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.
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.
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).
