HS3: Satellite Browse Imagery for Hurricane and Storm Research

April 22, 2013 to September 30, 2014 is the temporal coverage of this collection of browse-only satellite data files from the Hurricane and Severe Storm Sentinel (HS3) field campaign. The dataset includes JPG images containing brightness temperature, rain rate, and RGB composite imagery. Its primary scientific goals were to assess the roles of large-scale environmental processes, the Saharan Air Layer, and deep convection in tropical storm formation and intensification.

Use Cases

• Analyzing storm-scale internal processes based on RGB composite imagery.
• Assessing the role of the Saharan Air Layer (SAL) in tropical storm formation using brightness temperature data.
• Studying the impact of deep convection in the inner-core region of storms via rain rate imagery.

Strengths

• Covers a specific 17-month field campaign period from April 2013 to September 2014.
• Addresses multiple specific scientific goals, including the role of the Saharan Air Layer.
• Available on multiple platforms (datagov, nasa_earthdata), indicating established provenance.

Limitations

• Metadata is incomplete; column names, row counts, and file sizes are unknown across all sources.
• Contains only 'browse only' data files (JPGs), which likely limits quantitative analysis compared to raw sensor data.
• Conflicting license information: one source specifies 'other-license-specified' while another lists 'None'.
