'splain' My Detrending
There are a lot of sophisticated methods to manipulate time series to determine trends and remove trends for data series. I ain't all that sophisticated, some I am starting with baby steps. As the oceans temperature changes, the sea level should change somewhat. There are other factors involved in sea level change, but I wanted to see how well the UAH atmopsheric temperature data followed the sea level changes recorded by satellite altimetry. I downloaded the data for the NCDC site
, but right now I can't find the exact link. Anywho, there is a much higher slope in the sea level change than in the mid troposphere temperature over the oceans as determined by the UAH MSU data. To better compare, I removed the slope in the seal level data, or simple removed the greater trend.
