Variable Type Description
1 PRES integer Pressure (in millibars)
2 Z integer Elevation (meters above m.s.l.)
3 TEMPK integer Temperature ( o K)
4 WD integer Wind direction (degrees)
5 WS real Wind speed (m/s)
6 w W real Vertical velocity (m/s)
7 q RH integer Relative humidity (%)
8 q VAPMR real Vapor mixing ratio (g/kg)
9 c * CLDMR real Cloud mixing ratio (g/kg)
10 c * RAINMR real Rain mixing ratio (g/kg)
11 i * ICEMR real Ice mixing ratio (g/kg)
12 i * SNOWMR real Snow mixing ratio (g/kg)
13 g * GRPMR real Graupel mixing ratio (g/kg)
Format( i4,i6,f6.1,i4,f5.1,f6.2,i3,f5.2,5f6.3)
MM5 Note: WD and WS are MM5 output at dot points,
other variables are interpolated in CALMM5 to dot
points from MM5 output at cross points.
w
Variable present in the record only if IOUTW = 1
q
Variable present in the record only if IOUTQ = 1
c
Variable present in the record only if IOUTC = 1 (possible only if IOUTQ=1)
I
Variable present in the record only if IOUTI = 1 (possible only if IOUTQ = IOUTC = 1)
g
Variable present in the record only if IOUTG = 1 (possible only if IOUTQ = IOUTC = IOUTI=1)
* Output for variables 9 – 13 will be compressed using a negative number if ALL are zero. -5.0 represents all five variables
are zero.
