Im unclear if you plan on putting all of these variations in the same file? My
first choice might be to put them in multiple files. The formats that you seem
1) station data
2) track data
3) station data that occasionally moves.
Our format for this kind of data is here:
which covers 1 and 2. we havent dealt with 3 before, but we can come up with
some variant. these are not part of the CF spec, but we plan to submit them.
perhaps you should look at the above spec, then we can talk some more.

I am over at EOL and am wondering if you are the right person to help
me. I am developing a netCDF file to contain data from irregularly
spaced surface stations. Most of these are fixed with respect to time
(i.e. ASOS stations, etc) but some move continuously with time (ships)
or move intermittently, maybe even just once (as in stations that are
relocated but keep the same station id, or truck mounted stations used
during field deployments which are stationary for a few hours to a few
days, and then move and are stationary again.
I am wondering how best to implement this within a CF compliant netCDF
file. For fixed stations, I currently have:
I can change this to:
but less that 1% of the stations are mobile, so this seems like a huge
waste of space. For example, 2 months worth of 5 minute data = 17280
repetitions of the lat/lon for each fixed station, compared to one
instance of lat/lon in my current model, and I have hundreds of stations
Do you have any suggestions as to how to implement this? Can you point
me at any resources that try to tackle this problem?
I just wanted to check before I reinvent the wheel (-:
Thanks so much,
