We plow the snow away from around the building. Unfortunately the building is up on a small rise but it does make it easy to get the snow line below the ground plane.

I don't recall any concerns, because the snow was not on top. - Bill At 01:06 PM 12/12/2001 , [email protected] wrote: Once upon a time, before we were spun off from IBM, and I was the EMC manager here, I faintly recall that the IBM Boebligen lab in Germany had an OATS facility. I also faintly recall that snow on the rooftop did impact the measurements needed. Note that OATS structures are normally constructed with non-conductive materials, e.g. wood, plastic, etc. A layer of snow represents a plane of conductive material, albeit not a great conductor. However, these are memories from the distant past. Surely there are some still using OATS facilities where winter snow is a problem.

How does snow accumulation on the roof affect performance measurements? Does it affect the NSA figures? Is the effect significant enough that attempts are made to keep the roof snow free? Or does the normal attempt at keeping the inside test area warm enough for people take care of snow build-up? ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
