A. General Information

Thedata (netcdf format) are calculated using the P-vector inverse method.

Please note that

(1) To read the netcdf data files, you need to install matlab netcdf tools from the websites:

(2) You can use ncbrowser to view and to get the netcdf data

> ncbrowser ****.nc nowrite

(3) We provide a MATLAB function (getFANnc.m) for easily accessing the netcdf data.

For more information, please type

> help getFANnc

B. Data Information
