Network of soil temperature and moisture on the Pali (2015-2021)- A Big Earth Data Platform for Three Poles

The soil temperature and moisture observation network is located south of Tibetan Plateau, with an average elevation of 4,486 meters, providing soil moisture, soil temperature and freeze-thaw measured datasets.

Data content (data file, table name, and observation indicators included) :

(1) Number of sites: 25 observation sites

(2) observation variables: (soil moisture and soil temperature)

(3) Observation depths: (0-5, 10, 20 and 40 cm)

(4) Geographic coverage: 27.7°-28.1°N； 89.1°-89.4°E

(5) Spatial resolution: passive microwave satellite pixel (0.3°)

(6) Temporal resolution: 30 min resolution

(7) Soil moisture measurement accuracy and resolution: ± 2% VWC and 0.1% VWC.

Data content field description:

(1) Variable 1-6: Date (Integer: yyyy-mm-dd-hh-mm-ss; UTC+8)

(2) Variable 7-34: Observational data values at each site (real, missing value: -99.00)

(3) Soil moisture(SM): %vol（m³/m³)

(4) Soil temperature(ST): ℃

Data correction and quality control:

The 30 min resolution temperature data are the direct sampling data after quality control, and the soil moisture volume content is the correction value based on the soil moisture measurement by the drying method.

File naming and required software

For example: "SM_PL-30 minutes-05 cm.txt", "ST_PL-30 minutes-05 cm.txt"

SM refers to soil moisture, ST refers to soil temperature, PL refers to Pali, 30 minutes refers to the temporal resolution of data, and 05 cm refers to the depth of the sampled soil layer.
