Hi Roy,
I am accessing the file using Ferret with the command
use
"http://tds.hycom.org/thredds/dodsC/GLBa0.08/expt_90.8/2010<http://tds.hycom.org/thredds/dodsC/GLBa0.08/expt_90.8/2010.html>
"
where this URL is from the web page
http://tds.hycom.org/thredds/GLBa0.08/expt_90.8.html?dataset=GLBa0.08/expt_90.8/2010
This mode of access from ferret implies (I believe) that I am accessing the
netCDF version. I then define variables to point to one set of vertical
profiles at x=894, y=2020 (and depth levels 1:32) then step in time writing
U,V to a netCDF file that I will process later.
This process typically works fine and it did for the entirety of another
dataset in the same experiment and for this one until timestep 99 when the
error message appeared. Jumping ahead to timestep 121 the process works
from there to the end (step 365). I haven't yet determined when the good
behavior resumes but strangely if I do an ASCII listing across the problem
area (Z level by Z level) the numbers look recoverable.
So from my point of view the problem is not huge and I can work around it
with some effort. Hope this helps you track down the issue so it can be
resolved for other users for whom a workaround is not an option.
Thanks to both you and Nathan for the prompt response.
Mick
