Nitrogen-oxide emissions from lightning, monthly map

TROPESS Chemical Reanalysis Lightning NOx emissions Monthly 2-dimensional Product V1 (TRPSCRENOXLM2D) at GES DISC
atmosphere NASA GES_DISC Level 4 active
In plain English

What it measures. Monthly maps of the nitrogen-oxide gases (NO and NO2) that lightning strikes pump into the air, covering 2005 through 2021. Lightning is one of the natural sources of these gases, which affect air quality and atmospheric chemistry.

How it's made. It comes from a chemical reanalysis (TCR-2), where a JPL modeling system blends together measurements from several satellites to estimate emissions, rather than being a direct camera or sensor reading.

How & where you'd use it. Researchers use it to understand how much pollution-related nitrogen comes from nature versus human activity, and to improve air-quality and climate models.

Official description

The TROPESS Chemical Reanalysis Lightning NOx emissions Monthly 2-dimensional Product contains nitrogen oxides (NO and NO2) emissions from lightning strikes. The data are part of the Tropospheric Chemical Reanalysis v2 (TCR-2) for the period 2005-2021. TCR-2 uses JPL's Multi-mOdel Multi-cOnstituent Chemical (MOMO-Chem) data assimilation framework that simultaneously optimizes both concentrations and emissions of multiple species from multiple satellite sensors. The data files are written in the netCDF version 4 file format, and each file contains a year of data at monthly resolution, and a spatial resolution of 1.125 x 1.125 degrees. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.
