【思ったこと】
 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】
 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 big as vapor and temprature.
 -> 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、どうなのだろうか。

 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.
 GEOS-Chem global 3D chemical transport model (CTM)

 [Break]
 John Gibson, Davidと会話。Assimilationをやっている人を紹介。

***Morning 2 B12 [#h1271fa0]
 10:20 Hasting: Delta17O in Nitrate
 
 DeltaNO2=alpha x DeltaO3
 Model is bad in North Pole and South pole. 
 But, delta17O in NO3 itself is amazing 

 H12
 10:40 Y Yi: Lake
 deltaE is important. Huum...

 B12 
 11:05 C. Kendall
 here, lots of data! -> I should use them.
 Horizontal distribution, 
 Down-Upstream profile
 Seasonal variation.

 11:20 JJ Gibson: Lake
 Site specific hydrologic control for aquatic on a lake-by-lake basis.
 Demonstrates that hydrologic variability can be a major influence on aquatic cyctem sensitivity.
 
 Higher risk of acidification in water bodies disconnected from regional runoff theses are isotopically detectable.

*** Afternoon 1 [#o073e177]
 13:00- Poster
 JPL John (Aura HDO)
 Gab Bowen
 Sodemann
 David CIRESに行くのもあり。

 ワインの同位体、水道水

*** Evening [#ac0590f8]
 18:00- Dinner at Fisherman's wharf with Oki, Taniguti
