concat_pollyxt_files.py provides a routine for combining the attenuated backscatter at 1064 nm and the calibrated volume depolarization at 532 nm from the Pollynet_Processing_Chain into one daily file.

Usage

The python script now can be used with arg-parsing as follows:

python3 concat_pollyxt_files.py --help

usage: concat_pollyxt_files.py [-h] [-t timestamp] [-l location] [-i input_path] [-o output_path]

Concatenate pollyxt nc-files (att_backscattering@1064nm and vol_depol@532nm) from one day, with input variables: timestamp, location, input_path, output_path

optional arguments:
  -h, --help            show this help message and exit
  -t timestamp, --timestamp timestamp
                        input the timestamp of pollyxt measurement
  -l location, --location location
                        input the location/site of pollyxt measurement
  -i input_path, --input_path input_path
                        set the absolute input path to the polly dataset; if not set, the script tries to find the correct dataset from timestamp and location input
  -o output_path, --output_path output_path
                        set the absolute output path for the resulting, concatenated nc-file

If no input_path is set, this script tries to locate the correct dataset. This is only working for the location 'Mindelo' at the moment and if working on the TROPOS-server.

Here is an example:

python3 concat_pollyxt_files.py -t '20210912' -l 'Mindelo' -i '.' -o '.'

Output format

An example for the current output format is provided in output_format.txt
