NAMMA Senegal Rain Gauge Network: One-Minute Rainfall Accumulation

Forty rain gauge sites across Senegal recorded one-minute rainfall accumulation data during the NASA African Monsoon Multidisciplinary Analyses (NAMMA) field campaign. This mission, based in the Cape Verde Islands, aimed to study African Easterly Waves and Mesoscale Convective Systems starting in August 2006. The dataset includes site locations and photographs documented in an accompanying PDF file.

Use Cases

• Analyzing high-temporal-resolution precipitation rates and amounts from 40 distinct sites.
• Correlating ground-based rain gauge data with satellite or aircraft observations of African Easterly Waves.
• Studying the spatial distribution and intensity of rainfall events during the 2006 West African monsoon season.
• Validating hydrological or atmospheric models for the Senegalese region using field campaign data.

Strengths

• Data originates from a focused NASA field campaign with a defined scientific mission.
• Network provides high-frequency, one-minute temporal resolution for precipitation events.
• Includes documented site locations and photographs for 40 gauge stations.

Limitations

• Core data file formats, column names, and exact row counts are unspecified across all sources.
• Conflicting 'last updated' dates exist between platforms (2006-09-30 and 2026-03 12).
• The license is ambiguously noted as 'other-license-specified' without clear terms.
