new to netcdf and questions

[Chris Jursa]

Hello,

My name is Christopher.  I am new to the netCDF file format and have some 
questions.

I was given a netCDF file from a colleague and I need to visualize it in 
ArcGIS.  I have ArcGIS 9.2 and I have created a raster image from the 
data.  It is available at 
http://gis.sis.pitt.edu/temp/chris/netCDF/netCDF.JPG  It depicts the O3 
data for the netCDF file.

However, I cannot determine the projection or datum of the data.  I have 
the beginning of the netCDF file at 
http://gis.sis.pitt.edu/temp/chris/netCDF/sample.netcdf.  Where is the 
projection information?

Also, if you look at the image, the coordinate information at the bottom 
left (or southwestern) corner indicates the converted netCDF originates 
from the origin.  Is there any coordinate informtion in the second link 
above or is ArcGIS defaulting the conversion to a 0,0 origin?  I was told 
this data was from the western area of Georgia in the US.  However, 
nothing indicates this to me in the file?

Again, I am looking for coordinate and 
projection information on my file.  I am not sure if it exists or not.


Thank you for your time!

Sincerely,
