MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG V061

MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG V061 provides daily global snow and cloud cover percentages within 0.05-degree (approximately 5 km) grid cells. The data is derived from the MODIS/Terra Snow Cover Daily L3 Global 500m Grid product (MOD10A1.061). This Level-3 dataset is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling global climate and hydrological cycles based on daily snow-covered land area.
• Monitoring seasonal snowpack dynamics based on daily percentage observations.
• Validating regional climate models based on 0.05-degree gridded snow cover data.
• Analyzing long-term cryosphere trends based on the MODIS Collection 6.1 time series.

Strengths

• Provides daily global coverage at a 0.05-degree (approx. 5 km) spatial resolution.
• Derived from the well-established MODIS/Terra MOD10A1.061 product, indicating a consistent processing chain.
• Last updated in March 2026, suggesting ongoing maintenance.

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.
• Data may reflect geographic or temporal bias inherent to the satellite's orbit and cloud cover.
