North American AVHRR Satellite Imagery at 1km Resolution

AVHRR satellite data provides 1km spatial resolution imagery in five spectral bands from visible to thermal infrared. Coverage is limited to the North American continent, with data archived since March 5, 2000. The dataset is collected by a ground station at the University of North Dakota and held by the Upper Midwest Aerospace Consortium.

Use Cases

• Classify land cover types using the five spectral bands of 1km resolution imagery.
• Analyze sea surface temperature patterns from the thermal infrared band data.
• Monitor atmospheric aerosol or cloud properties across the continent using visible and infrared band combinations.
• Track vegetation health and phenology over time using the visible and near-infrared bands.

Strengths

• Provides 1km spatial resolution for detailed continental-scale analysis.
• Includes data across five spectral bands enabling multi-spectral applications.
• Archival record spans from March 2000, offering a multi-year time series.

Limitations

• Spatial coverage is limited only to the North American continent.
• Data is stored on DAT tape, which may require specialized hardware or conversion for modern access.
