POLARIS Campaign ER-2 Aircraft Atmospheric Chemistry and Trajectory Data

1997 data from the joint NASA-NOAA POLARIS campaign, designed to study summer polar stratospheric ozone loss. The dataset contains modeled trajectories and meteorological data along the flight path of the high-altitude ER-2 aircraft, which collected measurements of key atmospheric species and variables. Observations were used to constrain stratospheric computer models for evaluating ozone changes due to chemistry and transport.

Use Cases

• Analyzing the relationship between long-lived tracers (e.g., N2O, CH4) and summertime transport questions.
• Modeling ozone changes by using measured species from reactive nitrogen (NOy), halogen (Cly), and hydrogen (HOx) reservoirs as constraints.
• Studying meteorological conditions (pressure, temperature, wind) alongside chemical measurements from aircraft, balloon, and satellite platforms.
• Investigating the photochemical processes causing ozone decreases using data from specific instruments like Laser Absorption and Gas Chromatography.

Strengths

• Data collection is complete for the 1997 campaign, providing a focused temporal snapshot.
• Integrates multi-platform measurements from aircraft, balloons, satellites, and ground-sites.
• Covers a specific mission goal to understand ozone level changes from spring to autumn.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source.
• Sources conflict on the last updated date (1997-09-26 vs. 2026-03-12), indicating potential metadata inconsistency.
