TROPICS05: Neural Network Atmospheric Vertical Profiles

The TROPICS mission constellation provides high-temporal-resolution, nearly all-weather observations of tropical cyclones. This Level-2B dataset contains neural network retrievals of atmospheric vertical temperature profiles up to 20 km and water vapor mixing ratio profiles up to 10 km, derived from passive microwave spectrometer data. Each granule file contains approximately 2880 scans of 81 spots, representing an orbit's worth of data.

Use Cases

• Analyzing three-dimensional temperature profiles for storm intensity forecasting based on seven channels near the 118.75-GHz oxygen line.
• Studying water vapor profiles for humidity structure investigations based on three channels near the 183-GHz water vapor line.
• Investigating precipitation and cloud ice horizontal structure using imagery channels near 90 GHz and 205 GHz.
• Conducting high-value science on tropical cyclones using retrievals performed in all conditions over land and ocean.

Strengths

• Data is produced by a constellation of five identical satellites, providing high temporal resolution observations.
• Retrievals cover both non-precipitating and precipitating conditions over land and ocean, offering broad applicability.
• The dataset provides vertical profiles at two spatial resolutions: temperature at unified F-band and moisture at finer G-band.

Limitations

• Specific column names and dataset size (rows, file size) are not provided across any source, limiting detailed structural understanding.
• The license is ambiguously specified as 'other-license-specified' without further details.
• The last updated metadata is inconsistent, with one source showing a date (2026-04-09) and another showing null.
