GISS (Goddard Institute of Space Studies) Surface Temperature Analysis (GISSTemp) released their monthly global temperature anomaly data for August 2008. Following is the monthly global ∆T from January to August 2008
Year J F M A M J J A
2007 85 61 59 64 55 53 53 56
2008 14 25 60 42 40 28 50 39
Here is a plot of the GISSTemp monthly anomaly since January 1979 (keeping in line with the time period displayed for UAH). I have added a simple 12-month moving average displayed in red.
Where can you find the actual average temps used for the different baselines ?
i.e. I know the year ranges. What about the actual values ?
Just have a question. I hope it’s not too ignorant, trying to get my mind around ththe different temp data.
I was reading above about cooling in the troposphere data compared with surface data. If the surface data is getting warmer then wouldn’t the troposphere be cooling faster ? i.e. a hotter cup of water will cool faster than a not so hot cup of water.
Wouldn’t that cause a divergence in temperatures readings between a higher altidtude and the surface ?
Is the UAH data supposed to calculate supposed temperatures at the surface ? Or is it more concerned with the trend and changes in anomalies ?
If the lower tropo data is supposed to reflect surface temps and people seem critical of surface temps because they are higher. Why is the mid tropo data not the same as the lower tropo once the anaomalies have been calculated ?
For a naive novice, the first assumption was that obviously surface temperatures are higher, they are lower, it’s much colder as you get higher. The fact that the mid tropo graph was lower still than the lower tropo seemed to support this. So what are the actual facts ? [thanks :)]
