***【メモ：強く思ったこと】 [#n9bb19f4]
やはり、同位体はしっかりやらなければいかん。
モデルグループはきちんと（？）みてる。
***【メモ：やるべきこと】 [#p0017f4e]
Regional Model
Ocean Model
Diagnosed 18O subroutine? (Vertical Integration)
川論文->高緯度バイアスをどうするか。CNIP(Gibson)とも比較？
川からの蒸発。Wetland, Lakeの取り扱い。
カップル論文->偏差、観測との比較。
River networkをどうするか。0.5deg?
パタゴニアデータ。
CNIP, USNIP
藤田さんの南極
植村君の船
シェル？
色々と比較するべき。
***Morning 1 B11E [#g2b2f2b3]
8:00 Introduction. J. West, G.Bowen. He is Very young!!
8:00 G. Schmidt.
Coupled model results. Sea surface water del18O is quite
nice to see the model performance than precip del18O or
d-excess.
Mode: air temp, precip amount, del18O, d-excess
2xCO2: Arctic signal-Air Temp-> Stays same
Precip over land: 期間によってP-δP関係が変わる。→困った！
→結局、使えない、という結論か？
8:20 David Noone: 130y-trends
Regarding climate change, precipitation change is not bi...
-> What about isotepes?
SWING: more models welcome!
Model trends:
Africa, N.NA, Indian Ocean, Atlantic: Depletes
Europe: Enriches
Regression with SOI. Center in the middle of Pacific,
Trend をP/E/Aの増減で分析。
時間の都合上か、「実際」の状況が出てこなかったが、どうな...
8:35 J.E. Lee(UCB)
NCAR CAM2-iso model results. (Ocean? Land?)
前の二人に比べるとマダマダか。
8:50 D. Yakir
10-yr vapor isotopes:
Model-Obs differs!
Observation based and local
9:15 L.Sternberg
セルロースとStem Water δ18Oは相関。
セルロースδ13CとstemWaterはアウト。
回帰直線の係数とモデルが良く一致。おどろき。
地理的にはQuite Fitted。時系列はどうなるか？→Next step
9:30 JW White：δ13CH4 1700-2000．
9:50 B. Alexander (UW): Suflate Delta17O
Fire index vs sulfate (nitrate) Delta17O.
