Temperature measurements from SIMBA-type sea ice mass balance buoy 2016T44

Temperature and heating-induced temperature difference profiles were measured through the atmosphere, sea ice, and ocean using a SIMBA-type sea ice mass balance buoy equipped with a several meter long thermistor chain. The present dataset was recorded by SIMBA 2016T44 (original name FMI_05) installed on drifting sea ice in the Arctic Ocean during the expedition Polarstern PS101 (ARK30/3,KarasikSeamount) in 2016. Data is available between 2016-09-15 22:00:00 and 2017-02-18 14:55:00. The thermistor chain was Variable 5 m long and included 240 sensors with a regular spacing of 2 cm. The resulting time series includes the evolution of temperature and temperature differences at 30 s and 120 s during a heating cycle of 120 s as a function of location, depth and time. The sampling intervals were usually between hourly and daily, but were most frequently configured to 6 hours for temperature, and 24 hours for temperature differences. In addition to temperatures and geographic location were measured. The present dataset was processed as follows: obvious inconsistencies (missing values) and unrealistic values of GPS position have been removed. This instrument was deployed as part of the project project FMI.

本数据集采用搭载有数米长热敏电阻链的SIMBA型海冰质量平衡浮标，在大气、海冰与海洋环境中采集了温度及加热诱导温度差廓线。本次数据集由部署于北冰洋漂流海冰上的SIMBA 2016T44浮标（原名称为FMI_05）采集获取，该浮标搭载于2016年的极地号（Polarstern）PS101科考航次（ARK30/3，卡拉西克海山）中。数据集的时间覆盖范围为2016年9月15日22:00:00至2017年2月18日14:55:00。该热敏电阻链为可变型，总长5米，包含240个传感器，传感器间距固定为2厘米。所得时间序列记录了温度与温度差的演化过程：在120秒的加热周期内，于第30秒和第120秒进行采样，数据随位置、深度及时间变化。采样间隔通常在每小时至每日之间，其中温度数据的采样间隔多设置为6小时，温度差数据的采样间隔多设置为24小时。除温度外，数据集同时记录了地理定位信息。本数据集已进行如下预处理：剔除了明显的不一致数据（缺失值）以及不符合实际的GPS定位异常值。本仪器作为FMI项目的组成部分完成部署。
