Data from 2008 supports the ABACUS project's Work Package 6, providing spatial observations for ecosystem model assimilation. It includes moderate-resolution data from MODIS, MERIS, and AVHRR, high-resolution data from IKONOS and Landsat, airborne radiometry, and ground-based spectral measurements. The dataset was produced by the SCIOPS organization for characterizing vegetation state and analyzing topographic controls at Arctic test sites.
Use Cases
- Assimilating MODIS/MERIS/AVHRR reflectance data into ecosystem models to study broad-scale temporal dynamics.
- Populating a vegetation state database using high spatial resolution data from IKONOS and Landsat (ETM/TM).
- Developing detailed 3D landscape scene models using high-resolution EO data and ground survey topography.
- Performing footprint analysis of tower and aircraft flux data using modeled radiation regimes.
- Monitoring phenology and testing scaling models using ground measurements from ASD spectroradiometers and SKYE sensors.
Strengths
- Integrates multiple data sources: satellite, airborne, and ground-based measurements for a multi-scale perspective.
- Designed to support specific scientific hypotheses (H2, H3, H7) related to topography and scaling within the ABACUS project.
- Includes plans for detailed 3D scene simulation models for accurate vegetation representation.
Limitations
- Specific row counts, column details, and file sizes are unknown.
- Primary data collection appears to have concluded in 2008, limiting temporal relevance for current dynamics.
- Airborne LiDAR data collection was provisional and dependent on external approval.
