CMIP6 data vs Observed Data

Hello,
Currently working on SWAT streamflow modeling and climate projection using CMIP6 data. I want to know how I can get the grid coordinates from the CMIP6 model to match that of the observed data (specifically NOAA). Is there any way to know the grid coordinates of the CMIP6 data?

Yes. Which CMIP6 data are you working with?
