Description
NASA's STRAT campaign from May 1995 to February 1996 collected in-situ and remote measurements to study global-scale transport. The dataset includes modeled trajectories and meteorological data along the ER-2 flight path, with measurements of HOx, NOy, CO2, ozone, water vapor, temperature, N2O, CH4, CO, HCL, and NO. This data was intended to test 2D and 3D models for assessing the impact of high-speed civil transport exhaust on the stratosphere.
Use Cases
Calibrating two-dimensional and three-dimensional atmospheric transport models based on the campaign's stated objective.
Analyzing trace gas transport rates between the stratosphere and troposphere using the listed chemical species (e.g., N2O, CH4).
Studying dynamical coupling between tropical regions and higher latitudes using wind speed and vorticity data suggested by tags.
Assessing the potential dispersion of aircraft exhaust (HSCT) in the lower atmosphere as described in the campaign goals.
Strengths
Data collection is explicitly stated as complete, providing a finalized record of the campaign.
Covers a defined 10-month time range (May 1995 to February 1996) for seasonal analysis.
Limitations
Column names and precise data structure are unknown, hindering immediate analysis.
Conflicting 'last updated' metadata (1996 vs. 2026) creates uncertainty about data currency.
File formats (BIN, ISO, HTML) are listed without context, indicating potential access or processing hurdles.
