Data on the Seawater and Atmospheric Temperature Recorded by Data Logger at Katsuura, Pacific Coast of Japan

This dataset contains seawater and atmospheric temperature data recorded by data logger from 2010 to 2020 at five locations of Katsuura, Pacific coast of Japan. See locations.csv file for the five locations.<br>The "original data" folder contains five folders that contain original data files of temperature recorded by data logger at each location. The first line of the original data file contains the unique number of data (#), measurement date and time (Time, GMT + 9: 00), and water temperature in degree Celsius (Temp) up to the third decimal place. Each data recorded at 15–30-minute intervals is lined up below the first line.<br>The "daily data" folder contains daily data files of the five locations. The daily mean, maximum, and minimum temperature were calculated using the original temperature data. The file containing these temperature data was defined as the daily temperature data file (Table 3). In the first line of the daily data file, the month (Month), date (Date), daily maximum temperature (20xx max), daily minimum temperature (20xx min), and daily mean temperature (20xx ave) are listed, where “xx” refers to the last two digits of the year of data acquisition. In the month and day columns, 366 rows of numbers corresponding to January 1st to December 31st are lined up, and temperature data for each year (20xx) are next to them.See detail for Kawase (2021).<br>Kawase, H. 2021.

本数据集包含2010年至2020年间，由数据记录仪（data logger）在日本太平洋沿岸胜浦市5个监测点位采集的海水与大气温度数据。5个监测点位的详细信息请参见locations.csv文件。
“原始数据”文件夹内含5个子文件夹，分别存储对应点位的数据记录仪采集的原始温度数据文件。每份原始数据文件的首行包含数据唯一编号（#）、测量日期与时间（Time，GMT+9:00）以及精确至小数点后三位的摄氏度水温（Temp）；首行下方按序排列每15至30分钟采集的单条数据。
“日度数据”文件夹内含5个点位的日度数据文件。日平均温、日最高温与日最低温均由原始温度数据计算得到，存储此类温度数据的文件被定义为日度温度数据文件（见表3）。日度数据文件的首行依次列出月份（Month）、日期（Date）、日最高温（20xx max）、日最低温（20xx min）与日平均温（20xx ave），其中“xx”代表数据采集年份的后两位数字。月份与日期列共包含366行数据，对应1月1日至12月31日，其后依次标注各年份（20xx）对应的温度数据。详细信息可参考Kawase（2021）的研究。
