NAMMA Mobile Laboratory Atmospheric Measurements from Cape Verde

Instrument data characterize atmospheric constituents from the NASA African Monsoon Multidisciplinary Analyses (NAMMA) campaign. Measurements include radiances, irradiances, back scatter profiles, atmospheric state variables, aerosol properties, particle size distributions, trace gas concentrations, and sky images. The field research investigation was based in the Cape Verde Islands and commenced in August 2006.

Use Cases

• Analyzing aerosol optical depth and backscatter to study Saharan dust transport.
• Correlating trace gas concentrations with meteorological variables like wind speed and atmospheric pressure.
• Studying cloud microphysics using particle size distribution data.
• Validating satellite retrievals with in-situ measurements of solar irradiance and longwave radiation.
• Investigating the structure of convective systems using time-series atmospheric state and sky imagery data.

Strengths

• Data originates from a major NASA field campaign (NAMMA) with a defined scientific mission.
• Includes measurements from a diverse suite of in-situ and remote sensing instruments (e.g., radiometers, lidar, gas monitors).
• Covers multiple atmospheric parameters including aerosols, trace gases, radiation, and meteorology.

Limitations

• Specific row counts, file sizes, and a complete column list are unavailable from all sources.
• Sources conflict on the last updated date (2006-09 26 vs. 2026-03-12), suggesting potential metadata errors.
• License is ambiguously listed as 'other-license-specified' without explicit terms.
