Draft Action Items
October 11-12, 2007
PASSCAL Experiment Listings. The DMS Standing Committee views
information about the data availability of completed PASSCAL experiments
as important information for the community. Therefore, we recommend
adding a link from the public web pages of the IRIS DMC to the
data table maintained by the PASSCAL data center (http://tst.iris.edu/data/passcal/passcal_exp.htm).
The table should be appropriately abbreviated to omit PI's email
addresses and omission of redundant data. It should be clear
that the various columns are clickable to produce user controlled
sorting of the columns.
Responsible: Wiens will make sure this information is presented to the COCOM.
EM Seafloor Data. The DMSSC supports the conversion of
EM data to SEED format and archiving at the IRIS DMC. This
task should be coordinated between Davis and Constable at SIO
and Ahern at the IRIS DMC. IRIS should insure that proper
linkages are made to the Marine Geophysical Data System at Lamont.
Responsible: Davis and Ahern
Derive long period data from broadband data for selected networks. The
GTSN and Canadian networks should be the first candidates for
this processing. (Continuing Task from Previous Action Items.)
The DMS would like to improve customer support (e.g. response
to specific user inquires) while improving the efficiency of this
support on the staff side. The DMSSC suspects that other
IRIS programs may have similar needs. DMS representatives to COCOM
should present this issue and see if other groups have similar
concerns and may support a coordinated user support capability
Obtain information about the decommissioning process applied
to TA stations. Insure things such as calibrations and orientation
are confirmed before dismantling stations. Woolley to forward
information to DMSSC.
Implement new algorithm for SPYDER®/FARM products for USArray
and US Regional network stations. Stations that record EH,
BH, SH and HH channels are to be included.
Form an IRIS Software Working Group. Write a document to define
the working group’s charge and mission. This
working group should include activities that, at least, address:
1) Software engineering: to align technologies with community CyberInfrastructure efforts and “fine tune” the tools. This would be a high-level design review. The Working group would focus on the Application Program Interfaces, i.e. the inputs and outputs and their formats ensuring that terms are well-defined.
2) Usability studies to understand what users need, and make sure this matches with what IRIS is providing.
DMSSC Recommended membership should include representatives from
UNIDATA (Domenico), SCEC (Maechling), MGDS (Arko), GEON (Baru),
with IRIS Members of Ammon, Brodsky, Koper and Wiens. IRIS
Staff to include Ahern, Woodward and Casey.
Responsible: (development of the charge and the working group’s mission) Woodward
DMSSC recommends moving forward with producing merged data
(M quality Factor). Issues to be resolved include
investigate timing of Baler data and coordination with DCCs
to see if M data should be produced if Q data is available.
DMSSC agrees that archiving data from the Brazilian data
of Berrocal is a welcome addition to the DMC holds and approves
management of these data.
Redistribution of IRIS Generated Data (GSN and PASSCAL). Adopt
a policy of data center redistribution that encourages redistribution
of IRIS data by other data centers. Insure that techniques
are in place that allows IRIS to obtain statistics related
to the data redistribution. Work within the FDSN framework
to implement the redistribution policy.
Alert the COCOM and BoD about end of life of the Powderhorn
mass storage system in 2010. There could be a large capital
item in future budgets.
The DMSSC expresses interest in management of SEAM data
set if and when the opportunity arises.
The DMS Strategic Plan needs to be updated by the 2008
Spring DMSSC Meeting. DMSSC to provide input by end
Develop a charge for the DMS Web committee that will identify
the approach in redesigning DMS web presence. Insure
that proper linkages exist with other IRIS programs and
the overall corporate restructuring.
The plan for use of FY07 DMS carryover was approved as
presented by Ahern. Present this plan to the COCOM.
