Heating induced temperature difference measurements from SIMBA-type sea ice mass balance buoy 2019T66: 30 s after the heating cycle

Temperature and heating-induced temperature differences were measured along a chain of thermistors. SIMBA 2019T66 (a.k.a. PRIC_09_05) is an autonomous instrument that was installed on drifting sea ice in the Arctic Ocean during the 1st leg of MOSAiC in October 2019. The thermistor chain was 5 m long and included 241 sensors with a regular spacing of 2cm. The resulting time series describes the evolution of temperature and temperature differences after two heating cycles of 30 and 120 s as a function of place, depth and time between 29 October 2019 and 14 August 2020 in sample intervals of 6 hours for temperature and 24 hours for temperature differences. In addition to temperature, geographic position, barometric pressure, air temperature measured 1m over the ice level, tilt and compass were measured.

研究人员沿热敏电阻链（thermistor chain）测量了温度及加热诱导产生的温差。SIMBA 2019T66（别名PRIC_09_05）是一款自主观测仪器，于2019年10月部署在北冰洋的漂流海冰之上，隶属于MOSAiC科考计划第一航段。该热敏电阻链总长5米，共搭载241个传感器，传感器间距固定为2厘米。本数据集生成的时间序列（time series）刻画了2019年10月29日至2020年8月14日期间，经历30秒、120秒两次加热循环后，温度与温差随位置、深度及时间的演化过程；其中温度采样间隔为6小时，温差采样间隔为24小时。除温度观测外，该系统还同步采集了地理位置、大气压强、冰面上方1米处的气温、倾斜度及罗盘数据。
