GK-2A Satellite Data: Meteorological Imagery for the Asia-Pacific Region

The Geo-KOMPSAT-2A (GK2A) satellite provides full-disk observations of the Asia-Pacific region every 10 minutes and scans the Korean Peninsula every 2 minutes. It captures data through 4 visible and 12 infrared channels with a high spatial resolution. The data is provided by the Korea Meteorological Administration and hosted on AWS by NOAA.

Use Cases

• Monitoring severe weather events like typhoons based on the flexible target area scanning capability
• Analyzing atmospheric phenomena over the Asia-Pacific region based on full-disk observations
• Tracking volcanic eruptions and ash dispersion based on high-resolution infrared channel data
• Observing space weather conditions based on particle detector and magnetometer readings from the KSEM instrument

Strengths

• High temporal resolution with full-disk scans every 10 minutes and Korean Peninsula scans every 2 minutes
• High spectral resolution with 4 visible and 12 infrared channels
• Operational capability for flexible target area scanning to monitor specific severe events

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count and dataset size are unknown, which may limit suitability assessment
