We have included three example runs during the initial DLSM set up into your input directories: 

exampleCoherentSS: a coherent DWL- single shot conically scanned simulation. Warning: single shot simulations can take a long time to run and can create very large (gbyte size) output files. This example is a 1 hour simulation and it creates a 457 Mb output los file.

exampleCoherentAcm: a coherent DWL - accumulation step-stare simulation.

exampleDirectAcm: a molecular direct detection DWL - accumulation step stare simulation. 

It is recommended that the user enter the inputs for themselves and run the models to produce the sample output files for comparison. A performance graphic of the Doppler Wind Lidar Data Quality Profile Observation Uncertainty: HLOS with clouds should be created and compared with the graphic on the Examples page to insure that the results are the same.
