<abstract>
The WDC-SILSO is an activity of the Operational Directorate "Solar Physics and Space Weather" also
known internationally as the Solar Influences Data analysis Center (SIDC). The SIDC is a department
of the Royal Observatory of Belgium. Its mission is to preserve, develop and diffuse the knowledge of
the long-term variations of solar activity, as a reference input to studies of the solar cycle mechanism
and of the solar forcing on the Earth's climate. The work realized at WDC-SILSO is under supervision
from the IAU, URSI and IAGA. They provide endorsement of the World Data Center SILSO, with regard to
the scientific usefulness and quality of the sunspot data produced and archived by this data center.
