Official way for tower to address all aircraft on frequency for new ATIS? When there's new ATIS info available and the altimiter setting has changed, what's the official phraseology for making the announcement to all the aircraft on the frequency? I'm looking in the FAA ATC phraseology doc FAA order JO 7110.65W, but I don't see it.

My best guess would be something like "Phoenix traffic, information sierra is current, Phoenix altimiter two niner niner eight".
The tower will usually broadcast a note such as “Attention all aircraft: ATIS information Victor is now current. Wind two two zero at seven knots.  Altimeter three zero one four”.  This isn’t official phraseology and really isn’t required of ATC, but is a courtesy call to all pilots operating around the airport to retrieve the latest ATIS broadcast for reference.
