. At what level do these temps potentially affect operation of the OBS? Is it possible to still go outside to clear ice and do the other normal duties in these conditions?
There hasn't been a wind chill that has affected operations here. The thing to keep in mind is those are wind chill values not actual ambient air temperatures. Wind chill only affects exposed skin so the key is to make sure there is nothing exposed by either having another person inspect you or using a mirror to inspect ourselves as I do at night. The thing is, we are so bundled up so that after 0, it all feels the same. And since wind chills do not affect instruments operations, we still have to deice. Temperatures have never affected operations. Winds and thunderstorms on the other hand...
