CONDUCTIVITY, WIND DIRECTION, SHORTWAVE IRRADIANCE, AIR TEMPERATURE and other underway - surface data collected in the North Atlantic Ocean on the OCEANUS cruises OC317, OC319 and others as part of the GB project from 1998-02-07 to 1998-12-14 (NODC Accession 0105689)

NODC Accession 0105689 includes underway - surface, meteorological, chemical, physical and optical data collected aboard the OCEANUS during cruises OC317, OC319, OC321, OC322, OC331, OC332, OC333 and OC334 in the North Atlantic Ocean from 1998-02-07 to 1998-12-14. These data include CONDUCTIVITY, WIND DIRECTION, SHORTWAVE IRRADIANCE, AIR TEMPERATURE, WIND SPEED, LONGWAVE IRRADIANCE, SALINITY - SURFACE WATER, RELATIVE HUMIDITY, PRECIPITATION, BAROMETRIC PRESSURE and SEA SURFACE TEMPERATURE. The instruments used to collect these data include thermosalinographs. These data were collected by Richard Payne of Woods Hole Oceanographic Institution as part of GB. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-04-13.

data processing notes (http://globec.whoi.edu/globec-dir/data_doc/additional_endeavor_processing_details.html) are available.

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.
Processing Notes

Concatenate daily 1 minute files into one file for whole cruise
Edit file for obvious bad data, i.e., missing data, garbage characters, etc.
Run program which reformats data. Output parameters:
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.
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.
Iterate steps 2-4 until no more obvious bad points.
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.
Check plots of true wind speed and direction to make sure they look ok.
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.

国家海洋数据中心（National Oceanographic Data Center，NODC）收录号0105689包含1998年2月7日至1998年12月14日期间，在北大西洋海域搭乘"OCEANUS"号科考船，于航次OC317、OC319、OC321、OC322、OC331、OC332、OC333及OC334中采集的走航表层、气象、化学、物理及光学观测数据。此类数据涵盖电导率、风向、短波辐照度、气温、风速、长波辐照度、表层海水盐度、相对湿度、降水量、气压及海表温度。采集上述数据所用仪器包括温盐测量仪（thermosalinograph）。该数据集由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution，WHOI）的理查德·佩恩作为GB项目的一部分完成采集，并由生物与化学海洋学数据管理办公室（Biological and Chemical Oceanography Data Management Office，BCO-DMO）于2013年4月13日提交至NODC。

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。

处理说明
1. 将单航次每日的1分钟分辨率数据文件合并为单个总文件。
2. 对明显的不良数据（如缺失值、乱码等）进行文件编辑。
3. 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、陀螺罗经1与2、Edo测速仪航速、Edo测速仪状态标识、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米与1米深度处海表温度、Edo测速仪水深、Chirp声呐水深。
4. 将所有参数的绘图展示于屏幕，排查明显的单点异常值，并在基础合并文件中进行编辑，唯独未对水深数据进行编辑。
5. 重复执行步骤2至4，直至无明显异常数据点。
6. 运行第二个程序，基于对地航速、对地航向、陀螺罗经数据、左右舷风速中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、陀螺罗经数据、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米与1米深度海表温度、Edo测速仪水深、Chirp声呐水深、Edo测速仪航速及状态标识。
7. 检查真实风速与风向的绘图结果，确保数据合理。
8. 运行矢量平均程序以生成60分钟分辨率的序列数据。该程序使用连续60条记录进行平均，且不检查缺失记录。由于小时平均水深数据实用性较低，且Edo测速仪航速数据整体可用性较差，因此未纳入平均计算。最终输出参数包括：年积日、经纬度、真实风速与风向、气温、相对湿度、气压、短波与长波辐射、5米与1米深度海表温度。
