The dominant species of this deciduous broadleaf forest is Konara oak, red-leaved hornbeam, japanese sweetspire and Ilex macropoda. Litters from this forest are unusually collected sometime in January to be used in nearby farms as compost. Therefore the forest floor is bared from spring to summer season. Another characteristic of this site is artificial disturbance. There is a local street cuts across the forest and an automobile expressway, Kan-Etsu Dou is only 500m away from the forest. From 1995 to 2002, we have carried out a continuous observation of CO2 and energy budget to clarify the influence of forest onto climate and to collect fundamental data for modeling study.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.Yukio YasudaForestry and Forest Products Research Institute+81-29-873-32111 MatsunosatoTsukubaIbaraki305-8687Japanyassan@affrc.go.jpprincipalInvestigatorATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATUREATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY > RELATIVE HUMIDITYATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND SPEEDATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND DIRECTIONATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATIONATMOSPHERE > ATMOSPHERIC RADIATION > LONGWAVE RADIATIONATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNTLAND SURFACE > SOILS > SOIL MOISTURE/WATER CONTENTLAND SURFACE > SOILS > SOIL TEMPERATURELAND SURFACE > SOILS > SOIL HEAT BUDGETATMOSPHERE > ATMOSPHERIC RADIATION > NET RADIATIONNASA / GCMD Keywords Version 10.52008-02-05revisionJP/MEXT/NIPRNASA / GCMD Keywords Version 10.52008-02-05revisionFluxnetNASA / GCMD Keywords Version 10.52008-02-05revisionCO2 ANALYZERSNASA / GCMD Keywords Version 10.52008-02-05revisionFixed Observation StationsGround-Based ObservationsNASA / GCMD Keywords Version 10.52008-02-05revisionCONTINENT > ASIA > EASTERN ASIA > JAPANNASA / GCMD Keywords Version 10.52008-02-05revisionWorld > Asia > Eastern Asia > JapanISO3166-1 Country codesClimate ChangeBiodiversity and Ecosystem SustainabilityWater Resources ManagementGEOSS themes V2CO2 FluxH2O FluxEddy Covariance methodUpward/Downward PPFDDownward Short-wave Radiation below CanopyFFPRI:Forestry and Forest Products Research InstituteCLIMATE_KOEPPEN: CfaIGBP: DBFFree KeywordCC BY(http://creativecommons.org/licenses/by/4.0/)engutf8climatologyMeteorologyAtmosphere139.486900139.48690035.87250035.8725001996-12-31T03:00:00Z2002-12-31T02:30:00ZUeyama, M., Takao, Y., Yazawa, H., Tanaka, M., Yabuki, H., Kumagai, T., Iwata.
