Question

what kind of cloud is this? (combo cloud)

Explanation:

The image shows a low - lying, uniform - looking cloud that covers a large area, reducing visibility (like fog but above the ground). Stratus clouds are low - level, gray, and cover the sky like a blanket. If it's a combo, maybe a stratus - based combo (e.g., stratus with some fog - like or other low - cloud features). But from the visual (even blurry), the dominant type here looks like stratus (or a stratus - fog combo, but stratus is the main low - level uniform cloud type here).

Answer:

Stratus (or a stratus - based combo cloud)
