AIRS 2012 vs 2011 CH4 359 hPa

2012 AIRS
 
The following imagery is the methane PPBv from the 2012 AIRS/Aqua data, 45-90N latitude, as a 10 day average at 359 hPa ascending, created using Giovanni. http://disc.sci.gsfc.nasa.gov/giovanni/overview/index.html
The methane mapped is that tracked in the middle troposphere at 26,045.1 feet or 7,938.6 meters.
 
Purple = LT 1800 PPBv
Greens = 1840-1870 PPBv
Yellows = 1870-1900 PPBv
Red = GT 1900 PPBv
