1. The total number is the unified number of the survey year, such as 17-001 (the first survey point in 2017), and the field number is the single field number.

2. Time: Beijing time at the time of measurement, such as: 13:25, August 1, 2017 (13:25, August 1, 2017).

3. Geographical location: the longitude and latitude of the measuring point, such as 29.6584101.0884 (29.6584 ° n, 101.0884 ° E), which is measured by Garmin 63sc GPS in the field.

4. Altitude: the absolute altitude of the measuring point, such as 4500m (4500m above sea level), is measured by Garmin 63sc GPS in the field with an accuracy of 1m.

5. Measured vegetation coverage (%): measured in the field with quadrat (1000 m * 1000 m).

6. Atmospheric pressure: measured by dph-103 intelligent digital temperature and humidity barometer in the field, such as 651.7kpa, accuracy: 0.1 kPa.

7. Air temperature: measured by dph-103 intelligent digital temperature, humidity and barometer in the field, such as 15.61 ℃, accuracy: 0.01 ℃.

8. Relative humidity: measured by dph-103 intelligent digital temperature, humidity and barometer in the field, such as 79.1%, accuracy: 0.1%.

9. Relative oxygen content: measured by td400-sh-o2 portable oxygen detector in the field, such as 20.16%, accuracy: 0.01%.

Among them, the altitude of sampling points 17-001 to 17-065 is measured by Garmin Oregon 450 GPS with an accuracy of 1 m; The atmospheric pressure is measured by Casio prg-130gc barometer with an accuracy of 5 HPA; The relative oxygen content is measured by cy-12c digital oxygen meter, with a range of 0-50.0%, a resolution of 0.1% and an accuracy of ± 1%.

File naming and required software

The data is in Excel format, "12 oxygen content data - Qinghai Tibet Plateau. Xlsx" is the field measurement data. "13 - oxygen content data - Namuco station and other stations" is the site data, where the file name is "xxxxxxnumber. Xlsx", where XXXX represents the site name and number represents different oxygen meters, such as ali1 Xlsx represents the data of the first oxygen meter in Ali station.
