After a year or so of trying to get this published, my colleague finally succeeded – which is good news for me since I’m the second author (I built the software the research is based on).
Now I just have to start publishing some first authorship papers.
Edit: Booyah! The same day I write this post I get a response on my phenology modelling paper where I’m first author. The reviewers comments are just minor fixes to my writing – so once I’ve made the changes, I’ve got a paper. This makes me very happy. Although I’ll still be cautious until the paper is actually in print.
