Port Meteorological Officers (PMOs) support observing programs aboard Voluntary Observing Ships. They are responsible for recruitment of new vessels as observers, and also for ensuring the quality of observations from vessels actively participating in the program. PMOs spend a major part of their time visiting ships, primarily assisting deck officers with marine weather observation practices, weather codes, and report transmission procedures. They distribute observing forms, handbooks, and operating instructions, in addition they also calibrate some of the weather instrumentation. The PMO will review completed observation forms on board, point out omissions or errors, and suggest methods for improvement. They maintain contact with ship owners and agents, port operators, shore radio stations, and maritime academies to secure the cooperation of the maritime community.
