MM5 V3 Utility Programs

The page lists a few useful utility programs that are available to work with V3 MM5 data.


Program to read MM5 modeling system output.

A patch to run observational nudging past year end. Thanks to Kilian Hagemann (Climate Systems Analysis Group, University of Cape Town)

To install the patch:
    run "patch -p0 < obsnudgeyear.patch" in the directory which contains
    the "MM5" directory whose contents you want patched.

Then regenerate all MM5OBS_DOMAIN* files with a new datetime scheme:    instead of the vanilla dddhh Julian date with floating point hour
   TIMEOB scheme that's given in section 8.7.4 of the manual you
   must now specify your observation's datetime as a YYYYdddhhf
   INTEGER (e.g. 2004005237) where:

     YYYY - 4 digit year (2004)
     ddd - 3 digit Julian day (005)
     hh - 2 digit hour (23h)
     f - 1 digit fractional part of the hour (.7)

     With the exception of the year all fields must be exactly as wide
     as specified above so that f becomes compulsory.

Alpine MM5 code

This code, supplied by G. Zängl (University of Munich), is based on version 3.6 of the standard MM5 released code. Special features included in this code are:
   (i) A generalization of the vertical coordinate that makes the coordinate surfaces nearly horizontal at some level below the model top, allowing better upperair structures, and
   (ii) An improvement to the upper radiative boundary condition for
use in nests.


Program to calculate some statistics (Thanks to Gerarado Cisneros, from SGI)

Program to Split Large MM5 modeling system output files into smaller files.


Program to convert MM5 V3 pressure level output (MMOUTP_DOMAINx) to GRIB format (Thanks to Alfons Callado i Pallarès of Instituto Nacional de Meteorología of Spain (Servicio de Modelización Numérica del Tiempo))

Program to convert MM5 model output to Vis5D format.

Program to plot time series of surface temperature, dew-point temperature, surface pressure, surface precipitation, surface winds and integrated cloud water from MM5 model (option IFTSOUT = 1 in V3.4 and higher).

Program to plot surface time series of sensible and latent heat fluxes, and ground temperature from MM5 model (option IFTSOUT = 1 in V3.4 and higher).

Viewing MM5 output using GrADS. (Thanks to George Bryan of Penn State.) 

Converting 32-bit IEEE data to 64-bit IEEE data, and more.
(Thanks to Wesley Jones of SGI.)

Converting MM5 V3 and V2 data to netCDF format.
(Thanks to Graziano Giuliani of University of L'Aquila, Italy.)  (Updated 02/12/03)
(Include hints from Ragharendra S Mupparthy and Rick Toracinta)

Program to paste multiple MMOUT files into one file.
This program will strip off additional big headers. This will result in smaller files, than when the 'cat' command is used.
(Thanks to Graziano Giuliani of University of L'Aquila, Italy.)  (Updated 02/12/03)

Program to convert MM5 V2 modeling system data from Regrid, Rawins/Little_r, Interp and MM5 to MM5 V3 format.

Program to convert MM5 V3 model data to MM5 V2 format.

 

A program to convert MM5 V3 model input data (MMINPUT, BDYOUT, and LOWBDY) to MM5 V2 format can be downloaded here.
