Lightning assimilation

[beni]

Hello,
I found some interesting article on assimilating lightning data into WRF by nudging water vapor (Qv) and deep convection, showing remarkable results: http://www.nssl.noaa.gov/users/mansell/icae2014/preprints/Fierro_90.pdf
Is there any source code publicly available for this, or are there any similar functions in WRF (or on its roadmap)?
