Hi Sander,
I was wondering how you would recommend creating a moving 10 day average to create an animation highlighting emission levels over a. certain period? (like this: [https://www.youtube.com/watch?v=ARpxtAKsORw](https://www.youtube.com/watch?v=ARpxtAKsORw)) I could do it by using by merging my daily files as so: Jan 1 - Jan 10, Jan 2 - Jan 11 etc but I feel this would be cumbersome and inefficient. Is there a better way to do this maybe somehow incorporate time values into my monthly averages?

The merge approach you describe is how you would do it. You would just merge the daily files of 10 days into a single merged average. Each day you would create one new 10-day averaged grid based on the grid of the current day and those of the last 9 days. I don’t see anything inefficient in that.
