The<br>
current development code gives better results than you are obtaining,<br>
but it needs further development. As of now the aerosol type is<br>
decoded so the difference between a MASSMR (Mass mixing ratio) record<br>
of, for example, "Sea Salt Dry" and "Sulfate Dry" is detected and<br>
difference variables are created for each. What is not yet implemented<br>
are two new dimension types: one for aerosol size and one for aerosol<br>
wavelength. Consequently, NCL does not yet distinguish between records<br>
that only differ by the size or wavelength of a specific aerosol type.<br>
<br>
Implementing these new dimensions requires enough new code for the<br>
GRIB2 reader that it will probably not make the impending release of<br>
6.4.0. It is a high priority though and we certainly hope to include<br>
it in the follow up 6.4.1 release.<br>
