River Habitat Surveys, 1994 - provision of map information and initial analysis

[摘要] During the SWALES experiment in the autumn of 1993, the Sonic Buoy was deployed twice as part of an array of moored instrumentation. On the Sonic Buoy, 3 component wind speed samples were acqujred by the Sonic Processor from a Gill Sonic Anemometer; using a sampling rate of 20.83 Hz. These data were spectrally processed to a form which allowed estimation of wind stress to be made, using the disSipation technique. The processed data were saved to an EPROM logger and a selected set of parameters was also sent to the Formatter Processor for amalgamation with the Multimet mean meteorological data. Raw anemometer data were continuously telemetered via a VHF link to shore and occasional records of raw data were also logged on the Sonic Buoy Raw Data Logger. This data report briefly describes the processes employed in acquisition of the data. It then describes the processes for the recovery of the data from the various source media, the quality control procedures applied and, finally, the resulting output data files. Appendices include comprehensive details of the software developed for the above processes and of the formats used for the input and output data.
