data products summary

AIRS/AMSU-A/HSB will provide instantaneous measurements for the following data products:

Standard Products

  • For the atmosphere, AIRS/AMSU/HSB will provide temperature profiles, humidity profiles, total precipitable water, fractional cloud cover, cloud-top height, and cloud-top temperature.
  • For the land, AIRS/AMSU/HSB will provide skin surface temperature, plus day and night land-surface temperature difference. AIRS will provide outgoing day/night longwave surface flux.
  • For the ocean, AIRS/AMSU/HSB will provide skin surface temperature. AIRS will provide outgoing day/night longwave surface flux.

Research Products

  • For the atmosphere, AIRS/AMSU/HSB will provide a precipitation estimate, and tropopause and stratopause heights. AIRS will provide outgoing longwave spectral radiation and cloud optical thickness.
  • AMSU-A will provide cloud thermodynamic phase (ice/water) and cloud water content.
  • For the land, AIRS/AMSU will provide surface spectral emissivity, surface albedo, and net shortwave flux.
  • For the ocean, AIRS will provide net shortwave flux. AMSU-A will provide sea-ice cover (old/new) and surface (scalar) wind speed.
  • Standard products are distinguished from research products in that the latter will require post-launch verification.
