<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 &amp; 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 &amp; 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 &amp; 1m.</li>

## 沿航迹连续气象与海面数据：1998年60分钟平均数据集

<p>船体传感器测得的海表温度未纳入本数据集，因通过发动机进气口测得的海表温度（字段名为temp_ss1）精度更高。</p>

<h3>处理说明</h3>

<ol>
<li>将每日1分钟粒度的文件拼接为完整航次单文件</li>
<li>清理文件中明显的无效数据，例如缺失值、乱码等</li>
<li>运行程序进行数据格式重构，输出参数包括：年积日（Year day）、纬度、经度、对地航速（Speed made good）、对地航向（Course made good）、陀螺仪1与2数据、Edo测速仪航速（Edo speed）、Edo状态指示器数据、左舷风速、右舷风速、左舷风向方位、右舷风向方位、气温、相对湿度、气压、5米及1米水深海表温度、Edo测深值、声呐测深值（Chirp sonar depth）。</li>
<li>将所有参数的绘图展示于界面，排查明显的单点异常值，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>重复执行步骤2至4，直至无明显异常值残留。</li>
<li>运行第二套程序，基于对地航速与航向、陀螺仪数据、左右舷风速的较大值及对应风向方位，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、相对风速与风向、真实风速与风向、气温、相对湿度、气压、短波与长波辐射、5米及1米水深海表温度、Edo测深值、声呐测深值、Edo测速仪航速、Edo状态指示器数据。</li>
<li>查看真实风速与风向的绘图结果，确认数据合理性。</li>
<li>运行矢量平均程序生成60分钟时序数据集：该程序对连续60条记录进行平均计算，且未对缺失记录进行校验。因小时平均测深数据实用性较低，且Edo测速仪航速整体可用性较差，故未纳入本次平均结果。最终输出参数包括：年积日、纬度、经度、真实风速与风向、气温、相对湿度、气压、短波与长波辐射、5米及1米水深海表温度。</li>
