Description
INTEX-B was an eight-week field study from March to April 2006 designed to quantify the intercontinental transport of pollution and its impact on air quality and climate. The dataset includes Multi-angle Imaging SpectroRadiometer (MISR) satellite products, such as geometric parameters and ellipsoid-projected radiance, for the study region. It aims to validate satellite observations and map emissions of trace gases and aerosols across North America, the Pacific, and the Atlantic.
Use Cases
Modeling transpacific transport of Asian pollution based on the study's goal to quantify its impact on North American air quality.
Validating satellite observations of tropospheric composition using the MISR geometric and radiance data products.
Analyzing aerosol and cloud properties over the INTEX-B region based on MISR's multi-angle, multi-spectral imaging capabilities.
Mapping trace gas emissions and relating atmospheric composition to sources and sinks as described in the project's scientific goals.
Strengths
Data originates from a coordinated NASA field campaign with defined scientific goals and an eight-week operational period.
Includes specialized MISR satellite products with observations from nine different camera angles and four spectral bands.
Released under a permissive CC-BY-4.0 license, facilitating reuse and analysis.
