SWOT 2019-2020 Prelaunch Oceanography Field Campaign SIO Pressure-sensing Inverted Echo Sounder (PIES)

This dataset provides the in-situ measurements from a Pressure-sensing Inverted Echo Sounder (PIES) deployed by the SWOT prelaunch field campaign. The campaign was designed to test the performance of several instruments/platforms in meeting the SWOT Calibration/Validation (CalVal) requirement. It was conducted near the SWOT CalVal crossover location, about 300 kilometers west of Monterey, California between September, 2019 and January, 2020. The campaign also deployed three CTD moorings, a slocum glider, and another bottom pressure recorder. The PIES measurements include bottom pressure and the round-trip travel time from the IES, which can be used to derive equivalent steric height through regression. Details can be found in the user guide and the journal reference given in the documentation section.

本数据集提供了由SWOT发射前野外试验部署的压力感应倒置回声测深仪（Pressure-sensing Inverted Echo Sounder, PIES）的原位测量数据。该试验旨在验证多款仪器/平台是否满足SWOT定标与验证（Calibration/Validation, CalVal）需求，于2019年9月至2020年1月期间，在加利福尼亚州蒙特雷以西约300公里的SWOT定标验证交汇点附近开展。本次试验还部署了3台温盐深（CTD）锚系设备、1台Slocum滑翔机以及另一台海底压力记录仪。PIES的测量数据包含海底压力与该倒置回声测深仪的往返传播时间，可通过回归分析推导得到等效比容高度。详细信息可参阅文档章节中给出的用户指南与期刊参考文献。
