No data starting at... in M3TPROC

I/O API m3tools

I have an emissions file that has 25 time steps (2016001:080000 → 2016002:080000). I’m trying to generate a file with a daily total (24 hours). When I run M3TPROC I get the following errors.

Enter final time for analysis

means to enter starting time for the last (24-hour) time step that will be processed. You should have taken the default 2016001 instead of entering 2016002.

The file goes from 8 on one day to 8 on the next day though. When I use the same date for the final day it gives me the same error.

Upon looking at things more carefully: this is a bug (note the “0 input time steps”).

Quick fix: add the following "ASTEPS =..." as a new line 400 in the m3tproc.f90 source code (after the “NRECS =...”, as shown below:

    ...
    NRECS  = CURREC( EDATE, ETIME, SDATE, STIME, OSTEP, KDATE, KTIME )
    ASTEPS = TIME2SEC( AGLEN ) / TIME2SEC( INSTEP )
    ...

Fixes to the repository will be forthcoming soon.

Awesome! Thanks for the quick fix!
