`m3tools` Program `M3MXFIND`

Usage

    setenv  IN_FILE     <path name>
    setenv  IN_VBLE     <${IN_FILE} variable name>
    setenv  AGGSTEP     <analysis-period HHMMSS> [240000]
    setenv  OUTFILE     <path name>
    setenv  SDATE       <starting date for analysis [SDATE3D from file]>
    setenv  STIME       <starting time for analysis [STIME3D from file]>
    setenv  EDATE       <ending date for analysis [from file]>
    setenv  ETIME       <ending time for analysis [from file]>
    
    m3mxfind

where IN_FILE, OUTFILE are the logical names of the input and output files, IN_VBLE is the name of the variable for the MAX-analysis, and AGGSTEP is the length of the analysis window.

Summary

Program M3MXFIND finds the date-and-time maximum value for a selected variable IN_VBLE from a time stepped gridded input file IN_FILE, over the specified (sliding, time stepped) analysis-window, and writs the result to an ASCII output file listing the analysis-window date&time ADATE:ATIMEand the date&time MDATE:MTIME for the maximum of that variable within that slided analysis window. For example, if the input file starts at 2016001, has a one-hour time step, and duration 7 days, and the analysis window has default duration 24 hours, and the anaalysis is for ozone O3a sample output might look like the following:

    2016001, 000000, 2016001, 170000
    2016002, 000000, 2016002, 140000
    2016003, 000000, 2016003, 120000
    2016004, 000000, 2016004, 140000 
    2016005, 000000, 2016005, 130000 
    2016006, 000000, 2016006, 130000 
    2016007, 000000, 2016007, 150000

where, for example, this says that the maximum ozone for day 2016005 happened at date-and-time 2016005:130000.
