<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量的海面温度（字段名为temp_ss1）精度更高，因此未展示船体传感器测得的海面温度。</p>

<p><strong>处理说明</strong></p>

<ol>
<li>将每日1分钟采样文件拼接为单次航次的完整数据文件</li>
<li>编辑文件以剔除明显的异常数据，例如缺失数据、乱码字符等</li>
<li>运行数据格式化程序，输出参数包括：<br>年积日、纬度、经度、对地航速、对地航向、陀螺1与陀螺2、Edo航速、Edo指示器、左舷风速、右舷风速、左舷风向方位角、右舷风向方位角、气温、相对湿度、大气压力、5米与1米深度处海面温度、Edo测深、Chirp声呐测深</li>
<li>将所有参数的绘图展示于屏幕，排查明显的单点异常值，并在基础拼接文件中进行编辑。注：未对测深数据进行编辑</li>
<li>重复执行步骤2至4，直至无明显异常数据</li>
<li>运行第二套程序，基于对地航速、对地航向、陀螺数据、左右舷风速的较大值及对应风向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、陀螺数据、相对风速与风向、真实风速与风向、气温、相对湿度、大气压力、短波与长波辐射、5米及1米海面温度、Edo测深、Chirp声呐测深、Edo航速、Edo指示器</li>
<li>检查真实风速与风向的绘图结果，确保数据合理</li>
<li>运行矢量平均程序生成60分钟序列数据。该程序使用连续60条记录，未对缺失记录进行校验。由于小时平均数据实用性较低，且Edo航速普遍可用性较差，因此未保留测深与Edo航速数据。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、大气压力、短波与长波辐射、5米及1米海面温度</li>
