Global CH4 flux inversion 2000-2012 (MACC / NOAA only)

Inverse modelling of global CH4 emissions during 2000-2012 based on TM5-4DVAR model and NOAA surface observations (described in detail in Bergamaschi, P., S. Houweling, A. Segers, M. Krol, C. Frankenberg, R. A. Scheepmaker, E. Dlugokencky, S. C. Wofsy, E. A. Kort, C. Sweeney, T. Schuck,C. Brenninkmeijer, H. Chen, V. Beck, and C. Gerbig (2013), Atmospheric CH4 in the first decade of the 21st century: Inverse modeling analysis using SCIAMACHY satellite retrievals and NOAA surface measurements, J. Geophys. Res. Atmos., 118, 7350–7369, doi:10.1002/jgrd.50480). The data set includes gridded monthly average fluxes and daily average 3D CH4 concentration fields基于TM5-4DVAR模型与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）地面观测资料的2000—2012年全球甲烷（CH4）排放反演建模研究，详细研究内容参见Bergamaschi, P.、S.
