Watershed-scale Soil Moisture/Temperature and Precipitation Observatory in Qingmuguan is an important hydrological and meteorological observation node of the Chongqing Jinfo Mountain Karst Ecosystem National Observation and Research Station. The data set integrates multi-layer soil moisture and temperature of 12 stations in the observation network, as well as precipitation observation data of 8 stations. The observation station adopts the ECH2O soil moisture and temperature measurement system developed by American Meter Company, which cooperates with the Em50 data collector to realize automatic monitoring. The observation network is established in December 2019 with a sampling frequency of 15min. The monitoring depth of soil moisture andtemperature are 0-5 cm, 10 cm, 20 cm, 40 cm and 60 cm respectively. Wherein, soil moisture (volume moisture content, m3 х m-3) is measured by 5TM capacitance sensor, soil temperature (K) is measured by thermistor integrated on 5TM sensor, and precipitation (mm/15min) is measured by ECRN-100 tipping bucket rain gauge. Data is stored in Excel format.
1. File name: The soil moisture and precipitation data are stored in excel format. The file name is "QMG-Hydro_Sxxx. xlsx", where the first two digits of "xxx" represent the station number (01-12), and the third digit is optional (when it is "R", it means that the station has precipitation observation). "QMG_Hydro_station_info. xlsx" contains the longitude and latitude information of each station. Data recording time (UTC+8), soil temperature and humidity at different depths, and precipitation records are displayed in columns inside the document. The default value is - 99.
2. Data reading method: The data set is in Excel format, which can be read by common EXCEL, MATLAB and other data processing software.
