"How well do ground measurements do with the troposphere?? It is sort of important to measure thatt to!."

Why? How many people live there? But, I digress; weather balloons are more accurate than satellites.

Uh, I haven't made that claim at all. There are atmospheric scientists who are idiots, and some who aren't. But anything communicated through a third party who is ignorant of the topic is suspect.

As to measurements, it really depends on what you're using them for. You can't make a blanket statement that one is better than the other. Even though historically, tree ring data is terribly inconsistent, it provides information for those years where it IS available that is of excellent quality. It just isn't very useful for statistical purposes sometimes.

You probably cannot make broad statements about most data sources.
