ESA Precursors for Aerosols and Ozone Climate Change Initiative (Precursors_cci): Precursors morning GOME NO2 L3 data products, version 1.1
Abstract
This nitrogen dioxide (NO2) climate data record (CDR) is a newly developed monthly Level 3 product derived from measurements by the Global Ozone Monitoring Experiment (GOME) onboard the European Remote Sensing Satellite (ERS-2). The dataset has been generated within the framework of the ESA Climate Change Initiative (CCI) Precursors for Aerosols and Ozone project.
The GOME NO2 Level 3 product contains comprehensive information, including essential variables (e.g., total, stratospheric, and tropospheric NO2 vertical column densities) and their uncertainties, observation viewing geometries, auxiliary input variables (e.g., surface albedo and cloud properties), and vertically resolved information (e.g., a priori profiles and averaging kernels) for each grid cell. The dataset is available at two spatial resolutions: 0.5° × 0.5° and 1.0° × 1.0°.
The version number is 1.1. The data are provided in NetCDF format.

| Title | Computation process of the gridded nitrogen dioxide (NO2) monthly Level 3 data from GOME/ERS-2 |
| Abstract | The GOME/ERS-2 NO2 Level 3 product was generated using the QA4ECV v1.1 Level 2 product. Only quality-screened Level 2 data were included, applying optimized filtering criteria to ensure data reliability. Monthly Level 3 products were produced by spatial binning onto a regular latitude–longitude grid using an area-weighted averaging approach. The weighting and count vectors are used to consistently apply this weighted averaging during the Level 3 gridding, enabling the calculation of mean values and associated uncertainties. Detailed information on the Level 3 algorithm can be found in the Algorithm Theoretical Basis Document (ATBD). The version number is 1.0. The data are provided in NetCDF format. |
