Python environment for stand-alone tool

/gws/nopw/j04/dcmex/users/hburns/DCMEX2/DCMEX2.yml

to install this please use

conda env create -f /gws/nopw/j04/dcmex/users/hburns/DCMEX2/DCMEX2.yml

Using the tool

1. Activate the python environment conda activate cloud_heights
2. run the python script e.g. python /gws/nopw/j04/dcmex/users/hburns/DCMEX2/cloud_height_standalone.py --file /gws/nopw/j04/dcmex/users/hburns/DCMEX2/images/20220730/pass_276_ffc/frame_c307_20220730_165926_sky_bluesky_ffc.png --px 575 --py 300 --D 6000

• this uses absolute paths but will work with relative paths as well or
  • export DCMEX2pth=/gws/nopw/j04/dcmex/users/hburns/DCMEX2/
  • export cldimgpth=/gws/nopw/j04/dcmex/users/hburns/DCMEX2/cloud_heights/images
  • and run python $DCMEX2pth/cloud_height_standalone.py --file $cldimgpth/20220730/pass_276_ffc/frame_c307_20220730_165926_sky_bluesky_ffc.png --px 380 --py 300 --D 5000

tool arguments:

• -h help prints the help string similar to this
• --file (required) relative or absolute path to file
• --px (optional) pixel x co-ordinate override. Default mid point originating autosearch for cloud edge
• --py (optional) pixel y co-ordinate override. Default - autodetected cloud edge
• --D (optional) Distance override. Default - mid point of pass

Outputs

• prints to screen variables used and heights calculated
• prints to csv all variables used in calculations including aircraft data (current working directory or home dir if no permission in cwd)
• saves a png of new annotated figure (you must rename to prevent overwriting with different pixel point) (current working directory or home dir if no permission in cwd)
