GTS, SEAS, keyed, VOSClim And GCC Marine Surface Data from NCDC and NOCS

Marine surface data (ship observation, moored buoys, etc) are segregated from the GTS data stream at NCDC. The GTS records are encoded into IMMA format and collected into monthly files. The primary use of these data are input and cross-check referencing with other ICOADS data sources.

海洋表面数据（包括船舶观测、系留浮标等）在NCDC处被从GTS数据流中分离。GTS记录被编码为IMMA格式，并按月收集成文件。这些数据的主要用途是与其他ICOADS数据源进行输入和交叉核对参考。
