  • A freely falling probe for small-scale temperature gradients

    Creator:
    Caldwell, Douglas R., Wilcox, Steve D., and Matsler, Mark
    Abstract:
    A light, simple, and fairly inexpensive hand-launched freely falling probe for measuring temperature microstructure was built. The circuitry operates under pressure in a Freon environment; low-power integrated circuits are used as components. The probe is assembled from plastic pipe and fittings and recovered with monofilament fishing line. Standard XBTs are...

  • Long-wave radiation at the ground

    Creator:
    Unsworth, Michael H. and Monteith, J.L.
    Abstract:
    The apparent emissivity of the atmosphere ϵ, defined as the ratio of incoming long-wave radiation to black-body radiation at screen temperature Tₐ, was measured under clear skies in the English Midlands and in the Sudan. At a zenith angle Z the emissivity was given by ϵ(Z) = a + bIn(usec...

  • Aerosol and solar radiation in Britain

    Creator:
    Unsworth, Michael H. and Monteith, J. L.
    Abstract:
    The irradiance of the solar beam was measured on cloudless days at Sutton Bonington in the English Midlands and at sites in north-west Scotland. Total and diffuse fluxes were also measured on some days. An attenuation coefficient for aerosol Ta was defined by S(Ta) = S(o) exp ( - Tam)...

  • Seasonal variation in temperature, salinity, and density over the continental shelf off Oregon

    Creator:
    Huyer, Adriana, 1945-
    Abstract:
    Seasonal variations in the hydrography of the waters over the continental shelf off Oregon were observed in a set of hydrographic data collected along 44º39′N at intervals of a few weeks to a few months from 1961 through 1970. The temperature is determined only partly by the local heating and...

  • Optical and hydrographic observations of the Cromwell Current between 92°00'W and the Galapagos Islands

    Creator:
    Zaneveld, J. Ronald, Pak, Hasong, and Plank, William S.
    Abstract:
    Optical and hydrographic observations were made at two meridional sections across the Cromwell Current at 92°00’ and 91°40’W during February 1969. The distribution of hydrographic and optical properties near the Galapagos Islands is described. Beneath the thermocline the Cromwell Current is characterized by deepening of the light-scattering isolines. Above the...

  • Some aerodynamic features of a cotton canopy

    Creator:
    Bache, D.H. and Unsworth, Michael H.
    Abstract:
    Analysis of profiles measured over irrigated cotton in the Sudan Gezira showed that the crop boundary layer remained stable throughout most of the day. The shape of wind profiles measured within the canopy suggested that momentum was absorbed mostly in the upper layers of the canopy, with the lower regions...

  • Turbulent transfer of sulphur dioxide to a wheat crop

    Creator:
    Fowler, D. and Unsworth, Michael H.
    Abstract:
    Fluxes of sulphur dioxide to wheat were measured over two growing seasons. The deposition velocity, vg, depended primarily on affinities of surfaces for SO2 and varied from less than 0.1 to about 1.5cms−1. Stomata were an important sink, and diurnal changes in stomatal resistance accounted for most of the variation...

    Creator:
    Pak, Hasong and Zaneveld, J. Ronald
    Abstract:
    One hundred and seventy pairs of temperature and light transmission profiles were obtained by simultaneous conductivity-temperature-depth (CTD) and light transmissometer casts in three cruises on the R/V Yaquina over the continental shelf off Oregon. These were analyzed for bottom nepheloid layers (BNL) and bottom mixed layers layers (BML). Supplementing these...

  • Effects of aerosol on the local heat budget of the lower atmosphere

    Creator:
    Glazier, J., Monteith, J.L., and Unsworth, Michael H.
    Abstract:
    The convergence of heat below subsidence inversions was estimated from radiosonde ascents on fine summer days. Sensible heat input from the ground was estimated from measurements of heat fluxes and net radiation over a wheat field. Absorption and back scattering of solar radiation by aerosol throughout the atmosphere were calculated...
