Lake Balaton Chlorophyll-a Concentrations from Landsat, 1984–2023

Lake Balaton Chlorophyll-a Dataset provides long-term chlorophyll-a concentration data for Lake Balaton, Hungary. The dataset covers approximately 40 years of observations from 1984 to 2023, derived from Landsat 4/5/7/8/9 imagery using Google Earth Engine. It was created by Dr. Huan Li of the HUN-REN Balaton Limnological Research Institute, with a related paper published in 2025.

Use Cases

• Modeling long-term trends in eutrophication based on chlorophyll-a concentration time series.
• Analyzing spatial patterns of algal blooms in Lake Balaton based on 30-meter resolution satellite data.
• Calibrating and validating remote sensing algorithms for inland water quality monitoring.
• Studying the impact of environmental policies and climate on lake ecology over a 40-year period.

Strengths

• Covers a long-term period of approximately 40 years (1984–2023).
• Provides data at a 30-meter spatial resolution.
• Derived from a consistent multi-sensor satellite record (Landsat 4/5/7/8/9).
• Has a clear institutional provenance from a limnological research institute.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Freshness should be verified; the last metadata update was 2026-04-17.
