Section 10: POSTPROCESSORS<br />

<strong>Table</strong> 10-10 (Continued)<br />

POSTUTIL Control File Inputs - Input <strong>Group</strong> 1<br />

Control Parameters (continued) for HNO3/NO3 repartition<br />

Variable Type Description Default<br />

MNITRAT<br />

E<br />

integer<br />

Option to repartition HNO3/NO3 concentr<strong>at</strong>ions<br />

prior to performing other actions (does not alter<br />

deposition fluxes)<br />

0 = no<br />

1 = yes, for all sources combined (requires<br />

MET.DAT)<br />

2 = yes, for a source group, based on r<strong>at</strong>io <strong>of</strong><br />

species HNO3ALL/NO3ALL<br />

3 = yes, for ALM applic<strong>at</strong>ion in one step<br />

0<br />

NH3TYP integer Option to select the input source <strong>of</strong> Ammonia<br />

(NH3 or TNH3) for either MNITRATE=1 or<br />

MNITRATE=3<br />

0 = Ammonia from concentr<strong>at</strong>ion file is used<br />

alone<br />

1 = Ammonia listed in BCKNH3 or BCKTNH3<br />

will be added to Ammonia from the concentr<strong>at</strong>ion<br />

file<br />

2 = Ammonia from background concentr<strong>at</strong>ion file<br />

BCKGALM will be added to Ammonia from the<br />

concentr<strong>at</strong>ion file<br />

3 = Ammonia listed in BCKNH3 or NCKTNH3<br />

will be used alone<br />

4 = Ammonia from background concentr<strong>at</strong>ion file<br />

BCKGALM will be used alone<br />

BCKNH3 real Background ammonia concentr<strong>at</strong>ion (ppb) used to<br />

repartition nitr<strong>at</strong>es when ammonia is NOT a<br />

modeled species (used only when MNITRATE=1<br />

or 3 and BCKTNH3 is not used)<br />

BCKTNH3<br />

real<br />

Background total ammonia concentr<strong>at</strong>ion (ppb)<br />

used to repartition nitr<strong>at</strong>es when ammonia is NOT<br />

a modeled species (used only when MNITRATE<br />

=1 or 3 and BCKNH3 is not used)<br />

No default<br />
