Inter-Division B-E WG Coordination of Synoptic Observations of the Sun — Functional


The mission of this working group is to facilitate international collaboration in synoptic long-term solar observations, which includes past, current, and future synoptic programs, preservation, calibration, and access to synoptic solar data products. The working group provides a forum for discussion of all issues relevant to synoptic long-term observations of the Sun including (but not limited to) coordination between synoptic programs in different countries (both in respect to exchange of information and planning for future synoptic programs) and a proper calibration of historical data from different sources (e.g., sunspot drawings, CaK plage indices, magnetic field measurements etc).
