2017 EarthCube netCDF-CF Workshop
Advancing netCDF-CF for the Geosciences
6-8 September 2017, Boulder, Colorado
Original website hosted at Unidata
This workshop will focus on efforts to advance the Climate and Forecast (CF) metadata conventions for
netCDF (netCDF-CF). The meeting is being hosted by the EarthCube “Advancing netCDF-CF for Geoscience”
project, which is funded by the US National Science Foundation’s EarthCube program.
This workshop is sponsored by the National Science Foundation 
Agenda
Note: All times are in US/Mountain time (GMT-6).
