    1010- A binary file from DustMonitor (GRIMMs software)
    1111
    12 The DustMonitor files comes in .dm and .di pairs (measurements and metadata respectively)
     12The DustMonitor files comes in .dm and .di pairs (measurements and metadata respectively). There should also be a _nav file.
    1313
    1414The software can run in two modes - particle count or mean mass.
     
    4040The GRIMM output from the spectrometer has a timestamp but no positional information.  knpa has written a script to use the timestamps to append position info from the ARSF navigation files: ~arsf/usr/opt/grimm/add_position_2_dustMon_output.py
    4141
     42Usage:
     43add_position_2_dustMon_output.py <comma_sep_grimm> <grimm_nav_file> <sol_file>
     44
     45The grimm_nav_file is the nav file that is automatically output by DustMonitor in-flight. The sol_file is the ARSF post-processed nav file. The latter is used first, with the grimm nav file only being used when the sol file lacks coverage (which often occurs at the start or end).

    4449knpa has also written a script to identify periods where the plane is ascending or descending so as to extract vertical profiles: /users/rsg/arsf/usr/opt/grimm/grimm_extract_vertical_profiles.py
    4550
     51Usage:
     52grimm_extract_vertical_profiles.py <grimm_file> [-p]
     53
     54Extracts vertical profiles with stats describing the min/max values. -p argument to print rather than write to a file.
