TROPESS Chemical Reanalysis NO Monthly 3-dimensional Product V1 (TRPSCRNOM3D) at GES DISC

TROPESS Chemical Reanalysis v2 (TCR-2) provides a 17-year global record of nitric oxide concentrations using JPL's MOMO-Chem data assimilation framework. The dataset offers monthly, three-dimensional data at 27 pressure levels between 1000 and 60 hPa, with a spatial resolution of 1.125 degrees. This reanalysis simultaneously optimizes both concentrations and emissions from multiple satellite sensors.

Use Cases

• Analyzing long-term trends in nitric oxide concentrations based on the 2005-2021 time series
• Studying vertical distribution of nitric oxide using the 27 pressure level profiles
• Assessing global emission patterns through the assimilated concentration and emission data
• Validating atmospheric chemistry models with the 1.125-degree gridded reanalysis product

Strengths

• Provides a 17-year continuous record (2005-2021) for longitudinal analysis
• Offers high vertical resolution with 27 distinct pressure levels
• Utilizes a sophisticated multi-species, multi-model assimilation framework (MOMO-Chem)
• Available on multiple authoritative platforms (NASA EarthData, Data.gov), indicating validation and importance

Limitations

• Column names and detailed variable metadata are not provided in the available descriptions
• The dataset's license is ambiguously listed as 'other-license-specified' without details
• The spatial resolution of 1.125 degrees may be coarse for regional-scale studies
