# This script demonstrates running MCS tracking on model OLR + precipitation data
# To run this demo script:
# 1. Modify the dir_demo to a directory on your computer to download the sample data
# 2. Run the script: bash demo_mcs_model25km.sh
# 
# By default the demo config uses 4 processors for parallel processing, 
#    assuming most computers have at least 4 CPU cores. 
#    If your computer has more than 4 processors, you may modify 'nprocesses' 
#    in config_model25km_mcs_tbpf_example.yml to reduce the run time.
