Ranu Lamongan 800-Year Drought Index from Lake Sediment

An 805-year paleolimnological record from Ranu Lamongan in East Java, Indonesia, provides a drought index derived from lake sediment parameters. The dataset covers the period from 805 to 0 calendar years before present (BP). It is archived and maintained by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstructing historical drought frequency and intensity in East Java using the derived drought index time series.
• Analyzing centennial-scale climate variability in Indonesia by examining trends in the paleolimnological parameters.
• Calibrating regional climate models by comparing the 805-year sediment record with instrumental climate data.
• Investigating the relationship between volcanic activity in Java and local hydroclimate as recorded in lake sediment layers.

Strengths

• 805-year continuous temporal coverage from 805 to 0 BP.
• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Specific sample resolution, column details, and data size are unknown from the provided metadata.
• The dataset's last update date is listed as 1950-01-01, indicating potentially stale metadata.
