  • Fall 2001, 2003-07 (6 years) 20˚S, 75-85˚W (Stratus). 2001, 2003-04, ±10˚N, 95˚ and 110˚W (TAO/PACS).

  • Observe:

    • Surface meteorology

    • Turbulent and radiative fluxes

    • Cloud vertical structure: top, base, and LCL.

    • Rawinsonde profiles

    • Column water vapor and liquid water path

    • Aerosols

  • NOAA/ESRL operates and maintains a number of systems on the RHB

    • Turbulent and radiative fluxes

    • Microwave radiometer and ceilometer

    • Cloud, wind, and precipitation radars

    • Radiosondes

    • Occasional co-deployment with lidar systems

  • NOAA/ESRL plans numerous deployments the next 3-5 years

  • Deployments depend upon funding (e.g., radiosondes)

  • Other ships are used (UNOLS, Ka’imimoana, USCG ice breakers, etc)
