<h2>Continuous along track meteorology and sea surface data,<br /> 60 minute averaged values, 1999</h2> <pre> <strong>Processed by:</strong> Richard Payne Woods Hole Oceanographic Institution Woods Hole, MA 20543 <a href=\"mailto:rpayne@whoi.edu\">rpayne@whoi.edu</a> Additional <a href=\"http://globec.whoi.edu/globec-dir/data_doc/additional_endeavor_processing_details.html\">data processing notes</a> are available. </pre> <p>The sea surface temperature as measured by the hull sensor is not shown since the sea surface temperature as measured via the engine inlet (field name is temp_ss1) is more accurate.</p> <h3>Processing Notes</h3> <ol> <li>Concatenate daily 1 minute files into one file for whole cruise</li> <li>Edit file for obvious bad data, i.e., missing data, garbage characters, etc.</li> <li>Run program which reformats data. Output parameters:<br /> Year day, lat, long, Speed made good, course made good, gyro 1 & 2, Edo speed, Edo indicator, port wind speed, starboard ws, port wind azimuth, starboard waz, air temp, relative humidity, barometric pressure, sea surface temp @5m & 1m depth, Edo depth, Chirp sonar depth.</li> <li>Put plots of all parameters on screen and look for obvious single bad points. Edit in basic concatenated file. Except I have not edited depths.</li> <li>Iterate steps 2-4 until no more obvious bad points.</li> <li>Run second program which computes true wind speed and direction from speed and course made good, gyros, larger of port or starboard ws and accompanying wind azimuth. Outputs are year day, lat lon, speed and course made good, gyro, relative ws and direction, true ws and direction, air temp, relative humidity, barometric pressure, short- and long-wave radiation,5m and 1m sea surface temps, Edo depth, Chirp sonar depth, Edo speed, Edo indicator.</li> <li>Check plots of true wind speed and direction to make sure they look ok.</li> <li>Run vector averaging program which produces 60 minute series. The program uses 60 consecutive records and does not check for missing records. I have not carried depths since hourly averages do not seem useful nor Edo speeds since they seem pretty generally useless. Output parameters are: Year day, lat, long, true wind speed and direction, air temp, relative humidity, barometric pressure, short- and long-wave radiation, sea surface temp @ 5m & 1m.</li> </ol> <p><em>From: Richard E.

<h2>沿航迹连续气象及海面观测数据集，1999年60分钟平均值</h2> <pre> <strong>数据处理：</strong> Richard Payne 伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution） 美国马萨诸塞州伍兹霍尔，邮编20543 <a href="mailto:rpayne@whoi.edu">rpayne@whoi.edu</a> 可获取更多<a href="http://globec.whoi.edu/globec-dir/data_doc/additional_endeavor_processing_details.html">数据处理说明</a>。 </pre> <p>由于通过发动机进气口测量的海表温度（字段名为temp_ss1）精度更高，因此未展示船体传感器测得的海表温度。</p> <h3>处理说明</h3> <ol> <li>将每日1分钟分辨率文件拼接为完整航次的单文件</li> <li>对文件中明显的异常数据（如缺失值、乱码等）进行编辑修正</li> <li>运行数据格式化程序，输出参数包括：年积日、纬度、经度、对地航速、对地航向、陀螺仪1及2、Edo测速数据、Edo状态指示器、左舷风速、右舷风速（ws为wind speed缩写）、左舷风方位角、右舷风方位角（waz为wind azimuth缩写）、空气温度、相对湿度、大气压力、5米及1米水深海表温度、Edo测深数据、Chirp声呐（Chirp sonar）测深数据</li> <li>将所有参数的绘图展示于界面，排查单个明显异常点，并在基础拼接文件中进行修正；但未对测深数据进行编辑</li> <li>重复步骤2至4，直至无明显异常点</li> <li>运行第二个程序，基于对地航速、对地航向、陀螺仪数据、左右舷风速的较大值及对应风方位角计算真实风速与风向。输出参数包括：年积日、经纬度、对地航速与航向、陀螺仪数据、相对风速及风向、真实风速及风向、空气温度、相对湿度、大气压力、短波与长波辐射、5米及1米水深海表温度、Edo测深数据、Chirp声呐测深数据、Edo测速数据、Edo状态指示器</li> <li>查看真实风速与风向的绘图，确认结果合理</li> <li>运行矢量平均程序以生成60分钟序列数据：该程序会将60条连续记录进行平均，且未检查缺失记录。由于小时平均测深数据实用性较低，且Edo测速数据整体可用性较差，因此未纳入平均计算。输出参数包括：年积日、纬度、经度、真实风速及风向、空气温度、相对湿度、大气压力、短波与长波辐射、5米及1米水深海表温度</li> </ol> <p><em>文档来源：Richard E.
