TRPSCRV6H3D: Tropospheric Meridional Wind Reanalysis 2005-2021

2005-2021 global atmospheric data provides the 6-hourly meridional (north-south) wind component at 27 vertical pressure levels. This dataset is part of the Tropospheric Chemical Reanalysis v2 (TCR-2), generated using JPL's MOMO-Chem data assimilation framework to optimize chemical concentrations and emissions. It has a spatial resolution of 1.125 x 1.125 degrees and is stored in netCDF4 format.

Use Cases

• Validating and initializing atmospheric chemistry transport models based on the assimilated 3D wind fields.
• Analyzing long-term trends in meridional wind patterns from the 17-year time series.
• Studying vertical transport of chemical species using the 27-pressure-level wind structure.
• Correlating wind dynamics with pollutant distributions from the broader TCR-2 reanalysis.

Strengths

• Provides a 17-year continuous record (2005-2021) for longitudinal climate studies.
• Offers high vertical resolution with data at 27 distinct pressure levels between 1000 and 60 hPa.
• Uses a sophisticated multi-species data assimilation framework (MOMO-Chem) to produce constrained meteorological fields.
• Has a consistent 6-hourly temporal and 1.125-degree spatial resolution for global coverage.

Limitations

• Specific row/record counts and total dataset size are not provided in the available metadata.
• The license is ambiguously described as 'other-license-specified' without explicit terms.
• Column names and detailed variable attributes within the netCDF files are not listed.
