Hi John,

I almost finish the new NetCDF files.
Can you please have a look at head.txt before I send them to our ftp server.
I can send you one NetCDF file if you need.

Thank you!

Hi Richard, Chunying:

Ken Richards at environcorp is trying to read the netcdf files at
ftp://eclipse.ncdc.noaa.gov/pub/OI-daily-v2/NetCDF/2004/AVHRR-AMSR

and having trouble. in looking at the file global attributes:

 :title = "Daily-OI-V2, final, Data (Ship, Buoy, AMSR-E, AVHRR, GSFC-ice)";
 :History = "Version 1.0";
 :creation_date = "2008-10-16";
 :Description = "Reynolds, et al.(2007) Daily High-resolution Blended Analyses. 
Available at
ftp://eclipse.ncdc.noaa.gov/pub/OI-daily/daily-sst.pdf  Climatology is based on 
1971-2000 OI.v2 SST,
Satellite data: AMSR Navy NOAA17 NOAA18 AVHRR, Ice data: GSFC ice";
 :Source = "NOAA/National Climatic Data Center";
 :Contact = "Dick Reynolds, email: address@hidden & Chunying Liu, email:
address@hidden";
 :netcdf_Convention = "COARDS";

The problem is that

 :netcdf_Convention = "COARDS";

should be

 :Conventions = "COARDS";

is it possible for you to change this? thanks.
