CAMEX-4 Airborne Lidar Water Vapor and Aerosol Profiles

LIDAR Atmospheric Sensing Experiment data provides vertical profiles of water vapor, aerosols, and clouds throughout the troposphere. The dataset was collected by NASA's airborne DIAL system aboard a DC-8 aircraft during the CAMEX-4 campaign. It includes simultaneous nadir and zenith measurements from 2001.

Use Cases

• Analyzing vertical distribution of water vapor using DIAL absorption line measurements.
• Studying aerosol backscatter and cloud properties throughout the troposphere.
• Validating atmospheric models with simultaneous above- and below-aircraft profile data.
• Investigating humidity gradients and atmospheric processes during the CAMEX-4 field campaign.

Strengths

• Data collected using a Differential Absorption Lidar (DIAL) system, a direct and precise measurement technique.
• Provides simultaneous vertical profiles above and below the aircraft from nadir and zenith operating modes.
• Measures multiple atmospheric constituents: water vapor, aerosols, and clouds.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date: one platform lists 2026-03 13, while another lists 2001-09-25.
