<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>

<p><strong>Processing Notes</strong></p>

<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>

<p>由于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，因此未展示船体传感器测得的海表温度。</p>

<p><strong>处理说明</strong></p>

<ol>
<li>将每日1分钟分辨率数据文件拼接为单次完整航次的单一文件</li>
<li>对文件进行初步清洗，剔除明显无效数据（如缺失值、乱码等）</li>
<li>运行数据格式重构程序，输出参数包括：年积日、纬度、经度、对地航速、对地航向、陀螺罗经1与2、Edo测速仪航速、Edo状态指示器、左舷风速、右舷风速、左舷风方位角、右舷风方位角、气温、相对湿度、气压、5米与1米深度海表温度、Edo测深仪水深、声纳测深。</li>
<li>将所有参数绘制成图表并在屏幕上展示，排查明显的单点异常值，对基础拼接文件进行编辑；但本次未对水深数据进行清洗。</li>
<li>重复步骤2至4，直至无明显异常数据。</li>
<li>运行第二套程序，基于对地航速、对地航向、陀螺罗经数据、左右舷风速较大值及对应风方位角计算真风速与真风向。输出参数包括：年积日、纬度、经度、对地航速与对地航向、陀螺罗经数据、相对风速与风向、真风速与真风向、气温、相对湿度、气压、短波与长波辐射、5米与1米深度海表温度、Edo测深仪水深、声纳测深、Edo测速仪航速、Edo状态指示器。</li>
<li>查看真风速与真风向的绘图结果，确认数据合理性。</li>
<li>运行矢量平均程序生成60分钟分辨率序列数据：该程序会对连续60条记录进行平均处理，未对缺失记录进行校验。本次未输出水深数据（因小时平均水深数据实用性较低），也未输出Edo测速仪航速数据（因该数据普遍可用性较差）。输出参数包括：年积日、纬度、经度、真风速与真风向、气温、相对湿度、气压、短波与长波辐射、5米与1米深度海表温度。</li>
