Description
This dataset provides a simulated data stream representative of an Atmospheric Tomography mission (ATom) data collection flight and also modeled reactivities for ozone (O3) production and loss and methane (CH4) loss from six global atmospheric chemistry models: CAM, GEOS-Chem, GFDL, GISS-E2.1, GMI, and UCI. The simulated data include concentrations of selected atmospheric trace gases for 14,880 air parcels along a simulated north-south ATom flight path along 180-degrees longitude over the Pacific basin. Each of the six models produced ozone production and loss and methane loss reactivities initialized using the simulated data beginning with five different days in August (8-01, 8-06, 8-11, 8-16, 8-21). Modeled years for each individual model varied from 1997 to 2016.

Each point is an average over the 5 simulated dates in August (8/01, 8/06, 8/11, 8/16, 8/21). The 1:1 line is shown (black dashed) for each plot. The reference values (X axis) are the average of 3 similar models (GSFC, GC, UCI) selected by examining the rms differences across all the models (see text). Note that the model points are plotted successively on top of one another and thus the earlier-plotted models may appear less frequent: in order, NCAR (black), GFDL (magenta), GISS (cyan), GC (blue), UCI (red), GSFC (green).
