Oceansat-1 OCM and Terra-1/Aqua-1 MODIS instruments provide daily updates on water quality and algal blooms in Lake Pontchartrain following Hurricane Katrina. The dataset likely contains ocean color measurements and true color imagery. Louisiana State University summarized the collection, which includes supporting water sample analysis with HPLC measurements, spectro-radiometer data, and phytoplankton identifications.
Use Cases
- Tracking algal bloom development based on daily satellite ocean color measurements
- Assessing post-hurricane water quality changes based on MODIS true color imagery
- Correlating satellite data with in-situ measurements based on HPLC and spectro-radiometer data
- Identifying phytoplankton species contributing to blooms based on phytoplankton identification data
Strengths
- Data source includes instruments from multiple satellites (Oceansat-1, Terra-1, Aqua-1)
- Collection includes complementary ground-based water sample analysis
- Focus on a specific, significant event (Hurricane Katrina aftermath)
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Last update date is unknown; freshness unverified
