Terra Basic Fusion (TerraFusion) Multisensor Earth Observation Dataset

Overview

The Terra Basic Fusion (TerraFusion) dataset combines Level-1 radiance data from all five instruments aboard NASA’s Terra Earth Observing System satellite into a single fused product. It supports high-level studies of climate, clouds, aerosols, land, and atmosphere with perfectly co-registered observations.

Instruments Fused

• MODIS: Moderate Resolution Imaging Spectroradiometer for global land/ocean/atmosphere imaging.
• MISR: Multi-angle Imaging SpectroRadiometer for multi-view geometry and aerosol retrievals.
• MOPITT: Measurements of Pollution in the Troposphere (e.g., CO).
• CERES: Clouds and the Earth’s Radiant Energy System (radiation budget).
• ASTER: Advanced Spaceborne Thermal Emission and Reflection Radiometer for high-resolution land imaging.

Key Characteristics

• Radiances from all five instruments geolocated and fused onto a common grid.
• Coverage from 2000–2015 with planned extensions to later years.
• Designed for high-performance analysis on the cloud via AWS.

Use Cases

• Climate and energy budget studies combining radiation, clouds, and surface properties.
• Aerosol–cloud interaction research using multi-angle and spectral information.
• Training ML models for land cover, cloud classification, and atmospheric retrievals.
