Dear Jonathan et al:
I am working with Gary on the standard name for lightning radiant energy.
The original proposed standard names (see below) are inextricably associated with the characteristics of the lightning detection algorithm we have employed, including the notion of flashes, groups, and events. A more general (and useful) way to approach this standard name is to simply call out a lightning radiant energy, and then use one or more of temporal and spatial coordinate variables in conjunction with cell_methods and cell_measures to describe the specific characteristics of the lightning radiant energy data variable. As a result, see the following amended proposal:
Standard_name:
lightning_radiant_energy
Definition:
Radiant energy associated with the emission of electromagnetic radiation due to lightning. A coordinate variable of radiation_wavelength, radiation_frequency, or sensor_band_central_wavelength may be specified to indicate that the lightning_radiant_energy applies at specific wavelengths or frequencies.
Canonical units: J
very respectfully,
randy
