In my digging I discovered that the Apache webserver had open directory listings for folders, and this allowed me to explore a bit to see what I could find. in the \images folder I found a few images that I did not see published on the AIRS website. I’ve saved them to my server should they go offline, but have provided links to the original source URL.
One for Sea Surface Temperature at the tropics seems interesting, though the data period is too short to be meaningful. Note that to eliminate cloud issues, the soundings are done when the satellite has a lookdown to “clear sky”.
I find it interesting that there is a slight global cooling of the oceans during this period of September 2002 to August 2004. The question is: where is the rest of the data and why has the AIRS group not been presenting it on their website? It is after all a publicly funded NASA program.
It is also interesting that this goes against one of the “signatures” of an AGW driven warming. Dr. David Evans writes in this essay:
“The signature of an increased greenhouse effect is a hotspot about 10 km up in the atmosphere over the tropics.”
“The signature of an increase in well-mixed greenhouse gases (such as due to carbon emissions). Warming would be concentrated in a distinct “hot spot” about 8 – 12 km up over the tropics, less warming further away, turning to cooling above 18 km.”
What I’d REALLY like to see is the January version of this map:
Unfortunately, the January version of this image is unavailable. It would be interesting to see if the concentrations in the northern hemisphere maintain which would point to industrialization sources. Or, if the pattern flips, and we see concentrations decrease in the NH and increase in the SH, that would point to seasonal variation and thus likely be driven by biomass.
I’ve put in a request to the AIRS group for the January 2003 image, and others, we’ll see what happens.
UPDATE: 7/31/08 I got a response, see this new posting
