Lake Constance Chlorophyll Concentration from MERIS Satellite Daily Maps

Daily maps of chlorophyll concentration in Lake Constance derived from MERIS satellite imagery. The product was developed by DLR-DFD and the GKSS Research Centre Geesthacht within the MAPP project, with data pre-processed by DLR-DFD. The dataset was last updated in March 2010.

Use Cases

• Analyze temporal trends in chlorophyll-a concentration to monitor algal bloom dynamics in Lake Constance.
• Validate regional water quality models using daily satellite-derived chlorophyll concentration maps.
• Correlate chlorophyll levels with other environmental parameters using the spectral data from 412-900 nm.
• Study spatial distribution patterns of phytoplankton biomass across Lake Constance at a 300-meter resolution.

Strengths

• Data provides daily temporal resolution for monitoring short-term changes.
• Spatial resolution of 300 meters allows for analysis of distribution patterns across the lake.
• Derived from MERIS sensor data covering the visible-near infrared spectral region (412-900 nm).

Limitations

• Dataset is temporally stale, with last update recorded in March 2010.
• Specific row count, sample size, and geographic coverage details for Lake Constance are unknown.
• Product availability depended on successful MERIS data reception and positive checks for suitable water area.
