TROPESS Chemical Reanalysis NO: Global 3D Nitric Oxide Concentrations, 2005-2021

Global vertical concentrations of nitric oxide (NO) from the Tropospheric Chemical Reanalysis v2 (TCR-2). The dataset provides 6-hourly, 3-dimensional fields at 27 pressure levels between 1000 and 60 hPa, with a spatial resolution of 1.125 x 1.125 degrees, generated using JPL's MOMO-Chem data assimilation framework that optimizes concentrations and emissions from multiple satellite sensors. Data covers the period from 2005 to 2021 and is stored in netCDF version 4 files, with each file containing a full year of data.

Use Cases

• Analyzing global trends in nitric oxide concentrations based on the 17-year time series.
• Validating atmospheric chemistry models using the assimilated, 3-dimensional fields at 27 pressure levels.
• Studying pollutant transport and emission source attribution using the optimized concentration and emission data from the MOMO-Chem framework.
• Investigating diurnal and seasonal cycles of NO using the 6-hourly temporal resolution.

Strengths

• Provides a 17-year continuous record (2005-2021) for long-term trend analysis.
• Offers high vertical resolution with data at 27 distinct pressure levels between 1000 and 60 hPa.
• Uses a sophisticated data assimilation framework (MOMO-Chem) that simultaneously optimizes concentrations and emissions from multiple satellite sources.

Limitations

• Specific column names and data volume (size/rows) are not documented in the provided metadata.
• The license is ambiguously described as 'other-license-specified' without explicit terms.
• Spatial resolution (1.125 degrees) may be too coarse for regional-scale studies.
