Dear Anna of WMO and TT-AvData team,

Sorry for the delay in our response. (Yesterday, we were on National Holiday for physical fitness day.) JMA has some comments on this new IWXXM version. Regarding QVA, we would like to have some items in this IWXXM version to describe Volcanic Ash Advisory. Particularly, we think we need to add items of "Remarks", "ERUPTION DETAILS" and "NEXT ADVISORY" and so on.

We would appreciate it if you could give us about next step.

Best regards Yori

Hi Paula,

Assuming the future phasing out of VAA, the role of QVA remarks would be similar to that of VAA. Then, the idea for an example would be the same as the one for VAA:

LATEST REP FM KVERT (0120Z) INDICATES ERUPTION HAS CEASED.
TWO DISPERSING VA CLD ARE EVIDENT ON SATELLITE IMAGERY

I have another idea that the remarks could contain uncertainty in the calculation. This was suggested in QVA workflow discussion as specific remarks for QVA. Could anyone provide an example of this?

Best regards, Akira
