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!

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.
