<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>
</ol>

<p>Specific notes:</p>

<p>The data quality is generally pretty poor on the Oceanus cruises. OC297 and OC298 have no SOG, COG,or gyro so I could not correct the winds. I almost set the TWS, TWD to 0 but decided to leave them in as RWS, RWD. One could get a semiqualitative feel for the winds. OC301 had gyro but no SOG, COG so I computed them from the GPS position differences. It came out better than I expected. Warn users to be skeptical about the Oceanus data.</p>

<p>船体传感器测得的海表温度未予展示，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分钟采样文件拼接为单次巡航的完整单文件</li>
<li>对文件中明显的无效数据进行编辑修正，例如缺失数据、乱码字符等</li>
<li>运行程序对数据进行格式重构，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与2、Edo测速仪速度、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、空气温度、相对湿度、大气压力、5米与1米深度海表温度、Edo测深数据、声纳测深数据。</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，并在拼接后的基础文件中进行编辑修正（注：深度数据未做编辑）。</li>
<li>重复步骤2至4，直至无明显异常点。</li>
<li>运行第二套程序，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，计算真风速与真风向。输出参数包括：年积日、经纬度、对地航速与对地航向、陀螺仪数据、相对风速与风向、真风速与真风向、空气温度、相对湿度、大气压力、短波与长波辐射、5米与1米深度海表温度、Edo测深数据、声纳测深数据、Edo测速仪速度、Edo状态指示器。</li>
<li>检查真风速与真风向的绘图结果，确保结果合理。</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条记录生成数据，未对缺失记录进行校验。因小时平均数据并无实用价值，且Edo测速仪速度整体可用性较低，故未保留深度数据与Edo测速仪速度。输出参数包括：年积日、纬度、经度、真风速与真风向、空气温度、相对湿度、大气压力、短波与长波辐射、5米与1米深度海表温度。</li>
</ol>

<p>特别说明：</p>

<p>Oceanus号巡航所获数据的整体质量普遍较差。OC297与OC298航次未记录对地航速、对地航向及陀螺仪数据，因此无法对风速风向进行校正。本可将真风速、真风向设为0，但最终决定保留数据并以相对风速、相对风向形式呈现，使用者仍可对风速情况获得半定性的参考。OC301航次配备陀螺仪，但未记录对地航速与对地航向，因此通过全球定位系统（Global Positioning System, GPS）的位置差计算得到上述参数，效果好于预期。请提醒使用者对Oceanus号航次的数据保持审慎态度。</p>
