Abstract

These GEOS-Chem simulations examine the effect of recent advances to our understanding of upper tropospheric chemistry on our ability to constrain lightning NOx emissions. These simulations examine the effect of the addition of methyl peroxy nitrate chemistry, as well as better constraints on the formation of pernitric acid, dinitrogen pentoxide, and nitric acid at the temperatures and pressures of the upper troposphere. These simulations include a base case, simulations implementing each change individually, all four together, and all four with a 33% increase in lightning NOx emissions. The outputs contained here are NO2 worldwide for all 2012, averaged at the overpass time of the Ozone Monitoring Instrument, and NO, NO2, HNO3, and O3 over North America during May and June 2012, averaged between 1600-2000 local time, coincident with the flight times of the Deep Convective Clouds and Chemistry field campaign.

Methods

This data was subset from the output of GEOS-Chem v9-02. Output was time averaged using the ND51 diagnostic series available in GEOS-Chem. Further subsetting and conversion from binary punch format to netCDF format was done in Matlab.

Usage Notes

The data are stored as compressed netCDF4 files (compression level 1).
