I built it so I could learn how to make Google Map Tiles out of CF netCDF files with Ferret and to see if I could run a "production" site on GCP. It worked out ok. Since it cost me real money (about $80/month) to process the NOAA HRRR data files (re-grid them to rectalinear from the native curvilinear grid, and convert them to netCDF) I shut down the site. I have some ideas for other things to try to build with the Ferret tile maker and interactive maps.
