatial Scales" (PI: Thomas J. Jackson, USDA Agricultural Research Service, Beltsville, MD) selected under the NASA Research Announcement 95-MTPE-03. The temporal coverage for this dataset is as follows: Begin datetime: 1997-06-01 00:00:00, End datetime: 1997-07-31 23:59:59. The Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) program operates a network of 12 Energy Balance Bowen Ration (EBBR) stations at its Southern Great Plains site. EBBR provides 30-min observations of latent and sensible heat flux along with net radiation, atmospheric pressure, bowen ratio, wind speed and direction, and the following parameters at five locations surrounding the sites: soil moisture, soil temperature, soil heat flow, soil heat capacity and soil heat flow at the surface. The Energy Balance Bowen Ratio (EBBR) system is a ground-based system using in situ sensors to estimate the vertical fluxes of sensible and latent heat at the local surface. EBBR systems will be installed at up to 15 grassland locations within the SGP CART Site. Flux estimates are made from observations of net radiation, soil heat flow, and the vertical gradients of temperature and relative humidity; these data are used in the Bowen ratio energy balance technique.,

VIC grid polygons represent the Variable Infiltration Capacity (VIC) model spatial discretization of input forcing parameters (precipitation, temperature, wind speed), physical parameters (land use, soil, elevation, etc.), and simulated hydrologic parameters (snow water equivalent, runoff, baseflow, etc.) on a 1/16th degree (nominal 6km by 6km) spatial resolution. Each polygon represents the location of where a set of computations occur throughout the simulation period. Input parameters and physical parameters are defined by the modeler and used to calculate the simulated hydrologic parameters. The grid was defined to cover the entirety of California and any watershed area that contributes runoff or baseflow to California for the purpose of estimating unimpaired runoff and baseflow. The model grid was used for modeling activities and climate change analyses for the California Water Commission (CWC) Prop 1 Water Storage Investment Program (WSIP). It is also being provided by the DWR Sustainable Groundwater Management Office for use in SGMA compliance. This spatial dataset does not include any of the model inputs or results. It serves as an index layer that can be linked to a database table of model results from the same model discretization. The VIC model software was developed and maintained by University of Washington with other research collaborators including Scripps Institute of Oceanography. It is a semi-distributed water and energy balance model. More Information about the model can be found at the CWC WSIP Application Resources Page. https://cwc.ca.gov/Pages/ApplicationResources.aspx Information about the related model results are available on the SGMO Data and Tools Page https://www.water.ca.gov/Programs/Groundwater-Management/Data-and-Tools
