Spatiotemporal discrepancies between satellite- and inventory-derived estimates of global ammonia emissions

Bottom-up inventories and satellite-constrained estimates of ammonia emissions often diverge, but the conditions driving these discrepancies remain unclear. Here we compare monthly global estimates at 0.1° resolution from 2008 to 2016 using a normalised discrepancy index. Satellite-constrained emissions are higher on a...
