Dear John,

 

I confirm that 'surface_backwards_scattering_coefficient_of_radar_wave' may 
certainly fit your needs. As you will notice it is expressed with "1" as units, 
instead of dB, because dB are not literally considered as units and then are 
not available in UDUNITS package.

 

Best regards,

 

Olivier

Objet : [CF-metadata] sigma_naught

 

Dear all,

Radar Scatterometers, such as QuikSCAT, are used to measure the winds over the 
oceans, Arctic and Antarctic ice age, track icebergs, among other things by 
measuring a value called sigma naught, also known in the radar community as the 
normalized radar cross-section or backscatter coefficient. Due to a significant 
effort to reprocess multiple sigma naught datasets to netCDF format, which 
shall be hosted at the Physical Oceanography Distributed Active Archive Center 
(http://podaac.jpl.nasa.gov <http://podaac.jpl.nasa.gov/> ) for public 
distribution, I propose the following standard_name definition be added to the 
CF standard name:

 

standard_name:

sigma_naught

 

Definition:

sigma_naught refers to the normalized radar cross section, also known in the 
microwave remote sensing community as the backscatter coefficient. 

 

Canonical Units:

dB

 

 

Sincerely,

John Niedfeldt
