Abstract

Space-borne measurements of tropospheric nitrogen dioxide (NO2) are up to 10x more sensitive to upper tropospheric NO2 than near-surface NO2 over low reflectivity surfaces. This make the modeling of lightning NO2 in the a priori profiles imperative to accurately retrieve NO2 over regions with significant lightning activity. This is quantified in our work "Quantification of the effect of modeled lightning NO2 on UV-visible air mass factors." This dataset contains the NO2 retrievals used in Section 3.3 of that paper to demonstrate the effect in a real retrieval.

Methods

These retrieval products were produced using version 2.1C of the BEHR retrieval (http://behr.cchem.berkeley.edu/) with custom profiles simulated with varying amounts of lightning NO emissions input instead of the standard profiles and a correction to the temperature profile look up.

Usage Notes

This data is stored as HDF version 5 files. For each amount of lightning NO emissions, data is provided at the native OMI pixels and regridded to 0.05 degree resolution. Fill values are given within each dataset, and should be removed before using the data.
