atm_dist

This application calculates the transport deviations of trajectories.

atm_dist can be called by:

# calling atm_dist
$ ./atm_dist  <ctl> <dist.tab> <param> <atm1a> <atm1b> [<atm2a> <atm2b> ...]

The required arguments to run atm_dist are as follows: * ctl: is the control (.ctl) file of the trajectory simulation
dist.tab: the output file where the deviations should be written into
 param: the deviation parameters to be calculated, for example absdev. * atm1a and atm1b: the trajectory files that should be compared

Statistical parameters that can be calculated are:

  • mean
  • stddev
  • min
  • max
  • skew
  • kurt
  • absdev
  • median
  • mad

The statistics are calculated with the GNU Scientific Library. More information on the GNU Scientific Library statistics functions can be found on their webpage.

An example command line for running atm_dist looks like as follows:

./atm_dist trac.ctl dist_absdev.tab absdev traj_sim1_2017_01_01_00.tab traj_sim2_2017_01_01_00.tab

Note: The command line needs to be adjusted to the respective directories were the files (or executables in case of atm_dist) are located.

Additional parameters that can be used when running atm_dist are:

DIST_LAT0 -89 DIST_LAT1 89 - The latitude range to be considered
DIST_Z0 8 DIST_Z1 16 - The altitude range to be considered
DIST_ZSCORE - can be used for filtering outliers
