MAC04S1 is a subset of MODIS/Aqua Level-2 aerosol data, spatially constrained to a 200 km wide swath along the CloudSat satellite's field of view. The product provides retrieved aerosol optical properties, mass concentration, and ancillary parameters globally. The subset is produced by the GES DISC organization and was last updated in February 2018.
Use Cases
- Analyze aerosol optical thickness along CloudSat's flight path for cloud-aerosol interaction studies.
- Study aerosol size distribution over ocean and land regions within the 200 km cross-track subset.
- Use quality assurance parameters to filter data for reliable atmospheric modeling.
- Correlate mass concentration measurements with other atmospheric datasets from the CloudSat track.
Strengths
- Provides global coverage over ocean and near-global coverage over land.
- Cross-track width is precisely defined as 21 pixels, corresponding to about 200 km.
- Along-track, all MODIS pixels from the original MYD04_L2 product are preserved.
Limitations
- Data product was last updated in 2018, potentially limiting temporal analysis of recent trends.
- Specific row count, column details, and file formats are unknown.
- The subset's spatial coverage is limited to a corridor along the CloudSat track.
