Improved Meteorological Measurements from Ships and Buoys for the World Ocean Circulation Experiment (WOCE)

该项目的目标是提高由浮标和船舶进行的气象测量和海气通量估算的准确性、可靠性和可用性。具体地说，在该项目的三年期间，将努力：(L)重点改进用于浮标和船舶气象测量的传感器，重点是增加湿度和长波辐射，并减少和量化长波和短波辐射测量中的误差。(2)使用市面上可买到的IBM PC兼容处理器以及运动和姿态传感器进行智能数据采集；并采用市面上可买到的硬件来遥测浮标和船舶的数据。处理器的能力和灵活性将被用来进一步减少测量中的误差。(3)通过进行实验室、码头和现场校准和相互比较，量化传感器进行的基本测量和由此估计的海-气通量的准确性。(4)将浮标气象系统和船舶气象系统部署在当地专用的地面系泊设备和有机会使用的船舶上进行长期测试，以便发现并纠正在这种使用中会降低测量的准确性和可靠性的问题。该项目的工作包括与加州大学圣地亚哥分校和南加州大学的科学家进行强有力的科学和技术合作。这项工作由分包合同提供支持。整个项目是世界海洋环流实验(WOCE)的长期牵头项目。

The goal of this project is to improve the accuracy, reliability, and availability of meteorological measurements and air-sea flux estimates made from buoys and ships. Specifically, over the three year period of the project, the effort would: (l) Focus on improving the sensors used for meteorological measurements from buoys and ships with emphasis on adding humidity and longwave radiation, and on reducing and quantifying errors in both long and shortwave radiation measurements. (2) Use a commercially available, IBM PC compatible processor and motion and attitude sensors for intelligent data acquisition; and incorporate commercially available hardware for telemetry of the data from the buoys and ships. The power and flexibility of the processor would be exploited to further reduce error in the measurements. (3) Quantify the accuracy of the basic measurements made by the sensors and of the resulting estimates of the air-sea fluxes by conducting laboratory, dock, and field calibrations and intercomparisons. (4) Deploy, on a dedicated, local surface mooring and on moorings and ships of opportunity, buoy meteorological systems and ship meteorological systems for longterm testing in order to discover and then correct problems that would, in such use, reduce the accuracy and reliability of the measurements. The work on this project includes strong scientific and technical cooperation with scientists at the University of California at San Diego and the University of Southern California. That work is supported under subcontracts. The overall project is a long lead effort of the World Ocean Circulation Experiment (WOCE).
