The CF Standards Cluster


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

Get Involved: Monthly Telecons

Next telecon:
Tuesday Jan 31, 2pm ET / 11am PT (rescheduled from two weeks earlier)
Dial: 877-668-4493
Access code: 23138379
HDF-EOS / CF Conversion Table
Summer Meeting Plans/ Technical Workshop showing CF-aware tools
CF extensions needed for Level 1, Level 2, and Level 3 data
Minutes of past telecons/meetings:

Possible CF Extensions

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. Node
4. Level 3-specific
Local/solar time
5. Level 2-specific
Orbital parameters/swath geometry
6. Level 1-specific
Calibration tables/engineering parameters

CF-Aware Tools
