Time Series Output

  • Create a output of surface values (see below) at EACH model time step.
  • Output are written to files called fort.25, fort.26, etc. fort.25 contain the time series information for points in domain1, fort.26 contain information for domain2, etc.
  • The fort.2? files are ASCII files.
  • The output is only surface values. Below is the full output list.
     
    • forecast time in minutes (xtime)
    • Nth time series (time-step)
    • J and I locations of the time series (its & jts)
    • 2-m or lowest σ level temperature in Kelvin (t-sfc)
    • 2-m or lowest σ level mixing ratio (kg/kg) (q-sfc)
    • 10-m or lowest-σ level winds (m/sec), rotated to earth coordinates (u-sfc, v-sfc)
    • reference p* (unit cb, or 10*hPa) (pstar)
    • perturbation pressure at the lowest-σ level (unit Pa) (pp-sfc)
    • accumulative convective precipitation (cm) (rainc)
    • non-convective precipitation (cm) (rainnc)
    • column-integrated cloud water (mm) (clw)
    • surface downward long-wave and short-wave radiation (W/m^2) (glw, gsw)
    • surface sensible and latent heat (latent heat of vaporization) flux (W/m^2) (hfx, qfx)
    • ground or skin temperature (if ISOIL = 2) temperature in Kelvin (t-ground)

If running MM5 MPP, the output will be in available in the rsl.out.**** files, i.e., no fort.2? files will be created.

If the lon/lat point you are creating a time series for, falls in the area where processor 2 are performing the calculations, the time series will be written out to rsl.out.0002 (see X in example below - where the boxes 0-3 indicate the processor number performing the calculations over that area of the model domain).

configure.user

No different settings are required here


mm5.deck

TISTEP = 240., ; coarse domain DT in model, use 3*DX
IFTSOUT = .TRUE., ; output time series (default 30 points)
   TSLAT = 40.0,48.0,0.0,0.0,0.0, ; latitudes of time series points (S is negative)
   TSLON = -100.0,-110.0,0.0,0.0,0.0, ; longitudes of time series points (W is negative)

  • A time series for 2 points (40N;100W & 48N;110W) will be created
  • Data will be written out every 240sec.

The data will be written to the CLOSEST I/J point.

NO interpolation to the exact location will take place.

 

Two user contributes utility plot programs are available to plot the data generated with the IFTSOUT option

  • Program to plot time series of surface temperature, dew-point temperature, surface pressure, surface precipitation, surface winds and integrated cloud water from MM5 model
  • Program to plot surface time series of sensible and latent heat fluxes, and ground temperature from MM5 model
 

Alternatively, one can generate time series output from any MM output file with a utility.
