Met Office MIDAS data - Message Types

It is convenient to distinguish between:

Data contained in messages and reports are structured to facilitate the extraction of selected data from the archive, the selection being based on location, time and meteorological element (where an element is a single meteorological variable such as wind speed, cloud cover or relative humidity). The tables do not store the incoming reports and data files, just the information held by them. (The tables do hold information on how the data were received i.e. met domain or message type.)

Some reports are automatically and routinely ingested into the database. Others only become available on an intermittent basis and are processed accordingly.
