Lidar Aerosol Measurements from Geesthacht, 1991-1994

From August 1991 to March 1994, the Raman Lidar Database contains data from approximately 150 measurement nights, with about 5 nights per month, recorded in Geesthacht. For each event, it provides aerosol absorption and extinction coefficients between 3 km and 30 km altitude, with a maximum height resolution of about 60 meters. The dataset is hosted on NASA EarthData and was last updated in March 1994.

Use Cases

• Modeling vertical aerosol profiles based on extinction coefficients.
• Analyzing temporal trends in atmospheric composition based on multi-year monthly measurements.
• Calibrating satellite aerosol data based on high-resolution ground-based lidar measurements.
• Studying stratospheric aerosol layers based on data up to 30 km altitude.

Strengths

• Approximately 150 measurement nights provide a multi-year temporal series.
• High vertical resolution of about 60 meters for detailed atmospheric profiling.
• Data covers a significant altitude range from 3 km to 30 km.

Limitations

• Last updated 1994-03-31 23:59:59.999000; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
