Aura MLS Daily Hydroperoxy Zonal Means from 2004

August 2004 to current daily zonal mean hydroperoxy data derived from EOS Aura Microwave Limb Sounder radiances. It provides near-global coverage from -85 to 85 degrees latitude spaced every 10 degrees, with a useful vertical range between 21.5 and 0.0464 hPa. The data is produced by NASA's Global Earth Science Data and Information Center (GES DISC).

Use Cases

• Analyze trends in hydroperoxy average and error columns across latitude bands and pressure levels over time.
• Compare daytime and nighttime zonal means objects to study diurnal variations in HO2 concentrations.
• Correlate hydroperoxy data with solar zenith angle and local solar time columns for photochemical modeling.
• Map the spatial distribution of HO2 using the latitude band and pressure level features.

Strengths

• Data coverage spans from August 2, 2004 to current, providing a long-term record.
• Near-global spatial coverage from -85 to 85 degrees latitude spaced every 10 degrees.
• Vertical resolution is about 5 km within the recommended 21.5 to 0.0464 hPa range.

Limitations

• Specific row count, column count, and sample size are unknown.
• Data is limited to zonal means, not providing point-level or gridded observations.
• The useful vertical range is constrained, excluding data above 21.5 hPa and below 0.0464 hPa.
