Rn is often unavailable from many meteorological datasets. Rn may be estimated from downward solar radiation S↓ assuming Rn/S↓ values. We examined seasonal changes of Rn/S↓ values using 1-year radiation data observed above a coniferous evergreen plantation forest of Cryptomeria japonica. Rn/S↓ showed slight seasonal changes; however, other terms in the PT equation showed large seasonal changes. Thus, we conclude that assuming constant Rn/S↓ for all seasons is valid for this site","subitem_description_type":"Abstract"},{"subitem_description":"Priestley-Taylor 式（PT式）は純放射量Rnの入力を必要とする。しかし，Rnは気象データセットに含まれていないことが多い。Rnがデータセットから得られない場合，Rnと下向き日射量S↓の比を仮定することで，RnをS↓ から推定するという方法が考えられる。本研究では，スギ人工林上で計測されたRnとS↓ のデータから，Rn/S↓ の季節変化を調べた。Rn/S↓ はわずかに季節変化を示したが，その季節変化はPT式のほかの項の季節変化に比べて小さかった。したがって，Rn/S↓を季節によらず一定と仮定することは，本研究の対象とした試験地において妥当であると結論された","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53763","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小松,
