Optical lightning sensor research #23

Open originalfoo opened 7 years ago

originalfoo commented 7 years ago

Wavelength to check? ~777nm source (related)

Ball lightning can be detected via same frequency – source

originalfoo commented 7 years ago

Lots of info on optical measurements of lightning, states that there are two main bands to check: 777.4 nm and 886.3 nm

From same source:

7774 and 8683 Angstroms. These are emissions from atomic oxygen and nitrogen respectively (OI and NI denote atomic oxygen and nitrogen)

Great paper on lightning detection (in general) within planetary atmospheres

For CG lightning – source

Likely that each type of lightning has discernible spectra.

For CG strikes, cyanogen spectra (~384.0 nm) indicates continuing current, something known to cause forest fires. Combined with low moisture (dry lightning) and high forest fire index, it would be key warning indicator of risk of fires.

Narrowband filters of 10 Å should be applied for the various spectra of interest. – source
