Dataset Description: Daily Gap-Filled 550 nm Deep Blue AOD over CONUS

This dataset provides daily netCDF files (YYYYMMDD.nc) containing gap-filled aerosol optical depth (AOD) at 550 nm over the continental United States (CONUS), as described in Lee et al. (2025). Each file includes three key data arrays:

  • deep_blue_combined_aod550: Original Deep Blue AOD retrievals from VIIRS and MODIS sensors.
  • unet_aod550: Modeled AOD estimates generated using the UNet 3+ deep learning architecture.
  • gap_filled_aod550: Final gap-filled AOD product that integrates observed and modeled data to provide spatially continuous coverage.

This dataset supports research in air quality, climate modeling, and satellite data assimilation by offering high-resolution, daily AOD estimates with improved spatial completeness.
