Hi @pereza - Thanks for sharing this exploration. Unfortunately, it’s true that there are many samples with missing satellite data. That’s just the reality of satellite orbits that this data is derived from. It’s part of what makes this challenge, well, a challenge! Here’s another thread where this is discussed: Strategy to impute missing data? - #2 by Carl_Malings
I would also suggest exploring how ancillary and historical data could help fill in the gaps. Good luck!
