Technician log for ICECAPS-ACE fluxtower instrumentation, at Summit Station, Greenland

This instrument log is associated with the ICECAPS instrumenation on the 15 m tower at Summit Station, Greenland. This log was completed on a daily basis by the onsite science technician. Although best efforts were made to keep the log entries consistent, there are some changes in how things were recorded over time, and between different techinicians (the technician changed roughly every ~4 months). This log contains three tabs: "Master", "Data Logging", and "Icing" Every day, the on-site technician would complete the "Data logging" and "Icing" tab noting any issues with data logging or icing for each instrument. The "master" log is not filled out on a daily basis but intented to capture details of larger unusual events that impact the data, such as raising equipment on the tower, or the operation of machinary around the instruments. Efforts have be made to propagate episodes of compromised data quality into the quality control flags in the respective datasets. The purpose of publishing this original field log is to provide additional information should questions about the published data products remain. The efforts of technicians at Summit Station and science support provided by Polar Field Services were crucial to maintaining the quality and continuity of this dataset at Summit. We acknowledge and appreciate the efforts of all the science technicians who have contributed to this log.本仪器日志关联格陵兰峰会站（Summit Station）15米塔架上的ICECAPS观测仪器（ICECAPS instrumentation）。本日志由现场科学技术员每日维护。尽管已尽力确保日志条目格式统一，但随着时间推移以及不同技术员（技术员轮换周期约为每4个月）的更换，记录方式存在一定差异。 本日志包含三个工作表标签："Master"、"Data Logging"与"Icing"。每日现场技术员需填写"Data Logging"与"Icing"标签页，记录各仪器在数据采集或结冰过程中出现的各类问题。"Master"日志无需每日填写，旨在记录影响数据质量的重大异常事件细节，例如塔架上设备的升降作业，或仪器周边机械的运行情况。 相关工作已尽力将数据质量受损的时段标记至对应数据集的质量控制标识中。发布本原始野外日志的目的，在于当已发布的数据产品存在疑问时，可为用户提供额外参考信息。 格陵兰峰会站技术员的工作以及极地野外服务公司（Polar Field Services）提供的科研支持，对维持本数据集在峰会站的质量与连续性至关重要。我们对所有为本日志作出贡献的科学技术员致以诚挚的感谢与敬意。
