I am working on a project based in Alaska, and put together a script using the API to see how many image-days per month are available in my study region.  However, I noticed a really weird trend in 2022 and beyond, where the average daily images drops by almost 50%.  What is going on here?  I have attached a graph showing data availability with a Planet cloud threshold of 25% image cloud cover (ignore the grey trend line behind, that is unrelated to planet data.)

What is going on here with the drop in data coverage?
