Analytic Reflectivity (*REFL*) diagnostic output

[andrewgettelman]

The rain rate (rainrt) used in the analytic reflectivity calculation is never set except to zero.

https://github.com/ESCOMP/PUMAS/blob/master/micro_mg3_0.F90#L3668

The correct formulation would look something like this:

` ! rainrt is the rain rate in mm/hr (rainrt= rflx*3600.) ! reflectivity (dum) is in DBz

    rthrsh=0.0001_r8/3600._r8
    if (rflx(i,k+1).ge.rthrsh) then
       dum=log10((rflx(i,k+1)*3600._r8)**6._r8)+16._r8

`

I will work on figuring out how and when to push this back into micro_m3_0.F90. It needs to go in the PUMAS update, plus whatever master version is in the repo

This was fixed in a recent pumas update
