Hello again,
It has been pointed out to me that in the current SeaDataNet format
specification (written and updated by me!) that the initial position of
insisting upon depth for the z co-ordinate was relaxed to allow either pressure
or depth. So, I guess we need to be relaxed and leave z
Hi Andrew -
I am not sure if I should have TEMPERATURE and SALINITY arrays with 4
dimensions
like TEMPERATURE(TIME,LATITUDE,LONGITUDE,PRESSURE) or just 1 dimension
like I have above i.e. TEMPERATURE(PRESSURE). ?
While we don't store profile data in OceanSITES, we are working on our
Dear Andrew and Nan
If your pressure isn't monotonic, and so can't be a coordinate
variable, I don't know
whether it's preferable to demote ALL the coordinates to auxiliary
coordinate variable
status,
TEMPERATURE: coordinates = TIME,PRESSURE,LATITUDE,LONGITUDE ;
I don't think there's a
Dear Karl
I am not quite sure if I have understood you. I have changed ticket 85 to
propose the following for sect 9.6:
Wherever there are unused elements in data storage, the data variable and
all its auxiliary coordinate variables (spatial and time) must contain missing
values. This situation
Hi.
A colleague of mine has told me that if you use size-1 array for a
variable, then data servers such as THREDDS can aggregate the variable over
multiple files and deliver a single file in which the variables will be
arrays of size 1. He said that if a variable is a scalar, THREDDS won't
do
Hi,
I think Jim is talking about NCML (virtual) aggregation. THREDDS can
aggregate even when the variable is a scalar using joinNew. But I
think THREDDS can aggregate only over regular arrays. That is, all the
dimensions other than over which a variable is aggregated should be of
same size
Hi all:
Lets see, I havent followed the entire conversation, but:
1) Andrew if you can send me a sample file (not just the CDL) I can
check if it works in the CDM with the new 1.6 conventions, and maybe
give you some advice from my POV.
2) Aggregation in the CDM comes in 2 flavors. 1) The
Hi Thierry,
Thank you for this information. These netCDF examples and documentation
are excellent. I was able to visualise (vertical cross section of Temperature
,Salinity)
the Pheidippides glider netCDF data with the ncBrowse tool OK.
Regards,
Andrew

Hi Jonathan,
Thanks, for your reply and from others in the CF community.
I certainly have had lots of responses on this topic, all useful information.
I appreciate your deep knowledge of the CF standard which often
clarifies the best way to do things.
Actually I am not 100% clear about use of
Hi Upendra and Jim,
Thanks for answering my questions about capabilities of the viewing sofware
e.g ncBrowse and also the ideas around aggregation.
A NCML enhancement to allow aggregation of different sized depth/pressure arrays
could
be very useful for ocean profile data from e.g. CTD, ARGO,
