 The scripts provided here wrap around the code related to `CTSM/tools/site_and_regional/subset_data` for single point data creation, available in [the CTSM repository](https://github.com/ESCOMP/CTSM/tree/ctsm5.1.dev112/tools/site_and_regional). A tutorial is available [here](https://github.com/NCAR/CTSM-Tutorial-2022/blob/main/notebooks/Day2a_GenericSinglePoint.ipynb). Please ensure to attribute this work if you use this code.
