Response to the letter to the editor “Is the z-score standardized RSEI suitable for time-series ecological change detection? Comment on Zheng et al. (2022)”

We would like to reiterate our initial intention that our discussion of RSEI fluctuations and the proposed RSEIz is not a denial of the value of RSEI. Indeed, we still strongly expect that RSEI will attract attention and discussion, and that it will be continuously improved to make it more applicable to planet-scale studies. Regardless, Professor Xu's work on the development of RSEI is a very visionary endeavor with great potential for application. As RSEI becomes more widely used in a variety of contexts, we also suggest that readers need to pay more attention to RSEI application matters as clarified by Professor Xu.
