I am a new user, and I love this tool. However, I see a station reporting a temperature of -561C, a physical impossibility. I suggest filtering out impossible values. It would also be good, though computationally expensive, to filter out improbable values -- the algorithm that comes to mind is to compute the first derivative of the displayed variable with respect to position along an east-west axis (or north-south or both) and delete points that give rise to unbelievable slope values. But, as that takes a lot of CPU, it might be better to let a user press the value to open its data sheet and then toggle a switch to either remove it or report it to you for editorial attention.
