Section 8: CALMET Model Files<br />

<strong>Table</strong> 8-3 (Continued)<br />

Sample CALMET Control File (CALMET.INP)<br />

Input <strong>Group</strong> 6<br />

2 = No surface or upper air observ<strong>at</strong>ions<br />

Use MM5/M3D for surface and upper air d<strong>at</strong>a<br />

(only if NOOBS = 0,1,2)<br />

Interpol<strong>at</strong>ion type<br />

(1 = 1/R ; 2 = 1/R**2) Default:1 ! IRAD = 1 !<br />

Radius <strong>of</strong> influence for temper<strong>at</strong>ure<br />

interpol<strong>at</strong>ion (TRADKM) Default: 500. ! TRADKM = 500. !<br />

Units: km<br />

Maximum Number <strong>of</strong> st<strong>at</strong>ions to include<br />

in temper<strong>at</strong>ure interpol<strong>at</strong>ion (NUMTS) Default: 5 ! NUMTS = 5 !<br />

Conduct sp<strong>at</strong>ial averaging <strong>of</strong> temper<strong>at</strong>ures<br />

(IAVET) (0=no, 1=yes) Default: 1 ! IAVET = 1 !<br />

(will use mixing ht MNMDAV,HAFANG<br />

so make sure they are correct)<br />

Default temper<strong>at</strong>ure gradient Default: -.0098 ! TGDEFB = -0.0098 !<br />

below the mixing height over<br />

w<strong>at</strong>er (K/m) (TGDEFB)<br />

Default temper<strong>at</strong>ure gradient Default: -.0045 ! TGDEFA = -0.0035 !<br />

above the mixing height over<br />

w<strong>at</strong>er (K/m) (TGDEFA)<br />

Beginning (JWAT1) and ending (JWAT2)<br />

land use c<strong>at</strong>egories for temper<strong>at</strong>ure ! JWAT1 = 55 !<br />

interpol<strong>at</strong>ion over w<strong>at</strong>er -- Make ! JWAT2 = 55 !<br />

bigger than largest land use to disable<br />

PRECIP INTERPOLATION PARAMETERS<br />

!END!<br />

Method <strong>of</strong> interpol<strong>at</strong>ion (NFLAGP) Default = 2 ! NFLAGP = 2 !<br />

(1=1/R,2=1/R**2,3=EXP/R**2)<br />

Radius <strong>of</strong> Influence (km) (SIGMAP) Default = 100.0 ! SIGMAP = 100. !<br />

(0.0 => use half dist. btwn<br />

nearest stns w & w/out<br />

precip when NFLAGP = 3)<br />

Minimum Precip. R<strong>at</strong>e Cut<strong>of</strong>f (mm/hr) Default = 0.01 ! CUTP = 0.01 !<br />

(values < CUTP = 0.0 mm/hr)<br />
