A few thoughts from a geographer (be prepared to shoot me):

- Basically every comment is wowed by this, but nobody questions what the accuracy is. I, too, can Krig interpolated surfaces to any resolution.

- off-nadir view doesn't seem to offer much

- We've been dealing with janky tile loading for like 20 years now. I really hope we'll get a much smoother approach for viewing these tiles as they load. The dissolve transition hides it a bit, but makes the data uncomfortable to view when playing the timeseries.

- I'm deeply curious about the Picnic data layer. Can someone share the ArcGIS/QGIS model for that one? =D

Thanks for chiming in. I can make an animation say whatever I want. I am very curious about the accuracy.

Unrelated: The site breaks my back button in Chrome, which is an unforgivable UI sin.

This seems to be a thing with weather models more generally. Somewhat relatedly, I've spent quite a bit of time evaluating weather models for use in India and Africa, and while predictions are easy to find, validation results for the predictions are very hard to find. And when you do find them, the results are pretty poor, with many models performing worse than if you would say "predict temperature on date X to be the average observed temperature on the same date in the past 10 years". But people still sell (and buy) these predictions!

Weather predictions seem to be accepted quite uncritically. Perhaps people have a lot of confidence in the smart people that built these predictions (a bit like how AI predictions can sometimes be accepted uncritically).

I had been wondering if that was actually something special because I thought I remembered that the German Meteorological Service ("Deutscher Wetterdienst") offered accurate forecasts on a sub-kilometer grid for years already. At least if you are ready to spend money on that because that service is not free, so maybe that's the innovation here.
