Monthly Mean Wind Tendency Assimilations on 42 Pressure Levels

1980 to present monthly mean assimilations of wind tendencies produced by NASA's Global Modeling and Assimilation Office. This collection contains 3D data on 42 pressure levels, including total wind analysis tendency and tendencies due to dynamics and turbulence. The dataset is generated using the Goddard Earth Observing System Model version 5.12.4.

Use Cases

• Analyzing the tendency of eastward wind due to dynamics to study large-scale atmospheric forcing mechanisms.
• Validating climate model outputs against the total northward wind analysis tendency assimilations.
• Investigating vertical wind profiles by comparing tendencies across the 42 documented pressure levels.
• Studying turbulent contributions to wind patterns using the tendency of eastward wind due to turbulence feature.

Strengths

• Covers a long-term period from 1980 to the present, enabling climate trend analysis.
• Provides data on 42 distinct pressure levels for detailed vertical atmospheric analysis.
• Produced by NASA GMAO using the GEOS 5.12.4 model, an authoritative source for reanalysis.

Limitations

• Data has a latency of approximately 3 weeks after the end of each month, not suitable for real-time applications.
• Specific row counts, file sizes, and spatial resolution details beyond the 0.625 x 0.5 degree grid are not provided in the input.
