Erm,I know what I'm talking about.
Maybe, but when you spout nonsense like:
The measure certain stuff using other satellites radiation/emissions etc.
Why are we supposed to believe you. The NOAA MSA and AMSU instruments measure microwave emissions from oxygen, they do not use "other satellites radiation/emissions etc".
Then you continue with:
How exactly is a clock that measures how a satellite radio signal is slowed down through the atmosphere depending on moisture and temperature 'degrading'
The NOAA satellites don't have "a clock that measures how a satellite radio signal is slowed down through the atmosphere depending on moisture and temperature"
Then you bring up GPS:
The GPS satellites don't 'degrade' but the satellites measuring their signals, do?
Then you make the unsupported assertion:
neither are those instruments nor measurements degrading nor are they perfect.
We know the instruments are not perfect, look at the problems with the "hot target" for example.
As for not degrading, you might like to check out the NOAA status page.
12/16/2008 00:00:00 MetOp-2 AMSU-A1 Channel 7 degradation began violating specifications beginning 12/16.2008.
Conclusion: You don't know what the fuck you're talking about.
