I used to work for a company that manufactured and installed flight information systems at airports. I observed the relocation of those sensor housings from proper locations to hot zones at several airports. My colleagues observed the same thing at additional airports.

This occurred in the 1989-1991 time frame.

I seem to recall reading that the Clinton era FAA ordered sensors moved closer to runways in order that pilots receive "more accurate" information about runway conditions.

A long time ago, I read an article stating that global temperature and weather models had for many years included data from weather stations scattered across the USSR. Afer the Soviet Union collapsed in 1991 many of those stations were abandoned and left to fall into ruin and that data stopped being included. What I remember most about the article was one scientist's analogy that said it would be like charting global per capita income and then all of a sudden, stop including data from sub-saharan African. Unsurprisingly, you would see a, "hockey stick," rise in the per capita numbers, and such was the effect of the sudden cessation of data from the former USSR on global temperatures.
