• Abstract
• The A-Train Data Depot (http//disc.gsfc.nasa.gov
  /atdd/)
• The A-Train Data Depot (ATDD) has been
  operational for over a year, successfully serving
  co-registered data from the Cloudsat, Calipso,
  AIRS, and MODIS instruments that are flying in
  succession along the A-Train flight path.
• Of late, OMI data products were added to the
  depot.
• The objectives of the ATDD is to facilitate the
  goals of the A-train by 1. Providing access to
  (eventually) all A-Train datasets, and 2.
  Providing user friendly, quick data visualization
  and exploration to support science data
  discovery.
• The ATDD performs much of the work individual
  researchers would need to do, such as accessing
  remote datasets for convenient download,
  co-registering datasets, and performing these
  functions on specific user requested data of
  interest.
• The ATDD is a virtual data portal/center that
  processes, archives, provides access, visualizes,
  analyzes and correlates distributed atmosphere
  measurements from various A-Train instruments
  along A-Train tracks.
• The ATDD enables the free movement of remotely
  located A-Train data so that they can be combined
  to create consolidated vertical views of the
  Earths atmosphere.
• New Data Products in the A-Train Data Depot
• Recently several new products were added into the
  ATDD for data visualization and access generated
  by the OMI instrument. These include
• OMI/Aura Effective Cloud Pressure and Fraction
  (Raman Scattering) (PI Joanna Joiner)
• OMI/Aura Effective Cloud Pressure and Fraction
  (O2-O2 Absorption) (PI Pepijn Veefkind)
• OMI/Aura Aerosol Extinction and Absorption
  Optical Depth (PI Omar Torres) (Parameters
  FinalAerosolOpticalDepth, FinalAerosolAbsOpticalDe
  pth, UVAerosolIndex, Reflectivity)
• OMI/Aura Ozone, TOMS-like Algorithm (PI P. K.
  Bhartia) (Parameters Aerosol Index, Reflectivity,
  ColumnAmountO3)
• In addition, the Cloudsat product, Radar-only
  liquid/ice water content (PI Richard Austin),
  was added to Giovanni and includes the
  parameters Radar-only Liquid Effective Radius,
  Radar-only Ice Effective Radius, Radar-only
  Liquid Water Content, Radar-only Ice Water
  Content, Radar-only Liquid Water Path, Radar-only
  Ice Water Path.
