Quote:You didn't actually read the paper did you? Where did I say balloons have more coverage than satellites? The website you linked was described in the climate denier website (http://joannenova.com.au/2015/05/new-sat...-balloons/). This is what Dr. Roy Spencer said:

 

Roy Spencer has used new methods to improve the satellite signal of the hot spot, and is “increasingly convinced” the all important mysterious hot spot is really not there, which fits with 28 million weather balloons and humidity data too.  Satellites are not particularly good at finding the hot spot because it is a very thin layer over the tropics and satellites peering down from on high find it difficult to measure signals from 10km up and separate them from signals, say 8km up. Radiosondes are much better at resolving the different layers, which is really what matters — only the uppermost layer of water vapor counts, not the total column. Having said that, satellites are pretty handy over the oceans where not many weather balloons get released, and it would be good if we could use them.
