grads如何打开he5的文件,写成ddf后,
gaophdf error: SDstart failed to open hdf-sds file D:\workspace\lnw\OMI-Aura_L3-OMTO3d_2010m0101_v003-2012m0406t094821.he5
gadsdf: Couldn't ingest SDF metadata.
SDF Descriptor file d:/workspace/lnw/omi.ddf was not successfully opened & parsed.
这个是我写的ddf文件:
dset OMI-Aura_L3-OMTO3d_2010m0101_v003-2012m0406t094821.he5
dtype hdfsds
undef -1.267651e+30
xdef XDim_OMI_Column_Amount_O3 360 linear -179.5 1
ydef YDim_OMI_Column_Amount_O3 180 linear -89.5 1
zdef level 1 levels 1000
tdef time 1 linear 01jan2010 1dy
vars 5
uva=>UVAerosolIndex_OMI_Column_Amount_O 1 99 UVAerosolIndex
rad=>RadiativeCloudFraction_OMI_Column_Amount_O3 1 99 RadiativeCloudFraction

vie=>ViewingZenithAngle_OMI_Column_Amount_O3 1 99 ViewingZenithAngle

endvars
下面是ncl显示的he5的文件信息:

用grads如何处理,我写的ddf文件如何修改?
谢谢!!
