[ 海洋 ] --- 普里兹湾水域的CTD 和 XCTD的精度

自用:



印度洋南端,普里兹湾水域的 CTD 和 XCTD的精度范围


-------------------------------------------

CTD:

    The manufacturer's specifications for accuracy of CTD are 0.01°C in temperature and 0.01 mS/cm in conductivity, leading to a salinity error less than 0.015 psu.The temperature and conductivity sensors of CTD are calibrated by the manufacturer every year.

翻译:  

    生产商说明的CTD的精确度: 温度上为0.01℃ ,电导率上为 0.01 mS/cm。盐度错误少于0.015psu。并且CTD上温度和电导率的传感器,生产商每年都会修正。



-------------------------------------------

XCTD: 

     The manufacturer's specified accuracy of XCTD temperature and conductivity is 0.02°C and 0.03 mS/cm, respectively. The accuracy of XCTD salinity is accordingly expected to be about 0.04 psu within the temperature range in this study area (typically 1° to –2°C). 

翻译:

    生产商说明的XCTD的精度:温度上0.02℃,电导率上0.03 mS/cm。而在盐度上,根据该研究区域的温度范围(-2℃-1℃)则需要0.04 psu的精确度。



--------------------------------------------


总结,CTD和XCTD 对于温度和电导率的测量没啥问题,最大的问题是盐度的检测。

盐度精确度范围 和研究区域的实际温度范围有关。
