### Input data requirements
### Input data requirements
The model (as per 2023-10-25) assumes that weather data files named `met_1_0km_nordic-[YYYY-MM-DD].nc` are available in the `in/` folder. The files must contain hourly timesteps with the following weather parameters:
The model reads weather data files from this path: `[WEATHER_DATA_DIR]/[FILENAME_PATTERN]` . The variables are shell environment variables, see below. The files must contain hourly timesteps with the following weather parameters:
