CONDUCTIVITY, WIND DIRECTION, SHORTWAVE IRRADIANCE, AIR TEMPERATURE and other underway - surface data collected in the North Atlantic Ocean on the ENDEAVOR and OCEANUS cruises EN319, EN320 and others as part of the GB project from 1999-02-11 to 1999-12-14 (NODC Accession 0104427)

NODC Accession 0104427 includes underway - surface, meteorological, physical, chemical and optical data collected aboard the ENDEAVOR and OCEANUS during cruises EN319, EN320, EN321, EN322, EN323, EN324, EN325, EN330, EN331, OC336, OC338, OC339, OC340, OC341, OC342, OC343, OC344, OC345, OC346 and OC347 in the North Atlantic Ocean from 1999-02-11 to 1999-12-14. These data include CONDUCTIVITY, WIND DIRECTION, SHORTWAVE IRRADIANCE, AIR TEMPERATURE, WIND SPEED, LONGWAVE IRRADIANCE, RELATIVE HUMIDITY, SALINITY - SURFACE WATER, BAROMETRIC PRESSURE, PRECIPITATION 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.

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）存档编号0104427包含1999年2月11日至1999年12月14日期间，在北大西洋海域由ENDEAVOR号与OCEANUS号科考船执行航次EN319、EN320、EN321、EN322、EN323、EN324、EN325、EN330、EN331、OC336、OC338、OC339、OC340、OC341、OC342、OC343、OC344、OC345、OC346及OC347时采集的走航表层、气象、物理、化学及光学观测数据。该数据集包含电导率、风向、短波辐照度、气温、风速、长波辐照度、相对湿度、表层海水盐度、大气压力、降水量及海表温度。采集所用设备包括温盐仪（thermosalinographs）。上述数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution）的理查德·佩恩作为GB项目的一部分采集，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日将这些数据提交至NODC存档。

注：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，因此船体传感器测得的海表温度未纳入本数据集。

数据处理笔记：
1. 将每日1分钟粒度的原始文件拼接为单航次完整数据文件
2. 对文件进行编辑，剔除明显的无效数据（如缺失值、乱码等）
3. 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及2、Edo航速、Edo状态标识、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、大气压力、5米及1米水深海表温度、Edo测深、声呐测深
4. 将所有参数的绘图结果可视化展示，排查并编辑明显的单点异常值，未对深度数据进行编辑
5. 重复步骤2至4，直至无明显异常数据
6. 运行第二套数据处理程序，基于对地航速与航向、陀螺罗经数据、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、对地航速与航向、陀螺罗经数据、相对风速与风向、真风速与风向、气温、相对湿度、大气压力、短波与长波辐射、5米及1米海表温度、Edo测深、声呐测深、Edo航速、Edo状态标识
7. 检查真风速与风向的绘图结果，确保数据合理
8. 运行矢量平均程序生成60分钟时间序列数据：该程序使用连续60条记录进行平均计算，未校验缺失记录。由于小时平均深度数据实用性较低，且Edo航速普遍无参考价值，故未纳入深度与Edo航速数据。输出参数包括：年积日、纬度、经度、真风速与风向、气温、相对湿度、大气压力、短波与长波辐射、5米及1米海表温度。
