Asian dust aerosol data to be displayed in GrADS

[Colarco, Peter R. (GSFC-6133)]

Jason-

I agree the website you are pointing to seems not to be behaving properly.  That's being look at.

But I'm confused about what you want.  This web site points to output from a chemical transport model.  Although we try to make our simulations as realistic as possible, it is not the same as real "data" from a satellite or other observing system.

If (as you seem to indicate) you're looking for satellite data (TOMS, MODIS, etc.) I would suggest you start with the Giovanni web site:
http://daac.gsfc.nasa.gov/giovanni/

They provide downloadable, Grads read (I think) files of a number of satellite data sets.

I just need to find access to TOMS, MODIS, ACE data which shows dust/sulfate aerosols.  I do not care which data set it is.  I tried using the GODDARD data and it would not display in GrADS becuase of some time compatibility issue.  The website for this is:

http://portal.nccs.nasa.gov/cgi-lats4d/webform.cgi?&i=GEOS-5/yotc/0.25_deg/assim/inst3_3d_aer_Nv

What other data sets are available.  Unfortunately, I am running grads from a Windows based PC and do not have much of any resources to use in which to produce fortran programs for reformatting data sets (I am trying to get linux configured on my computer) so I need to access ready to use data in netcd format.  I am trying to display this with NCEP data, which has time steps ending on 0 hours Z, therefore, I need to aerosol data that way.  I currently have aerosol data from the above website but unfortunately it ends on 3 hours z.  How am I able to modify this file given my computational resources at the moment?  Is it possible to do so?  Anyway, please help me out with this.  Anyway, help would really greatly be appreciated, whether in the form of using the above website, modifying the file I have, or accessing ready to use aerosol files.  Again I am trying to examine aerosol files from both Asia and also southern California.

Thanks,

Jason
