Under what condition are corrected reports not transmitted?

Corrected reports are typically not transmitted when they are superseded by a later report. In meteorological practices, once new data becomes available, it takes precedence over previous reports. The principle behind this is to ensure that users receive the most current and accurate information possible. If a new report is released, it inherently renders earlier corrections unnecessary, as the latest report will contain the updated and relevant information.

When reports are inaccurate, time-sensitive, or incomplete, they may still be transmitted with appropriate notations or follow-ups. For instance, even though a report may be flawed or time-sensitive, it still serves a purpose in communicating certain conditions or observations until better data is received. Therefore, the priority is on disseminating the newest information, emphasizing the importance of keeping meteorological records updated and relevant.
