Pétron, G., Granier, C., Khattatov, B., Yudin, V., Lamarque, J., Emmons, L., Gille, J. and Edwards, D.P. (2004). Monthly CO surface sources inventory based on the 2000–2001 MOPITT satellite data. Geophysical Research Letters 31: doi: 10.1029/2004GL020560. issn: 0094-8276.

This paper presents results of the inverse modeling of carbon monoxide surface sources on a monthly and regional basis using the MOPITT (Measurement Of the Pollution In The Troposphere) CO retrievals. The targeted time period is from April 2000 to March 2001. A sequential and time-dependent inversion scheme is implemented to correct an a priori set of monthly mean CO sources. The a posteriori estimates for the total anthropogenic (fossil fuel + biofuel + biomass burning) surface sources of CO in TgCO/yr are 509 in Asia, 267 in Africa, 140 in North America, 90 in Europe and 84 in Central and South America. Inverting on a monthly scale allows one to assess a corrected seasonality specific to each source type and each region. Forward CTM simulations with the a posteriori emissions show a substantial improvement of the agreement between modeled CO and independent in situ observations.
