TROPESS TCR-2: Monthly Zonal Wind at 27 Pressure Levels

27 pressure levels between 1000 and 60 hPa provide vertical profiles of the zonal wind component (u vector) from 2005 to 2021. This product is part of the Tropospheric Chemical Reanalysis v2 (TCR-2), generated using JPL's MOMO-Chem data assimilation framework that optimizes concentrations and emissions from multiple satellite sensors. Data are stored in netCDF files with a spatial resolution of 1.125 x 1.125 degrees.

Use Cases

• Analyzing vertical wind structure for atmospheric dynamics studies based on the 27 pressure levels.
• Assessing chemical transport in the troposphere based on the assimilation framework that optimizes concentrations.
• Validating meteorological models using the assimilated, multi-sensor zonal wind data.
• Studying long-term trends in zonal wind patterns from 2005 to 2021.

Strengths

• Provides a 17-year continuous record from 2005 to 2021.
• Offers high vertical resolution with data at 27 distinct pressure levels.
• Uses a sophisticated assimilation framework (MOMO-Chem) integrating multiple satellite sensors.

Limitations

• Column names and exact data structure within the netCDF files are not documented.
• The dataset's size and row count are unspecified across all sources.
• License details are ambiguous, listed only as 'other-license-specified'.
