 disdroDLv2 is a Python software for acquiring and storing data from the OTT Parsivel2 optical disdrometer, developed by TU Delft, within the framework of the Ruisdael observatory for atmospheric science. 
 
 The software features a main script ([main.py](./main.py)) for setting up a serial connection with the Parsivel, requesting data at regular time intervals, and storing the output in a NetCDF file.
