We have come to the end of another full cycle of IASI 600 mb methane release tracking, and Dr Yurganov's June 30 chart reveals the full changes of 2012-2013 vs what was detected by the METOP A IASI satellite in prior years. The Barents, Kara, Norwegian Sea outburst of methane in January to April 2013 was a record, and it will be interesting to see if it repeats in 2013-2014.
Also, a new website tracking the METOP 2 IASI imagery on a global basis has just been announced, http://methanetracker.org is a powerful tool that will revolutionise how we track methane release in near real time globally,

There are several changes to the website. First , the AIRS/AQUA/Giovanni CH4 data is no longer being generated by NASA as of February 28, 2013. Thus the AIRS CH4 359 hPa imagery is no longer being updated. However, Dr. Yurganov's IASI 600 mb imagery is still being created and displayed at the IASI tab above. The IASI tab is still being updated. The changes in CH4 concentration comparison in the Barents and Norwegian Seas has been updated and shows a drop back towards prior year's emissions over the last few months.
However, it is possible that as the water warms over the next few months, both seas will increase emissions again.
The Laptev, Kara and ESS do not have the same major jump in emissions through last winter, however, as the ice fractured in March through May, there were slight increases in CH4 concentration at 600 mb. That has declined as the atmosphere has warmed as summer approaches.
I am in the process of updating the daily IASI 2 CH4 images. However, there is a new tool under development which will significantly enhance methane monitoring globally. More on that in the next few weeks. It will radically change how CH4 release and concentration is understood.
March 11-20, 2013
The AIRS/AQUA/Giovanni images reveal an increased concentraion of CH4 over the CAB, in some areas over 1900 PPBv. The pattern is different than 2012, perhaps due to the shift in the Arcitc high pressures.
The second 10 days of March reveals ongoing record level concentrations of CH4 in the Norwegian and Barents Seas, with increasing concentrations in the Laptev, ESS and Okhotsk as the ice fractures and CH4 accumulations in the ice are released into the atmosphere.
Dr. Yurganov's comparison of 600 mb reading reveals continued record high methane concentrations in the Barents and Norwegian Seas.
Dr. Yurganov's readings for CH4 in the Laptev and East Siberian Seas at 600 mb compared to 2012 reflect the fracturing as a potential release factor for methane.
March 1-10, 2013
Dr. Yurganov has been comparing the CH4 levels in the Barents and Norwegian seas at 600 mb. The graph below reflects this season's methane levels compared to prior years. The March 1-10 2103 is the highest recorded in the Barents and Norwegian Seas.
January 21-31, 2013
During January 21-31, 2013, the Norwegian, Barents and Kara Seas had the highest CH4 readings at 600 mb. They are at a "record high," according to Dr. Yurganov. The AIRS/Aqua imagery reflects a significant drop in CH4 concentration compared to prior years, at 359 mb.
