However, because of the large point-to-point variability in observed CH4 emissions from the marshes, the range of uncertainties in global estimates of emissions from the marshes is large, and further accumulation of observational data and analysis of the sources of flux variability are required.Kushiro Mire is the largest natural wetland in Japan, stretches to the north of kushiro city in eastern Hokkaido, Japan. To understand CH4 emissions in subarctic marshes located in the mid-latitudes, we measured CH4 fluxes during midsummer using the gradient method in the fen (waterlogged communities dominated by reeds and sedges).Yoshinobu HarazonoInternational Arctic Research Center, University of Alaska FairbanksVisiting Researcher+1-907-474-60162160 Koyukuk DriveFairbanksAlaska99775-7340USAharazono2009gl@gmail.comprincipalInvestigatorAkira MiyataNational Agriculture and Food Research OrganizationNone3-1-3 KannondaiTsukubaIbaraki305-8604Japanmiyata.akira@affrc.go.jpprincipalInvestigatorATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATUREATMOSPHERE > ATMOSPHERIC RADIATION > NET RADIATIONATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATIONATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND SPEEDATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND DIRECTIONLAND SURFACE > SOILS > SOIL TEMPERATURELAND SURFACE > SOILS > SOIL HEAT BUDGETBIOSPHERE > VEGETATION > LEAF CHARACTERISTICS > LEAF AREA INDEX (LAI)ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY > RELATIVE HUMIDITYBIOSPHERE > VEGETATION > CANOPY CHARACTERISTICSNASA / GCMD Keywords Version 10.52008-02-05revisionJP/MEXT/NIPRNASA / GCMD Keywords Version 10.52008-02-05revisionFluxnetNASA / GCMD Keywords Version 10.52008-02-05revisionIRGANASA / 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 FluxCH4 FluxH2O FluxMire: FenPole towerCLIMATE_KOEPPEN: DfbIGBP: WETEddy covariance methodOpen-path systemNIAES:Observation of the Behavior of Greenhouse Gases and Aerosols (1991023235)Gradient methodChamber methodFree KeywordCC BY(http://creativecommons.org/licenses/by/4.0/)engutf8climatologyMeteorologyAtmosphere144.330906144.33090643.10751143.1075111993-12-31T03:00:00Z1998-12-31T02:30:00ZUeyama, M., Takao, Y., Yazawa, H., Tanaka, M., Yabuki, H., Kumagai, T., Iwata.
