TROPESS Chemical Reanalysis Surface HNO3 2-Hourly 2-dimensional Product V1 (TRPSCRHNO32H2D) at GES DISC

Metadata Updated: September 18, 2025

The TROPESS Chemical Reanalysis HNO3 2-Hourly 2-dimensional Product contains surface concentrations of nitric acid. 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 2-hourly resolution, and a spatial resolution of 1.125 x 1.125 degrees. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.
