MISR Derived Case Study Data for Iceland Volcanic Eruptions (Eyjafjallajokull, Grimsvotn,

NASA MISR-derived analysis data from three Icelandic volcano eruptions: Eyjafjallajokull 2010, Grimsvotn 2011, and Holuhraun 2014-2015. The dataset includes files for each MISR overpass, containing plume height records, wind vectors, and aerosol property retrievals. The data is discussed in a 2020 paper by Flower and Kahn published in the Journal of Geophysical Research: Atmospheres.

Use Cases

• Analyzing volcanic plume height evolution based on MINX-derived height records from red and blue spectral bands.
• Studying aerosol particle properties like optical depth and non-spherical fraction based on MISR Research Aerosol algorithm outputs.
• Modeling downwind dispersion of volcanic ash based on wind vectors retrieved at plume elevation.
• Comparing aerosol characteristics across different Icelandic eruptions based on qualitative radiometric particle property information.

Strengths

• Data covers three distinct volcanic eruptions over a five-year period (2010-2015).
• Includes multiple file types per observation, such as map views, profile plots, histograms, and text files of digital values.
• Derived from NASA's MISR instrument and supported by published peer-reviewed research.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• RA plume retrievals are limited when cloud cover was widespread or solar radiance was insufficient, leading to missing files.
• Column-level documentation is absent; field semantics must be inferred after download.
