Hurricane Satellite Imagery from AVHRR Radiometer

1979 to present data provides twice daily global observations from the Advanced Very High Resolution Radiometer (AVHRR). This dataset extends the HURSAT collection for applying the Objective Dvorak technique, with data gridded around tropical cyclone centers. It is provided by NOAA_NCEI and includes hurricanes from all tropical cyclone-prone basins.

Use Cases

• Apply the Objective Dvorak technique using 4km spatial resolution GAC data to estimate tropical cyclone intensity.
• Analyze hurricane development patterns from mapped mosaics and orbital swaths of brightness composites.
• Study long-term tropical cyclone trends using time-series data from the stable AVHRR instrument spanning over 40 years.
• Model cyclone center circulation using gridded satellite data fixed on tropical cyclone centers.
• Compare spectral band data from visible, near infrared, and thermal infrared channels across different cyclone events.

Strengths

• Twice daily global observations provide high temporal frequency.
• Data spans from 1979 to present, offering a long-term record.
• Spatial resolution of 4km corresponds to the intended resolution of the Objective Dvorak technique.
• Data is provided in a self-documenting NetCDF format following standard conventions.

Limitations

• The last documented update was in 2009, indicating potential staleness for recent events.
• Specific row counts, sample sizes, and file sizes are unknown.
• The description does not specify the exact number of hurricanes or events included.
