This question already has an answer here:
Recently, I submitted a paper to a journal published by Elsevier. The "Elsevier Journal Finder" feature suggested this particular journal in #3 out of a total of 5 suggestions. A while ago, I had also published a work in the same journal, which was of the same topic (satellite retrievals) that I was trying to submit now. However, for the recent submission, the editor decided that the paper is not topical to the journal and suggested to submit in a mathematical journal. Although there are some mathematical applications in this paper, they are not new, has been known for over 20 years, and was only applied towards satellite retrievals. I am a bit puzzled. Any advice will be appreciated.
