Thanks for pointing out the status of ERA5 on GCP and AWS.

I'll have to try the binning and compare it with listing all the values and finding the 99th percentile! But yeah the spatial part of that query might be the tougher part.

And yeah I also considered whether to use ERA5 or ERA5-Land. I don't remember if ERA5-Land was missing a variable or I just wanted to look at some ocean grid cells, but I decided to start with vanilla ERA5.
