Quoting Michael Wouters: "According to this, http://www.nist.gov/manuscript-publication-search.cfm?pub_id=912449
there are many practical challenges with a one way free-space optical link." That paper indicates that one way transfer with noise of a few picosec should be feasible using an IR laser. Especially if only required at night for synchronisation of the timebases of the various telescope/detectors in a stellar intensity interferometer. Atmospheric scintillation should be lower as well as background noise from the sky, sun etc. The other factors like rain, hail, snow, fog etc aren't an issue as these preclude observation of the stars of interest.
