Understand the limited and problem of data (data correction)
Find right data to reanalysis for your study
1.Reanalysis data:
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
2.Station data:
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

15. Data share
NCEP :U and V and SST
Period: 1949~now
ERA40:

16. Data seat effect the data’s QC
Compare the data with other country for QC??? (hard)

17. 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

18. Composite’s problem Case by case Composite
Composite will get error message by some of strong case

19. Decadal and global warming
It is hard to separate the decadal and global warming effect by analysis the OBS. Data.
