问题：通过q ctlinfo得到的维度分布写的ctl有误？

酒国

1.直接用sdfopen打开nc。

ga-> sdfopen /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc

Scanning self-describing file:

  /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc

SDF file /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc is open as file 1

LON set to 0 360

LAT set to -90 90

LEV set to 0 0

Time values set: 1850:1:16:0 1850:1:16:0

2.查看维度等情况。

ga-> q ctlinfo

dset /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc

title UNSET

undef 1e+36

xdef 144 linear 0 2.5

ydef 96 linear -90 1.89474

zdef 1 linear 0 0

tdef 156 linear 00Z16JAN1850 12mo

vars 2

aodabs 0 -999 Aerosol absorption optical depth 550 nm

aodvis 0 -999 Aerosol optical depth 550 nm

3.显示变量，可以显示。

ga-> d aodvis

Contouring: 0.05 to 0.6 interval 0.05

1.打开ctl。

Ctl如下：

dset /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc

title UNSET

undef 1e+36

xdef 144 linear 0 2.5

ydef 96 linear -90 1.89474

zdef 1 linear 1 1

tdef 156 linear 12Z14FEB1850 12mo

vars 2

aodabs 0 -999 Aerosol absorption optical depth 550 nm

aodvis 0 -999 Aerosol optical depth 550 nm

Endvars

ga-> open /data3/zhouhb/models/AOD.ctl

Scanning description file:  /data3/zhouhb/models/AOD.ctl

Data file /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc is open as file 1

LON set to 0 360

LAT set to -90 90.0003

LEV set to 1 1

Time values set: 1850:2:14:12 1850:2:14:12

2.查看维度等分布。显示的也直接用sdfopen打开nc文件是一样的。

ga-> q ctlinfo

dset /data3/zhouhb/models/RegCM/RegCMcase/TRS/DATE/B20TRC5/AER/AOD-01a.nc

title UNSET

undef 1e+36

xdef 144 linear 0 2.5

ydef 96 linear -90 1.89474

zdef 1 linear 1 1

tdef 156 linear 12Z14FEB1850 12mo

vars 2

aodabs 0 -999 Aerosol absorption optical depth 550 nm

aodvis 0 -999 Aerosol optical depth 550 nm

3.显示变量，错误。

ga-> d aodvis

Contouring: -nan to -nan interval inf 这个语句有说缺省问题，但这个nc通过q ctlinfo直接有缺省值：undef 1e+36。

估计是你自己编写的描述文件在变量那一块格式有问题吧
