This manuscript released the global 5km drought indices for 1981-2022. This is a very meaningful work because it is a high-resolution dataset of drought. However, some other problems in the manuscript are still concerned in the following:

1. In Figure 5, I suggest the authors to replace (e) with North America.
2. A flow chart of generating this dataset could help the future readers.
3. More details on the method should be exposed.
4. One advantage of this dataset is high resolution. Therefore, the examples of spatial details could be shown and compared with other datasets.
5. The organization of this manuscript should be added to the end of the introduction.

The manuscript tries to develop five high-resolution (5 km) gridded drought records based on the Standardized Precipitation Evaporation Index (SPEI), which is essential and exciting for related fields. The structure of the paper is clear and the research questions are clear. However, I think the introduction part needs to improve, and more details about the development of such a field need to be described. The result and discussion should be separated and focus on the main result of the study. Besides, the structure of the result needs to improve significantly, such as in sections 3.1 to 3.3. A significant polish is needed.  Others, such as line 86-87 is it correct?

The manuscript produced global high-resolution (0.05°) and long-term (1981-2022) SPEI datasets. It is suitable for publication after a minor correction.

Line 191: Replace Table 1 with Table 2.

Line 192: Please justify the selection of a log-logistic probability distribution among others. How you attained the model parameters?

Remove the underlined sign from the values given in Table 2.
