Performance of the Antarctic Observing Network (AntON) SYNOP

Surface stations

This chart shows the status of SYNOP messages for the main hours on the GTS during 2018, with green representing good performance, light green representing less than 90% of expected messages (acceptable, but not adequate for CLIMAT), yellow less than 80% and amber less than 50%.

If less that 30% are found then the number of days in the month that observations were recieved is displayed which may have been on non main synoptic hours which occurs mainly for AWS transmitting via Argos.

When the number of days is displayed a D is shown before the number, greater than 25 days is displayed in green, light green for between 20 and 25 days, yellow for between 10 and 20 days, amber for between 5 and 10 days and red for less than 5 days.
