VJ104ANC: Daily Global Aerosol and Atmospheric Data

VIIRS/JPSS1 Aerosol Daily L3 Global 0.05 Deg CMG provides daily, global satellite-derived atmospheric data at a 0.05-degree resolution. The product contains five science data layers, including aerosol optical depth, air temperature, ozone, and water vapor, derived from daytime Level 2 observations. Its primary purpose is to serve as input for climate simulation models.

Use Cases

• Modeling global aerosol transport and climate impact based on aerosol optical depth data.
• Analyzing tropospheric ozone levels for air quality and atmospheric chemistry studies.
• Incorporating daily water vapor and air temperature data into regional climate simulations.
• Tracking long-term atmospheric composition changes using the time-series data starting in 2018.

Strengths

• Provides data at a high spatial resolution of 0.05 degrees for global coverage.
• Contains five distinct science data set (SDS) layers for multi-variable analysis.
• Data record has a defined start date of January 5, 2018, providing a multi-year time series.

Limitations

• Key metadata such as column names, row counts, and file sizes are unspecified across all sources.
• Sources conflict on license information, with 'other-license-specified' on one platform and 'None' on another.
• Data is derived only from daytime observations, which may limit diurnal cycle analysis.
