Journal ArticleDOI

TL;DR: There is evidence of significant CH3Cl emission from warm coastal land, particularly from tropical islands, based on a global monitoring study and spot measurements, which show enhancement of atmospheric CH3 Cl in the tropics, a close correlation betweenCH3Cl concentrations and those of biogenic compounds emitted by terrestrial plants, and OH-linked seasonality of CH3cl concentrations in middle and high latitudes.
Journal ArticleDOI
Dynamic carbon dioxide exchange through snowpack by wind-driven mass transfer in a conifer-broadleaf mixed forest in northernmost Japan
Kentaro Takagi,Mutsumi Nomura,Daitaro Ashiya,Hiroyuki Takahashi,Kaichiro Sasa,Yasumi Fujinuma,Hideaki Shibata,Yukio Akibayashi,Takayoshi Koike +8 more
TL;DR: In this article, the authors performed continuous (half-hourly) midwinter measurements of CO2 concentrations in a conifer-broadleaf mixed forest snowpack, and found that concentrations in the snowpack fluctuated significantly as wind speeds varied.
Journal ArticleDOI
Seasonal and interannual variations in carbon dioxide exchange of a temperate larch forest
Ryuichi Hirata,Takashi Hirano,Nobuko Saigusa,Yasumi Fujinuma,Koh Inukai,Yasuyuki Kitamori,Yoshiyuki Takahashi,Susumu Yamamoto +7 more
TL;DR: In this paper, the authors reported 3-year measurements of the net ecosystem CO2 exchange (NEE) over a northern Japan larch plantation forest, using an eddy covariance technique with both open-and closed-path systems.
Journal ArticleDOI
In situ comparison of four approaches to estimating soil CO2 efflux in a northern larch (Larix kaempferi Sarg.) forest
Naishen Liang,Toshie Nakadai,Takashi Hirano,Laiye Qu,Takayoshi Koike,Yasumi Fujinuma,Gen Inoue +6 more
TL;DR: In this article, the results were compared with periodic measurements obtained at the same site with an LI-6400 chamber system and an open-top chamber system, and also with continuous measurements obtained with a soil CO 2 gradient system.
Journal ArticleDOI
CO2 and water vapor exchange of a larch forest in northern Japan
Takashi Hirano,R. Hirata,Yasumi Fujinuma,Nobuko Saigusa,Susumu Yamamoto,Yoshinobu Harazono,Masayuki Takada,Koh Inukai,Gen Inoue +8 more
TL;DR: In this paper, a long-term flux measurement has been started in 2000 at a larch plantation on a flat terrain in Hokkaido, Japan to obtain more information on the CO 2 and energy balances of larch forests.
