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 Olivier Lauret Project Engineer, CLS Satellite Oceanography Division, Environmental Applications Dept.

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 Cliquez ici <https://www.mailcontrol.com/sr/O5A9qlLg01PGX2PQPOmvUo1yZ91kITL4R1GmgrpUUXx7JobVrilvcQUwJcb25m66tWvdLlniDWOJRcENOpaP7A==> si ce message est indésirable (pourriel).
