Ice Cloud Particle Radius from ADEOS-II Satellite

ADEOS-II/GLI L2 Cloud Effective Particle Radius of ice cloud by emission method is a satellite-derived dataset providing the effective radius of ice cloud particles. The Japan Aerospace Exploration Agency (JAXA) produced this data from the GLI sensor onboard the ADEOS-II satellite, with the last update recorded in October 2003. It offers global coverage with a spatial resolution of 0.25 degrees and a 4-day statistical period.

Use Cases

• Analyze global patterns of ice cloud effective particle radius to study cloud-aerosol interactions.
• Validate and improve climate model simulations of cloud microphysics using the 0.25-degree resolution global data.
• Investigate temporal changes in ice cloud properties over the 4-day statistical period covered by the dataset.
• Correlate ice cloud particle radius with other atmospheric variables retrieved from multi-channel radiance (channels 30, 35, 36).

Strengths

• Global spatial coverage with a consistent 0.25-degree resolution.
• Data derived from a dedicated multi-channel optical sensor (GLI) with a 1600 km swath.
• Product is at a defined 'Version 2', indicating a processed and validated state.

Limitations

• Data is temporally stale, with the last update in 2003, limiting analysis of recent climate trends.
• Specific sample size (row count) and data volume are unknown, making computational planning difficult.
• Relies on a specific retrieval method (emission method) which may have inherent algorithmic biases.
