PEM-Tropics-B: Aircraft Meteorology and Navigation Data

PEM-Tropics-B_MetNav_AircraftInSitu_P3B_Data contains in-situ meteorology and navigation measurements from the NASA P-3B aircraft during the Pacific Exploratory Mission Tropics B campaign in March-April 1999. The dataset features data from the Turbulent Air Motion Measurement System (TAMMS) and was collected to assess anthropogenic impact on tropospheric oxidizing power and atmospheric sulfur chemistry over the tropical Pacific. It is part of the broader NASA Global Tropospheric Experiment series from 1983-2001.

Use Cases

• Analyzing atmospheric sulfur chemistry and dimethyl sulfide oxidation based on measured intermediate products.
• Contrasting biomass burning influence between dry and wet seasons using data from PEM-Tropics A and B phases.
• Studying turbulent air motion and wind fields using the Turbulent Air Motion Measurement System (TAMMS) data.
• Modeling the impact of marine biogenic emissions on aerosol loading and radiative effects.
• Assessing tropospheric oxidizing power by analyzing hydroperoxyl radical and ozone measurements.

Strengths

• Data collection is complete, covering the full PEM-Tropics B campaign period.
• Part of a long-term NASA experiment series (Global Tropospheric Experiment) spanning 1983-2001.
• Features specific, high-value instrumentation like the Turbulent Air Motion Measurement System (TAMMS).

Limitations

• Column names and data structure are not detailed in the provided metadata.
• Exact row count and file size are unknown, limiting assessment of dataset scale.
• The dataset title mentions 'PHIPS IMPACTS V1', but the descriptions are for PEM-Tropics-B, indicating a potential metadata conflict or mislabeling.
