Transmissometer dataset with Quality Control (Ctg Alphatracka II @ 1 sample / hour) from INGV/GEOSTAR - SN-3 seafloor platform during ORION-GEOSTAR3 project in Southern Tyrrhenian Sea site (Marsili Basin), part of ORION network

Alphatracka II is a transmissometer that measures the beam attenuation coefficient at 660 nm.
This Quality Controlled (QC) version of the datasets has been elaborated verifying sensor efficiency through post-calibration and standardized validation procedures. More information about QC procedures is contained in the download file.

Alphatracka II是一款可在660纳米波长下测量光束衰减系数的透射仪(transmissometer)。
本数据集的质量控制(Quality Controlled, QC)版本系经精细化处理编制而成，编制过程中通过事后校准与标准化验证流程验证了传感器效能。有关质量控制流程的更多详细信息已收录于下载文件中。
