WRFDA的namelist.obsproc中record1， record2 和record8参数

齐天笑猴

各位大神，请教一下大家有关WRFDA中namelist.obsproc参数设置问题。谢谢大家啦脚本中有关record1；record2；和record8的说明如下

1. &record1
   
2. ;obs_gts_filename: name and path of decoded observation file
   
3. ;fg_format       : 'MM5' for MM5 application, 'WRF' for WRF application
   
4. ;obserr.txt      : name and path of observational error file
   
5. ;<font color="#ff0000">first_guess_file: name and path of the first guess file, for MM5 application only</font>
   
6. ;gts_from_mmm_archive:  set to .true. if decoded observation file is from
   
7. ;                       NCAR/MMM hsi:/BRESCH/RT/DATA/ccyymm/obs.ccyymmddhh.gz
   
8. /
   
9. 
   
10. &record2
    
11. ;time_window_min = '2007-01-01_23:00:00',: The earliest time edge as ccyy-mm-dd_hh:mn:ss
    
12. ;time_analysis = '2007-01-02_00:00:00', : The analysis time as ccyy-mm-dd_hh:mn:ss
    
13. ;time_window_max = '2007-01-02_11:00:00',: The latest time edge as ccyy-mm-dd_hh:mn:ss
    
14. ; Only observations between
    
15. ;       [time_window_min,time_window_max] will be kept.
    
16. ;
    
17. ; When no first guess as input file:
    
18. ; time_window_min: Beginning of time window (included) as ccyy-mm-dd_hh:mn:ss
    
19. ; time_window_max: End of time window (included) as ccyy-mm-dd_hh:mn:ss
    
20. ; Only observations between [time_window_min, time_window_max] will be kept.
    
21. /
    
22. &record8
    
23. ; For MM5 application, all these parameters, except IDD which is set by user,
    
24. ;     can be found in MM5 TERRAIN namelist
    
25. ; For WRF application, these parameters can be found from WRFSI namelist
    
26. ;     file: wrfsi.nl (see note below).
    
27. ;
    
28. ; IDD:    Domain ID (1=< ID =< MAXNES), Only the observations
    
29. ;         geographically located on that domain will be processed.
    
30. ;         For WRF application with XLONC /= STANDARD_LON, set IDD=2,
    
31. ;         otherwise set 1.
    
32. ; MAXNES: Maximum numbe of domains as needed.
    
33. ; NESTIX: The I(y)-direction dimension for each of the domains
    
34. ; NESTJX: The J(x)-direction dimension for each of the domains
    
35. ; DIS:    The grid size for each of the domains
    
36. ;         <font color="#ff0000">For WRF application, always set NESTIX(1),NESTJX(1), and DIS(1)</font>
    
37. ;         <font color="#ff0000">based on the infomation in wrfinput.</font>
    
38. ; NUMC:   The mother domain ID number for each of the domains
    
39. ; NESTI:  The I location in its mother domain of the nest domain's low left
    
40. ;          corner -- point (1,1)
    
41. ; NESTI:  The J location in its mother domain of the nest domain's low left
    
42. ;         corner -- point (1,1)
    
43. ;         For WRF application, NUMC(1), NESTI(1), and NESTJ(1) are always set
    
44. ;         to be 1.

请问，
（1）record1中，如果我用的WRF（而不是MM5），这里first_guess_file就不用写了吗？但是在record8中，却写着要根据为wrfinput来确定NESTIX(1),NESTJX(1), and DIS(1)，这是不是有些矛盾？
（2）record1中，如果同化的是地面监测站的监测数据，这里是不是应该设置为false.
（3）record2中，这里的time_window_min和time_window_max该如何设置与time_analysis的间隔呢？随意设置吗？间隔1小时，2小时，3小时？均可以？还是要根据获得的同化数据的时间间隔设置？
例如：如果我获得的监测数据是间隔1小时的，这里的time_window_min（time_window_max）和time_analysis的时间间隔就为1小时？
（4）record8中， 如果设置了MAXNES=2或者3，就把按照wrf的的namelist设置下面的参数（NESTIX.......NESTJ ）相应的前2列或3列的数值就可以吧？
