data Problem Future
ERA40 NCEPR2
assimilation technique, obs data change (satellites)
improve assimilation technique
GPCP not long enough, satellites change combine Station data
SODA Ocean obs data is too poor more Station data
1.Reanalysis data:
2.Station data:
•Obs:
data Problem Future
Temperature
Rainfall
station move auto-observations machine, added satellites data
Hydrography space resolution not enough more satellites
Satellites no long enough more satellite
•Understand the limited and problem of data (data correction) •Find right data to reanalysis for your study
Thanks for your attention!
Data share
NCEP :U and V and SST Period: 1949~now
ERA40:
Data seat effect the data’s QC
Compare the data with other country for QC??? (hard)
method
EOF
We can use the digital filter to decompose different time scale from datasets.
SVD reconstruction
Compare the time serious to separate the different period.
Model simulation can help us to analysis
Composite’s problem
Case by case Composite
Composite will get error message by some of strong case
Decadal and global warming
It is hard to separate the decadal and global warming effect by analysis the OBS. Data.
