Ozone adjustment in the reanalysis, every 6 hours

TROPESS Chemical Reanalysis O3 Increment 6-Hourly 3-dimensional Product V1 (TRPSCRO3I6H3D) at GES DISC
atmosphere NASA GES_DISC Level 4 active
In plain English

What it measures. The ozone increment, meaning the adjustment the reanalysis applies to its ozone estimate when it folds in satellite observations, recorded at different altitudes every six hours.

How it's made. Generated by a reanalysis that merges multiple satellite measurements with chemistry models over 2005-2021, on a global grid at 27 altitude levels.

How & where you'd use it. Primarily a diagnostic for researchers checking how much the observations are nudging the model's ozone, rather than a direct ozone measurement for general use.

Official description

The TROPESS Chemical Reanalysis O3 Increment 6-Hourly 3-dimensional Product contains the ozone increment by data assimilation. 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 6-hourly resolution, and a spatial resolution of 1.125 x 1.125 degrees at 27 pressure levels between 1000 and 60 hPa. The principal investigator for the TCR-2 data is Miyazaki, Kazuyuki.
