5. AMIP OLR (LW), tropical (20S-20N)
   11 models, different realizations
   Folder: ./amip_olr/

6. AMIP OSR (SW), tropical (20S-20N)

IDL programs
--
7. main.pro
    This is the main program calling all procedures, calculating feedbacks, and displaying figures.
    To run this program, IDL> main
    *Important user-defined parameter: flux
     Select LW, SW, or LW+SW at Line 48, Line 168
     The sample figure 'Fig.jpg' is feedback estimates for LW.

8. obs.pro
    This procedure opens all observed data, SST, ERBE&CERE fluxes.

9. amip.pro
    This procedure opens 11 AMIP model outputs (LW, SW fluxes).

10. lc11.pro
    This procedure calculates feedback parameters by Lindzen-Choi method
    as well as simple linear regression.
