Ken, My bad here. I didn't thoroughly read your email. I jump to GOES. Our format is for the imager/sounder data not the other instruments. My apologies, David Wilensky -----Original Message----- From: Ken Tanaka [mailto:Ken.Tanaka@xxxxxxxx] Sent: Monday, May 07, 2007 12:35 PM To: David Wilensky Cc: netcdfgroup@xxxxxxxxxxxxxxxx Subject: Re: Can you recommend a netCDF convention for satellite time series data? Hi David, Yes, I would be interested in seeing the ncdump -h of your format. If it is very large, you can send it to just me rather than the email list. Is your data type a geomagnetic time series?
