That along with some of the objectives we set at last AGG/AOPC meeting (which I am still working on) and some offers we received from PR's at Congress. I think it should be a good discussion and have positive results. Cheers Dick Richard K. Thigpen GCOS Secretariat 301-598-5683 301-452-7669 41 22 730-8068 (in Geneva) [1]thigpenr@erols.com [2]RThigpen@wmo.int >>> 8/17/2007 6:41 AM >>> Hi, Udo et al., I'm delighted to see you actively involved in the quest to better the GSN. My view is actually a little beyond Phil's. The places left in the world where we don't have GSN but could use some are most likely the places with very poor international exchange of data. So it might even be appropriate to focus specifically on stations that are not reporting well and seek to improve them. Indeed, the Lead Centers that Dick has been encouraging along seem to be making some progress in that direction already. So perhaps they will be up to new challenges!
