SST_San Blas

Sea Surface temperature monitoring at or near the former STRI field station in the San Blas Islands. Status: Inactive Locations: STRI San Blas Station, 9.552572, -78.952256 Gulf of San Blas, 9.550428, -78.946669 Contents: SST_gsah_wt_elect.csv Remote Site, 6m SST_gsbh_wt_elect.csv Remote Site, 21m SST_sbxl_wt_elect.csv Station, 1m Electronic Sea Surface Temperature recorded using Onset Hobo temperature loggers Data represent spot readings at the time stamp. File Structure: Datetime (yyyy-mm-dd HH:MM), Raw Values (C), Curated Values (C), Notes1, Notes2 Notes1 and Notes2 provide Quality Assurance information. Notes1 indicates quality of record. Possible values are: "adjusted" -> Value of datum adjusted or gap filled "bad" -> Datum failed one or more test and should not be used "doubtful" -> Datum suspect and should be used with caution "good" -> Datum accetible "missing" -> Datum missing "nc" -> Datum not yet checked Notes2 indicates the reason that a datum failed or was adjusted. Possible values are: "Calibration" -> Sensor calibration corrected "Persistence" -> Variation of data below expected range "Range" -> Datum outside of 99.9 percentile "Spike" -> Short-term increase or decrease of data significantly outside normal variance range "Gap Fill" -> Data supplied from another source Quality Assurance Proceedures: - Data are loaded into a custom-built program which premits easy visual examination of the data (including simultaneous viewing of rainfall data) - A gap-filling proceedure is carried out to fill small (<= 3 consecutive records) gaps with a simple straight line - Larger gaps (< 24 hours) are filled manually by drawing a curve that best approximates the missing data based on complete, nearby data, as well as precipitation during the gap period. This is obviously subjective, but is believed to provide quite reasonable results. - Data are visually examined for anomalies and are flagged, and adjusted when necessary, as required.本数据集为圣布拉斯群岛（San Blas Islands）前史密森尼热带研究所（Smithsonian Tropical Research Institute，简称STRI）野外工作站及其周边海域的海表温度监测数据。 数据集状态：停用 监测点位： 1. STRI圣布拉斯工作站（坐标：9.552572, -78.952256） 2. 圣布拉斯湾点位（坐标：9.550428, -78.946669） 数据集包含以下文件： - SST_gsah_wt_elect.csv：远程监测站点（水深6米） - SST_gsbh_wt_elect.csv：远程监测站点（水深21米） - SST_sbxl_wt_elect.csv：工作站监测点位（水深1米） 本次监测采用Onset Hobo温度记录仪采集电子海表温度数据，所有数据均为对应时间戳下的瞬时观测值。 数据文件字段结构如下：观测时间（格式为yyyy-mm-dd HH:MM）、原始温度值（单位：摄氏度）、校正后温度值（单位：摄氏度）、备注1、备注2。 备注1与备注2均包含质量控制相关信息： 备注1用于标记数据记录的质量等级，可选取值及含义如下： - "adjusted"：数据已完成校正或存在间隙填补操作 - "bad"：数据未通过一项或多项质量检测，不得使用 - "doubtful"：数据存疑，需谨慎使用 - "good"：数据合格，可直接使用 - "missing"：数据缺失 - "nc"：数据尚未完成质量核查 备注2用于说明数据未通过检测或被校正的具体原因，可选取值及含义如下： - "Calibration"：传感器校准修正 - "Persistence"：数据变化幅度低于预期正常范围 - "Range"：数据超出99.9百分位阈值范围 - "Spike"：数据出现显著偏离正常波动区间的短期突增或突降 - "Gap Fill"：数据间隙由外部来源补充填补 质量控制流程如下： 1. 将数据导入自主开发的专用程序，支持便捷可视化检视（可同步查看配套降雨数据）； 2. 针对连续记录条数不超过3条的小型数据间隙，采用简单线性插值法完成填补； 3. 针对时长小于24小时的较大数据间隙，结合完整的邻近时段数据及间隙时段的降水数据，通过手动绘制拟合曲线的方式填补缺失数据，该过程虽存在主观性，但可生成较为合理的插值结果； 4. 人工检视全量数据以识别异常值，根据实际需求对异常数据进行标记与必要校正。
