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
