| 1 """ Sample script to convert licel files to SCC netcdf format. | |
| 2 | |
| 3 The script assumes the following things: | |
| 4 | |
| 5 1. You have already installed the atmospheric_lidar module (e.g. using pip). | |
| 6 2. You have create a class in a file "lilas" describing your system (described the readme file). | |
| 7 If you want to use it for a different system you need to change the script to use your own class | |
| 8 | |
| 9 Run the script using: python convert_lilas.py <your options> | |
| 10 | |
| 11 Examples | |
| 12 -------- | |
| 13 # This will read all files starting with "l" from "my_dir". | |
| 14 # It will guess the measurement ID based on the date of the files, and will assume measurement number 00. | |
| 15 # For example, the new measurment id could be 20120101mb00 | |
| 16 python convert_lilas.py my_dir l*. | |
| 17 | |
| 18 # This will use the measurement id you defined. | |
| 19 python convert_lilas.py my_dir l*. -m 20120204mb32 # It will create the file 20120204mb32.nc | |
| 20 | |
| 21 Help string | |
| 22 ----------- | |
| 23 # To get this, run: python convert_lilas.py -h | |
| 24 usage: convert_lilas.py [-h] [-m MEASUREMENT_ID] [-n MEASUREMENT_NUMBER] | |
| 25 [directory] [searchstring] | |
| 26 | |
| 27 positional arguments: | |
| 28 directory Directory with licel files. | |
| 29 searchstring Processing system id. | |
| 30 | |
| 31 optional arguments: | |
| 32 -h, --help show this help message and exit | |
| 33 -m MEASUREMENT_ID, --measurement_id MEASUREMENT_ID | |
| 34 The new measurement id | |
| 35 -n MEASUREMENT_NUMBER, --measurement_number MEASUREMENT_NUMBER | |
| 36 The measurement number for the date, if no id is | |
| 37 provided | |
