The a posteriori global monthly mean isoprene emissions by Shim et al. [2005] are shown in the figure. The spatial resolution is 4x5. The longitude centers are sequentially 177.5 W, 172.5 W, ..., 177.5 E. The latitude centers are sequentially 89 S, 86 S, 82 S, ...,82 N, 86 N,  89 N. The unit is Tg C per grid box. Grid box areas are given for appropriate flux unit conversion. The monthly mean a posteriori emissions are available for January, February, March, April, May, June, July, August, September, October, November, and December.
