Description
Over 15 years of continuous atmospheric measurements began in October 2006 at the Cape Verde Atmospheric Observatory. The dataset includes concentrations of halocarbons, aerosols, methane, carbon dioxide, nitrous oxide, and other trace gases. It is maintained by researchers from SCIOPS.
Use Cases
Analyze trends in atmospheric methane and carbon dioxide concentrations from flask sampling data starting January 2007.
Study the seasonal variability of atmospheric DMS (dimethyl sulfide) measured via dual channel GC-FID since October 2006.
Correlate aerosol measurements with concurrent halocarbon data from GC-MS instruments available since May 2007.
Model the transport of pollutants by examining time-series data for ethene, isoprene, and methanol from GC-FID instruments.
Validate remote sensing data using ground-based measurements of carbon monoxide from UV Fluorescence instruments operational since October 2006.
Strengths
Long-term continuous record spanning over 15 years from October 2006 onward.
Multi-instrument measurements for key gases like methane, CO2, and CO providing cross-validation.
Data collected from a fixed observatory location at 17N, 25W, ensuring consistent geographic context.
Limitations
Specific row counts, file sizes, and data formats are unknown.
Data availability start dates vary per measurement type (e.g., May 2007 for halocarbons, June 2008 for some CO2), creating incomplete early records.
The description does not specify data resolution (e.g., hourly, daily), which limits analysis granularity.
