FLUAMAZON: Atmospheric Thermodynamics Over Amazonia

FLUAMAZON Experiment data includes meteorological measurements collected via radiosondes to examine moisture flux from the northern coast of South America into central Amazonia. Measurements were taken simultaneously at five locations—Alcantara, Belem, Oiapoque, Manaus, and Alta Floresta—from November 23 to December 21, 1989, during the transition between dry and humid seasons. The dataset supports studies on the atmospheric thermodynamic structure over the Amazon region.

Use Cases

• Analyzing moisture flux patterns based on atmospheric water vapor measurements.
• Studying seasonal transition dynamics using data from the dry-to-humid season period.
• Examining atmospheric thermodynamic structure via radiosonde-derived pressure and temperature profiles.
• Comparing upper-level wind patterns across five simultaneous measurement sites.

Strengths

• Provides simultaneous atmospheric profiles from five distinct geographic locations.
• Captures a specific, defined transition period (dry to humid season) over 29 days in 1989.

Limitations

• Column names and exact data structure are not specified in the provided metadata.
• Conflicting last-updated dates exist between platforms (1989 vs. 2026), suggesting potential metadata issues.
• Dataset scale (row count, file size) is unknown.
