LBA-ECO CD-01: Meteorological and Upper Air Data for the Amazon Basin

LBA-ECO CD-01 contains meteorological data collected around the confluence of the Tapajós and Amazon Rivers near Santarém, Brazil, in July and August 2001. Measurements from five local stations include boundary layer and upper air data from sodar, pilot balloons, and radiosondes, which recorded pressure, temperature, humidity, and wind. The dataset includes 41 comma-delimited data files, plus companion weather forecasts, 42 satellite images, and CPTEC model output files.

Use Cases

• Analyzing vertical profiles of temperature and humidity based on radiosonde data.
• Studying wind patterns and atmospheric stability using sodar and pilot balloon measurements.
• Validating regional climate models with the provided CPTEC Global Analysis output.
• Correlating ground-based meteorological observations with satellite imagery from the same period.

Strengths

• Contains data from five distinct measurement stations, providing spatial context.
• Includes 41 primary data files plus 42 satellite images and model outputs, offering multiple data modalities.
• Supported by detailed companion files like weather forecasts and satellite image compilations.

Limitations

• Column names and a precise row count are not provided in the available metadata.
• Conflicting last-updated dates exist between platforms (2001 vs. 2026), suggesting potential metadata inconsistencies.
• The dataset's temporal coverage is limited to a two-month period in 2001.
