S. Department of Energy author NSF National Center for Atmospheric Research publisher AmeriFlux [http://ameriflux.lbl.gov/] is part of the larger network Fluxnet [http://daac.ornl.gov/FLUXNET/fluxnet.shtml] which endeavors to connect observations from regional micrometeorological tower sites for global analysis. AmeriFlux towers measure the exchange of energy, water, and carbon through a network of sites with variable vegetation, disturbance records, and climatic conditions. The ecosystems included within the network are temperate and tropical evergreen forests, temperate deciduous forests, woodlands, grasslands, agricultural crops, boreal, and shrublands. Climates in these biomes vary between tundra, temperate, tropical, and arid. This Level 4 Dataset accumulated from the AmeriFlux Network focuses on hourly, daily, and monthly observations collected at North American tower sites. The selection of AmeriFlux sites were chosen based on the period of available data, the diversity in vegetation types, the past success of testing land surface models, and the availability of atmospheric forcing for Community Land Models. AmeriFlux Level 4 data has been gap-filled, quality-flagged and includes meteorological variables, CO2 exchange rates, heat fluxes, biogeochemical pools, calculated gross productivity, and ecosystem respiration terms. The period of record varies by individual tower site, but some sites have as much as 15 years of recorded data. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/AmeriFlux_logo_195_95.png Logo thumbnail from URL png NetCDF dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral MESONET > Mesoscale Meteorological Network U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > TERRESTRIAL ECOSYSTEMS > GRASSLANDS EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > ECOSYSTEM FUNCTIONS > RESPIRATION RATE EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > ANTHROPOGENIC/HUMAN INFLUENCED ECOSYSTEMS > AGRICULTURAL LANDS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > HEAT FLUX EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > TERRESTRIAL ECOSYSTEMS > FORESTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > INCOMING SOLAR RADIATION EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > TERRESTRIAL ECOSYSTEMS > ALPINE/TUNDRA EARTH SCIENCE > BIOSPHERE > ECOLOGICAL DYNAMICS > ECOSYSTEM FUNCTIONS > BIOGEOCHEMICAL CYCLES EARTH SCIENCE > LAND SURFACE > SOILS > SOIL TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SOLAR RADIATION EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION RATE EARTH SCIENCE > LAND SURFACE > SOILS > SOIL MOISTURE/WATER CONTENT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1992-01-01 2008-01-01 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 478.116 https://gdex.ucar.edu/datasets/d387000/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d387000/dataaccess/ https Data Access Related Link download none asNeeded
