    An analysis has been made of the calibrations done during 1990 through 1994 on Rotronic MP- 100 relative humidity sensors (used in the Improved METeorological (IMET) system and sensors built at the Woods Hole Oceanographic ...
  • A comparison of buoy meteorological systems 

    Payne, Richard E.; Huang, Kelan; Weller, Robert A.; Freitag, H. P.; Cronin, Meghan F.; McPhaden, Michael J.; Meinig, C.; Kuroda, Yoshifumi; Ushijima, Norifumi; Reynolds, R. Michael (Woods Hole Oceanographic Institution, 2002-12)
    During May and June 2000, an intercomparison was made of buoy meteorological systems from the Woods Hole Oceanographic Institution (WHOI), the National Oceanographic and Atmospheric Administration (NOAA), Pacific Marine ...
  • Design and validation of a modified Eppley PSP pyranometer 

    Payne, Richard E. (Woods Hole Oceanographic Institution, 1994-11)
    A modified version of the Eppley PSP pyranometer has been designed for use on ships and moored buoys. Seventeen have been built by the Eppley Laboratory for the Upper Ocean Processes Group and deployed on buoys in the ...
  • An improved long-wave radiometer 

    Anderson, Steven P.; Payne, Richard E. (Woods Hole Oceanographic Institution, 2000-12)
    This report describes the development of an improved long-wave radiometer (pyrgeometer) for deployment on ships and buoys. Standard pyrgeometers use a thermopile to measure the temperature gradient between the receiver ...
  • Improved meteorological measurements from buoys and ships (IMET) : preliminary comparison of humidity sensors 

    Crescenti, Gennaro H.; Payne, Richard E.; Weller, Robert A. (Woods Hole Oceanographic Institution, 1990-05)
    Humidity sensors using various principles of operation are evaluated for the potential use at sea on buoys and ships. Thin film capacitive polymer sensors include the Vaisala Humicap HMP-14U (with WHOI electronics), Hy-Cal ...
  • Improved meteorological measurements from buoys and ships (IMET) : preliminary comparison of pyranometers 

    Crescenti, Gennaro H.; Payne, Richard E.; Weller, Robert A. (Woods Hole Oceanographic Institution, 1989-10)
    Three different types of pyranometers (two of each) are tested and evaluated. The sensors include the Eppley Precision Spectral Pyranometer (PSP) which meets the World Meteorological Organization (1965) criteria for a ...
  • Improved meteorological measurements from buoys and ships (IMET) : preliminary comparison of solar radiation air temperature shields 

    Crescenti, Gennaro H.; Payne, Richard E.; Weller, Robert A. (Woods Hole Oceanographic Institution, 1989-10)
    Several different types of solar radiation air temperature shields are evaluated for use at sea on ships and buoys. They include three types of static or Thaller shields, two vane oriented shields, and two fan ventilated ...

    Payne, Richard E.; Crescenti, Gennaro H.; Weller, Robert A. (Woods Hole Oceanographic Institution, 1989-12)
    Stability tests over periods ranging from 3 to 19 months have been carried out on Paroscientific models 215-AT and 760-15A, AIR DB-1A, Rosemount 1201F1B, Setra 270 and Heise 623 electronic barometers. The Paroscientific ...
  • Long-term tests of some inexpensive barometers and results of pressure cycling of an AIR-DB-1A 

    Payne, Richard E. (Woods Hole Oceanographic Institution, 1994-09)
    For approximately 1.5 year, daily observations of barometrc pressure were made with a varety of sensors and compared to readings from a Paroscientific Model 760-16B while all sensors were maintained at a temperature of ...
  • Recognizing problems in shipboard logging meteorology systems 

    Payne, Richard E. (Woods Hole Oceanographic Institution, 2002-08)
