ncl将HE5文件转为NC后，用HDF Explorer打不开

YangJC

我是个初学者，今天转文件格式的时候除了问题，向大神们请教一下。
    fin = addfile("he5\OMI-Aura_L2G-OMTO3G_2017m0131_v003-2017m0201t071837.he5","r")
    o3  = fin->ColumnAmountO3_OMI_Column_Amount_O3
    lat = fin->Latitude_OMI_Column_Amount_O3
    lon = fin->Longitude_OMI_Column_Amount_O3
    sza = fin->SolarZenithAngle_OMI_Column_Amount_O3
   
    system("rm -rf OMI-Aura_L2G-OMTO3G_2017m0131_v003-2017m0201t071837.nc")
    fout       = addfile("OMI-Aura_L2G-OMTO3G_2017m0131_v003-2017m0201t071837.nc","c")
    fout@title = "NetCDF output using method 1"
    fout@creation_date = systemfunc("date")
   
    filedimdef(fout,"time",15,False)
    fout->ColumnAmountO3=o3
    fout->Latitude=lat
    fout->Longitude=lon
    fout->SolarZenithAngle=sza

感觉没有改变数据，但是输出的NC用HDF Explorer打不开，只能用HDFView打开，这是为什么
