Sequence database of the lake core sporopollen spectrum and temperature/precipitation reconstruction of Yamdrog Yumtso, southern Tibetan Plateau (0-20kaBP)- A Big Earth Data Platform for Three Poles

This dataset contains data on the lake core sporopollen spectrum and temperature/precipitation reconstruction sequence of Yamdrog Yumtso Lake in the southern Tibetan Plateau. It is used to study the environmental changes in the Yamdrog Yumtso region by 20 ka. It is obtained by the sporopollen analysis method. This data set is obtained by laboratory measurement and calculation. The samples and data are collected and identified in strict accordance with relevant operating procedures at all stages.

There are three subtables in this dataset.

The first two tables comprise the following analysis data of TC1 pore sporopollen samples.

Field 1: Sample Number

Field 2: Sample Depth Unit: cm

Field 3: Sample Age Unit: aBP

Field 4: Total sporopollen concentration Units: granules/gram

Field 5: Total Pollen Granules Unit: Number of grains

Field 6: Total number of indicative pollen Unit: Number of grains

Field 7: Identification of indicative pollen number Unit: Number of grains

Field 8: Sample Weight Unit: Grams

Field 9: Concentration Coefficient Units: granules / gram

Field 1: Sample Number

Field 2: Plant species

Field 3: Pollen content Unit: %

The third subtable is the reconstructed temperature precipitation and has 6 fields.

Field 1: Sample Code

Field 2: Sample Name

Field 3: Depth Unit: cm

Field 4: Age Unit: aBP

Field 5: Average annual temperature Unit: 0.1 °C

Field 6: Annual precipitation Unit: 0.1 mm

The rock core was collected from the Yamdrog Yumtso Basin in the southern part of the Tibetan Plateau. The approximate sampling location is 90°27′E，28°56′N, and the altitude there is 4425 m.
