CF extensions for satellite data

ESIP Summer Meeting 2012

Possible extensions circa Winter 2011

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

Whittaker proposal for spectral bands

Create two coordinate axis types ("wavelength" and "wavenumber") that can be recognized by the NetCDF library as defining a "spectral coordinate".

Similar to time dimension variable New standard names also needed

center_wavelength, or wavelength center_wavenumber, or wavenumber
