Conveners
Greg Kopp and Jerry Harder set the agenda, which stimulated discussion
leading to many interesting and lively discussions. Gary Rottman
began the workshop with a brief review of the past six months,
including the January 25th launch. He presented a broad overview
of the current SORCE status, which is very positive. The four
LASP instrument scientists (TIM – Greg Kopp, SIM –
Jerry Harder, SOLSTICE – Bill McClintock, XPS – Tom
Woods) continued with individual instrument overviews. This included
early on orbit commissioning activities; a description of both
the normal operating modes and special calibration modes; a review
of preliminary measurement collection methods, results, and concerns;
and a summary of ongoing validation methods and plans.
For intercomparison purposes, outside speakers and representatives
from various different space missions proposed data availability
and results from their projects. These included ACRIM III, SOHO
(DIARAD and PMOD), ERBE, SOLSPEC, SBUV/2, UARS (SUSIM and SOLSTICE),
and TIMED. The discussion provided a solid foundation of data
compatibility and suitability. Attendees now have a solid foundation
to press forward with SORCE data validation.
There was also discussion of various laboratory campaigns that
will be extremely valuable in the data validation effort. For
example, the aperture intercomparison activity that is underway
at NIST will have a major impact on SORCE and the other programs
as well.
The meeting then broke into splinter groups based on the different
SORCE observations to discuss specific instrument and data validation
concepts. One overall goal for the workshop was to define a plan
for the SORCE instrument and data validation. With this in mind,
people shared their

experiences, advice,
opinions, and desires about what they believed the direction for
the SORCE instruments and data validation process should be.
Chris Pankratz from LASP gave an overview of the SORCE data production
and data access. The SORCE data products produced by the Science
Data System located at the LASP Science Operations Center are
total solar irradiance (TSI) and spectral solar irradiance (SSI).
The various Data Product Levels (0 - 4) were described, along
with the availability information. He concluded with a summary
of the Goddard Distributed Active Archive Center (DAAC) access
sites and other Goddard Earth Sciences DAAC services. SORCE data
products will be available to the public at the end of May through
the DAAC.
The workshop closed with a summary from each of the SORCE instrument
scientists on where they saw the validation process heading and
how they hoped to get from here to there. The input and interactions
from the attendees was extremely useful. Overall, it was a very
positive meeting and brought issues, solutions, and priorities
into focus. It was a general consensus that the SORCE measurements
will have a major impact on future studies of the Sun and its
influence on our environment.
The SORCE team is beginning to plan for a broad and general Science
Team Meeting to be held next fall. This meeting is tentatively
scheduled for early December and logistical details will be coming
out in June, when exact dates and a location are determined. The
agenda will be set later in the summer. SORCE
