@KORINA Why not? We all know it's not on your road map - so no need to tell us that again... We want you to put it on your road map. Then, we want you to use your road map to tell us when it will arrive. And of course, the necessary formula to create a new "wind chill" layer is simple and uses the data we can already toggle for display. OR..... Since it's such a simple implementation, perhaps the most obvious explanation is that you have decided not to provide this. In which case, the way to keep the support of those users who would like it would be to explain why you will not put it on your road map
