ATIS (Automatic Terminal Information Service) broadcasts are updated upon receipt of any official weather, regardless of whether there's a change in the content or reported values. This means that any update to the official weather data, even if it doesn't significantly alter the operational conditions, prompts an ATIS update. This practice ensures that pilots always have the most current and accurate information available, which is crucial for safety and efficiency in flight operations.

While the other options suggest specific criteria for updating ATIS broadcasts, they do not encapsulate the comprehensive nature of ATIS updates as mandated by aviation regulations. For instance, the notion that updates are reliant on specific weather conditions or substantial changes may lead to a lapse in disseminating critical information that could impact flight safety. Therefore, the procedure of updating ATIS with any official weather report ensures pilots are informed of all pertinent information without gaps, which is vital for maintaining situational awareness during flight.
