Re: MISR data processing

Hi Dennis,

By ncl_filedump, I found the following information:
------------------------
      ..............
                GridName="AerosolParameterAverage"
                XDim=720
                YDim=360
                UpperLeftPointMtrs=(-180000000.000000,90000000.000000)
                 LowerRightMtrs=(180000000.000000,-90000000.000000)
      .............
            OBJECT=DataField_3
                   DataFieldName="Optical depth average"
                   DataType=DFNT_FLOAT32
                   DimList=("YDim","XDim")
---------------------------------

The "Optical depth average" is what I need. Sounds YDim and XDim are the variables in MISR:)

Any other suggestions?

Thanks again,
-Lin

I did this when I processed MODIS data, and I got the plot looks perfect! However, when I tried the same methods on MISR data, it always showed error like this:
