From Bernard.Dost at knmi.nl Mon Jan 5 03:45:09 2009 From: Bernard.Dost at knmi.nl (Dost, Bernard (KNMI)) Date: Mon, 5 Jan 2009 12:45:09 +0100 Subject: [fdsn-wg2-data] FW: next meeting WG-2 in Cape Town Message-ID: <1AD866A4F45E8C459D8C6A14F6CAFAE096DEF0@BCSXTC.knmi.nl> Dear subscribers to the fdsn wg2 list, Recently I sent around the email I enclose to the members of the WG2 I have in my own list. I realized that I did not sent the email to the FDSN listserver and that is what I did now. If you receive the email twice, sorry. Best regards Bernard ________________________________ From: Dost, Bernard (KNMI) Sent: 02 January 2009 11:12 To: Bernard Dost; Genevieve Roult; Harold Bolton; Jim Lyons; Pete Davis; Ray Buland; Salvatore Mazza; Seiji Tsuboi; Tim Ahern; Winfried Hanka Cc: Sleeman, Reinoud (KNMI); Eck van, Torild (KNMI) Subject: next meeting WG-2 in Cape Town Dear members of FDSN WG-2, First of all: all the best for 2009 to you all. According to the distributed schedule, we will have a meeting in Cape Town on Monday jan 13 13:00-14:30. As an agenda I propose a similar one as last meeting: 1. SEED issues 2. Real time data exchange- protocols and methods 3. Standard interface to link distributed centers 4. Redistribution of data 5. XML developments (QuakeML) 6. Proposal station codes I enclose the latest version of the draft on station codes that I received from Ray Buland. Also, I enclose a request to discuss the possibility to register a mime type for SEED data. If we have too little time for a thorough discussion on the station coding issue, we might proceed on Tuesday in a separate meeting that is proposed by Ray. Although I did book my travel and hotel for the conference, there is a possibility that I might have to cancel my trip at the last moment due to personal circumstances. If this happens I will inform you and maybe Tim can be the chairperson for the meeting instead. Hope to see you all soon and sorry for being late with my email.

Please find enclosed an additional issue for next weeks meeting Regards Bernard ________________________________ From: Seiji Tsuboi [mailto:tsuboi at jamstec.go.jp] Sent: 07 January 2009 09:03 To: Dost, Bernard (KNMI) Cc: 'Seiji Tsuboi'; 'NAKAMURA Takeshi' Subject: RE: next meeting WG-2 in Cape Town Dear Barnard I am sorry for very late reply to your email. JAMSTEC will install ocean bottom cable observation system offshore of Japanese Islands by the end of this year. We hope to use mini-seed format to send realtime data from the ocean bottom station to the data center. We would like to attach several new blockettes to the mini-SEED data to monitor the sensor status. The attached file explains our proposed format to mini-SEED. Takeshi Nakamura of JAMSTEC will attend the WG meeting and hope to explain this at the meeting. If you will not be able to attend the meeting, please let me know. I will forward the email to Tim. Best regards, Seiji Tsuboi ________________________________ From: Dost, Bernard (KNMI) [mailto:Bernard.Dost at knmi.nl] Sent: Friday, January 02, 2009 7:12 PM To: Bernard Dost; Genevieve Roult; Harold Bolton; Jim Lyons; Pete Davis; Ray Buland; Salvatore Mazza; Seiji Tsuboi; Tim Ahern; Winfried Hanka Cc: Sleeman, Reinoud (KNMI); Eck van, Torild (KNMI) Subject: next meeting WG-2 in Cape Town Dear members of FDSN WG-2, First of all: all the best for 2009 to you all.

If there are any comments/additions, let me know. There are a number of actions, especially concerning the SEED issues. I would appreciate it if you could react within the next three weeks to the proposal from Doug Neuhauser on the definition of band code in terms of sample rate and corner frequency and also on the proposal by Nakamura/Tsuboi. I would like to ask Ogie if he could help us to reach the vendors of instrumentation in order to get their comments on the Nakamura/Tsuboi proposal Best regards Bernard -------------- next part -------------- An HTML attachment was scrubbed...

These generally are in miniSEED format Traditional Requests. These requests are formatted in a way where the Data Center actually knows the Name and Institution of the person requesting the data. Well at least we know what they entered into the relevant fields. The lowest common denominator for these requests is what is in a BreqFast request. What the IRIS DMC has been doing for some network operators for many years is sending BreqFast images of these requests to the relevant data center. From this information the data center can generate the statistics it needs to show data redistribution. The IRIS DMC would propose that the FDSN adopt this format for reporting redistributed data. It is already in use with data centers such as GEOFON, ORFEUS, GEOSCOPE, MEDNET and CANADA. We think it is as simple as it can be and still convey the needed information. Here is a sample that I believe is clear. The BreqFast format is documented at http://www.iris.edu/manuals/breq_fast.htm and relates directly to the infomration found in the example below.
