The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃. en-copyright= kn-copyright= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=1 ORCID= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=2 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=3 ORCID= en-aut-name=ChikamoriHidetaka en-aut-sei=Chikamori en-aut-mei=Hidetaka kn-aut-name=近森秀高 kn-aut-sei=近森 kn-aut-mei=秀高 aut-affil-num=4 ORCID= en-aut-name=KurokawaMasahiro en-aut-sei=Kurokawa en-aut-mei=Masahiro kn-aut-name=黒川正宏 kn-aut-sei=黒川 kn-aut-mei=正宏 aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=中嶋佳貴 kn-aut-sei=中嶋 kn-aut-mei=佳貴 aut-affil-num=6 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=3 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=4 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=5 en-affil= kn-affil=岡山大学環境理工学部 affil-num=6 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=7 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=Okayama Local Meteorological Observatory kn-keyword=Okayama Local Meteorological Observatory en-keyword=relocation kn-keyword=relocation en-keyword=drop in air temperature kn-keyword=drop in air temperature END
