LBA-ECO CD-03: Mesoscale Rainfall and River Breeze Data, Santarem Region

LBA-ECO CD-03 contains rainfall data from a network of 38 rain gauges near the Tapajos-Amazon river confluence in the eastern Amazon Basin from 1998 to 2006. The dataset includes daily totals and analysis of local meteorological phenomena, such as river breeze effects on convective and nocturnal precipitation patterns. It also compares ground observations with 0.25-degree CMORPH satellite-derived rainfall estimates.

Use Cases

• Analyzing river breeze impacts on local rainfall distribution based on station proximity data.
• Validating and calibrating satellite-derived rainfall products (e.g., CMORPH) using collocated ground station measurements.
• Investigating diurnal precipitation cycles, specifically the trade-off between afternoon convective and nocturnal rainfall near large rivers.
• Studying spatial rainfall gradients and orographic effects north of the Amazon River.
• Assessing the performance of tipping bucket rain gauges in a high-rainfall tropical regime.

Strengths

• Data is based on a network of 38 rain gauges, providing a specific spatial density for analysis.
• Includes a long-term temporal coverage of 8 years (1998-2006), allowing for seasonal and interannual trend analysis.
• Combines in-situ measurements with satellite data (CMORPH) for cross-validation and multi-scale study.

Limitations

• Specific column names and data structure are not provided, limiting precise understanding of the dataset's format.
• Conflicting last-update dates exist between sources (2006 on NASA Earthdata vs. 2026 on Data.gov), creating uncertainty about data currency.
• The spatial extent is limited to the Santarem region, which may not be representative of the entire Amazon Basin.
