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)
