Hey guys, how's it going? We're hitting an issue with saving cubes that have masked cell measures attached to the main variable, see ESMValGroup/ESMValCore#1917 - I don't really understand the issue with this, so long as one supplies the saver with a valid fill_value (like we do, the infamous 1e20) - is this something that's a bit legacy or you're still afraid of it? Cheers muchly 🍺
