incorporate the impact of O₂ concentration on fuel flammability to address the fire overestimation in Tibet:
(1) Add:
forc_po2 => atm2lnd_inst%forc_po2_grc , & ! Input: [real(r8) (:) ] O2 partial pressure (Pa)

(2) fire_m should be changed to:
fire_m = ((afuel*arh30+(1._r8-afuel)*arh)**1.5_r8) &
*((1._r8-btran_col(c)/wtlf(c))**0.5_r8) &
*min(1._r8, max(0._r8, (forc_po2(g)-15000)/2500._r8))

@samsrabin, don't forget to update the parameter file in /glade/derecho/scratch/fangli/firedata. I'm not sure how you update the parameter file. Do I need to list the parameters I've modified, or does your system automatically identify the changed parameters and replace them?

Yep! I've done that as described here. The new parameters will be brought in sometime over the next week.
