INCIDENT NUMBER: N/A

ATTENTION ALL SADIS USERS

SERVICE AFFECTED: WAFS SIGWX

ON 23 JANUARY, BOTH WAFCS WILL SWITCH TO SIGWX DATA PRODUCED FROM THEIR NEW AUTOMATED SIGWX SYSTEMS FOR THE 06UTC RUN ONWARDS.

SO THE SIGWX VALID 24 JANUARY 0600 UTC WILL BE THE FIRST TO INCLUDE THE CHANGES THAT ARE DISCUSSED HERE: https://www.metoffice.gov.uk/services/transport/aviation/regulated/international-aviation/wafc/upcoming-changes

THE T+24 BUFR DATA AND PNG FORMAT CHARTS WILL BE PUBLISHED APPROX 1 HOUR EARLIER THAN THEY ARE NOW, AND WILL BE LARGER IN SIZE. THEY WILL HAVE THE SAME FILE/BULLETIN NAMES AND BE PUBLISHED IN THE SAME DIRECTORIES ON SADIS AS THEY ARE NOW.

FOR THOSE USERS WHO VISUALISE THE BUFR DATA, ONCE THE CHANGE HAS TAKEN EFFECT PLEASE ENSURE THAT YOU ADJUST YOUR CHART LEGENDS TO USE "TURBULENCE (CAT + OROGRAPHIC)", ?TURBULENCE? OR JUST "TURB" INSTEAD OF CAT. PLEASE ALSO CHANGE THE UPPER LIMIT OF THE HIGH LEVEL SIGWX CHART TO FL600.

PLEASE NOTE: THE HIGH LEVEL BUFR FILES STILL INCLUDE THE VALUE FOR FL630 (19200M) AND NOT THE NEW VALUE APPROPRIATE TO FL600 TO ENSURE YOUR SYSTEMS ARE STILL ABLE TO PROCESS THE FILES.
