CF Cluster

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

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

Agenda:

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. Level 3-specific

Local/solar time

4. Level 2-specific

Orbital parameters/swath geometry

5. Level 1-specific

Calibration tables/engineering parameters

netCDF and ISO

Some ideas about the relationship between the netCDF metadata model and ISO are available. Input on those topics are welcome on the NOAA GEO-IDE wiki or here!

netCDF Templates for in-situ data types

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

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

CF-Aware Tools

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