The spatial distribution for a-priori and a-posteriori \(\:\text{N}{\text{H}}_{4}^{+}\), \(\:\text{S}{\text{O}}_{4}^{2-}\), and \(\:\text{N}{\text{O}}_{3}^{-}\) concentrations constrained by different satellites for May. Spatial distribution of a-priori and a-posteriori concentrations of \(\:\mathbf{N}{\mathbf{H}}_{4}^{+}\) (left column), \(\:\mathbf{S}{\mathbf{O}}_{4}^{2-}\) (middle column), and \(\:\mathbf{N}{\mathbf{O}}_{3}^{-}\) (right column) constrained by different satellites for May 2019. The first row also presents prior concentrations, the second row shows posterior concentrations constrained by IASI, the third row by CrIS, and the fourth row by the combined IASI/CrIS. The calculations, as well as the maps, were produced with a Python (3.9.5) script (https://www.python.org/downloads/release/python-395/).
