The sediments from Lake Pa Kho in northern Thailand constitute a unique climatic archive since they allow recording climate and environmental changes between 60 000 and 20 000 years ago, i.e. during Marine Isotope Stage 3 and the Last Glacial Maximum. Such long terrestrial data sets are extremely rare for South East Asia and the Pa Kho record therefore not only fills an important gap, but is the first record of its kind for mainland southeast Asia.
The multi-proxy and high-resolution data set includes a lithostratigraphic description of the sediments, ¹⁴C dates, an age model, geochemistry (loss-of-ignition, bulk total organic carbon, nitrogen, sulphur and their isotopes), biomarkers and charcoal counts. The data set allows discussing the hydrological conditions in this part of the tropics during the dynamic MIS 3 period, including Sundaland's role in altering rainfall patterns.

Data description
The dataset is included in one Excel spreadsheet (xlsx) file that contains a lithostratigraphic description, all ¹⁴C dates (including dated material), an age model, LOI, TOC, TN, TC, bulk δ¹³C, δ¹⁵N, δ³⁴S; charcoal counts, and biomarkers (n-alkanes C₂₃, C₂₅, C₂₇, C₂₉, C₃₁, C₃₃ and hydrogen isotopes on C₂₃, C₂₅, C₂₇, C₂₉, C₃₁, C₃₃). See Yamoah et al. (2021) for descriptions and explanations.
The xlsx file has the following tabs:
- Read me
- Lithostratigraphy
- 14C dates
- Age-depth model
- Geochemistry
- Charcoal counts
- Biomarkers
The same data are also available in seven corresponding comma-separated values (csv) files saved with utf-8 encoding.
