Water caltrop (Trapa japonica Flerow,a floating-leaved plant) and Esthwaite waterweed (Hydrilla verticillata (L.f.) Royle, a submerged plant) grow along the lake shores during summer, although there were no emergent macrophytes near the observation site.The prevailing wind direction for this site is between west-north-west and north-west.
The turbulent fluxes of sensible heat, latent heat, CO2, and CH4 were measured using the eddy covariance system.Hiroki IwataDepartment of Environmental Science, Faculty of Science,Shinshu University+81-263-37-25023-1-1 AsahiMatsumotoNagano390-8621Japanhiwata@shinshu-u.ac.jpprincipalInvestigatorATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATUREATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > WATER VAPORATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND SPEEDATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > WIND DIRECTIONATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATIONATMOSPHERE > ATMOSPHERIC RADIATION > LONGWAVE RADIATIONLAND SURFACE > SOILS > SOIL TEMPERATUREATMOSPHERE > ATMOSPHERIC PRESSURE > ATMOSPHERIC PRESSURE MEASUREMENTSNASA / GCMD Keywords Version 10.52008-02-05revisionJP/MEXT/NIPRNASA / GCMD Keywords Version 10.52008-02-05revisionFluxnetNASA / GCMD Keywords Version 10.52008-02-05revisionCO2 ANALYZERSCampbell Scientific CR3000NASA / 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 methodOpen-path CO2/H2O analyzerCLIMATE_KOEPPEN: DfcIGBP: WATPole towerCH4 FluxLakeFree KeywordCC BY(http://creativecommons.org/licenses/by/4.0/)engutf8climatologyMeteorologyAtmosphere138.108353138.10835336.04657236.0465722014-12-31T03:00:00Z2023-12-31T02:30:00ZUeyama, M., Takao, Y., Yazawa, H., Tanaka, M., Yabuki, H., Kumagai, T., Iwata.
