Configuration

The LorenzCycleToolkit requires specific configuration files for both fixed and moving frameworks. Below are examples and descriptions of the required configuration files.

Namelist File

The namelist file specifies the variable names and units used in the input NetCDF file. Here is an example namelist file for the NCEP-R2 dataset:

;standard_name;Variable;Units
Air Temperature;air_temperature;TMP_2_ISBL;K
Geopotential Height;geopotential_height;HGT_2_ISBL;m
Omega Velocity;omega;V_VEL_2_ISBL;Pa/s
Eastward Wind Component;eastward_wind;U_GRD_2_ISBL;m/s
Northward Wind Component;northward_wind;V_GRD_2_ISBL;m/s
Longitude;;lon_2
Latitude;;lat_2
Time;;initial_time0_hours
Vertical Level;;lv_ISBL3

Box Limits File (Optional)

The box_limits file defines the spatial domain for the fixed framework. It is a CSV file with the following format:

min_lon;-60
max_lon;-30
min_lat;-42.5
max_lat;-17.5

Track File (Optional)

For the moving framework, a track_file can be used to define the system’s center over time. Optionally, length and width columns can be added to adjust the domain size. Here is an example track_file:

time, lon, lat, length, width
2021-01-01 00:00:00, -50, 0, 10, 10
2021-01-01 06:00:00, -49, 1, 10, 10
2021-01-01 12:00:00, -48, 2, 10, 10
