Goals of ground-based solar observations.
Abstract
Fruitful observations from spacecraft as well as from ground-based observatories both require close and coordinated cooperation between observers and theoreticians. Advantages of ground-based observations are the possibilities for studying long-term variations (many years), even outside active regions, and the fact that large telescopes with complex instrumentation can be used. Disadvantages are the limitations on the usable wavelength region and the distorting influence of the Earth's atmosphere. Promising attempts to minimise these distortions have, however, been made by applying new technologies. Nevertheless, observations of very small structures (≤0.2 arcsec) in the visible region over extended periods (many hours) will probably forever remain the domain of spaceborne instrumentation.
