2. Discussions | all | Jeremy> The RTHs shall continue there Hub role until the the full migration of WIS2 by 2030 Peter> if a NC move to to WIS2 and stop publishing data to GTS how can we make the data missing to the GTS? Remy> This is the role of the gateways. What we need is to agree on the number of gateways needed. No necessary that all RTHs run a gateway Peter> not necessary to be RTH for running a gateway. A gateway may be a part of WIS2. Before stopping the AMSS services, need to have the gateway in operation Remy> Agree, the principle is no lost of data during transition Weiquing> What do you mean by AMSS local use? Remy> In Meteo-France we use the AMSS to distribute the data and products for national use (national applications) Timo> Need to consider how WIS2 in a box can interface with the local applications. For the GBON data they can also come from the existing stations witch are already in the GTS Remy> Two separate discussions:
Kai> We need to consider a deadline for GTS leaf Hassan> In priciple 2, I think that some NCs will continue using their AMSS for their national use even if they switch to WIS2. I propose to add “stop AMMS for international use” Peter>Are all the GTS links TCP/IP? If someone is moving to WIS2 this will impact the AMSS Remy> Yes, I wonder to avoid modification on AMSS because of someone is switching to WIS2 Peter> I think if any Center is moving to WIS2, He will continue to provide data to GTS in the transition phase Weiquing> What AMSS is providing is a bulletin generation component with different information described in volume C1 Enrico> Don’t base it on volume C1. To make a good solution, we need first to understand how AMSS works, and then build a mapping to WIS2 Weiquing> I don’t say to base it on volume C1, It’s the bulletin which is based on volume C1. I think also that the transition to WIS2 is not a big bang Remy> It can be a big bang for the switch of. The WIS2 to GTS gateway is complex, I propose to trigger a discussion with the GTS experts Peter> Some countries as proposed by Hassan will continue to use the AMSS for their national applications, they can also continue to provide the data for GTS. Remy> Based on the discussions we need to asses this 2 proposals:
Weiquing> Need to distinguish between providing data and getting data. Shows example of bulletin with different messages When we move to WIS2 we need to provide notifications to the Global Services and the bulletins to the GTS Remy> What I propose as a principle is that you are not requested to provide the bulletin, some gateway will provide it Peter> We can imagine to send GTS bulletin to WIS2 Enrico> That means that the AMSS will not stop Peter> AMSS to international can stop Weiquing> If we provide bulletin and data to the global service It’s duplication Remy>the duplication in Global Cache is not a problem. the size of GTS data is not very big. But I think we need first to explore the 2 options then decide Hassan> I think to have this two parallel system is a risk of WIS2 implementation. If all NCs provide data for both GTS and WIS, may be the migration will never stop Enrico> Agree, to have a mapping WIS2 to GTS is the best solution. Let’s start to explore It and then we decide Kai> I think we can use the parallel run WIS2 and GTS with a deadline and some KPI’s to decide for the migration Remy> I propose that Experts on GTS provide some slides for next week ( Weiquing, Peter and WMO) Weiquing> I will provide my thoughts for next week |
