CF Cluster[edit | edit source]

The CF Cluster has expanded to include consideration of the more general problem of conventions and best practices for documenting scientific datasets in any format using a variety of dialects. This Category includes pages that are relevant to the CF Conventions.

Objectives[edit | edit source]

Propose extensions to the CF naming conventions that are relevant to observational data

Create use cases and interoperability demos that demonstrate the value of CF usage in remote sensing

Provide tutorials at Federation meetings on the use of the CF conventions

Possible CF Extensions[edit | edit source]

1. Spectral bands

Define as dimension rather than coordinate variable

Pre-define band names

Pre-define by wavelength/frequency range

Proposal by Tom Whittaker

2. Data quality

Modifiers such as "percent_cloud_free"

3. Level 3-specific

Local/solar time

4. Level 2-specific

Orbital parameters/swath geometry

5. Level 1-specific

Calibration tables/engineering parameters

6, Cf/Radial

Radial data conventions for radars and lidars

netCDF and ISO[edit | edit source]

Some ideas about the relationship between the [netCDF metadata model and ISO] are available. Input on those topics are welcome.

netCDF Templates for in-situ data types[edit | edit source]

NODC has recently proposed a set of netCDF Templates for in-situ data types. These are important potential extensions to the CF Conventions.

netCDF files with groups[edit | edit source]

Here is a netCDF-4 file created by NDBC which uses groups. The THREDDS link to the dataset is here.

Developing CF standard names for data from ADCPs and current meters[edit | edit source]

Proposing Standard Names for data from Current Meters and Profilers

CF-Aware Tools[edit | edit source]

H4CF Conversion Library- provides CF-compliant access to HDF4 and HDF-EOS2 files
