The data set comprises CH4 (methane) data of the Earth's uppere troposphere and middle atmosphere region for the years 2002-2012 as derived from MIPAS on Envisat and retrieved with the IMK/IAA level-2 processor. The MIPAS observation modes FR (2002 - 2004, CH4_61), RR-NOM (2005 - 2012, CH4_261), RR-UTLS-1 (2005 - 2007, CH4_161), RR-MA (2005 - 2012, CH4_561 & CH4_562), and RR-UA (2005-2012, CH4_662) are covered. Data versions CH4_161, CH4_261, and CH4_561 are compatible and could be used together. The same holds for data versions CH4_562 and CH4_662. The data is based on version V8 infrared spectra.
