This document was created by the Solar Simulations for the Atacama Large
Millimeter Observatory Network (SSALMON) in preparation of the first regular
observations of the Sun with the Atacama Large Millimeter/submillimeter Array
(ALMA), which are anticipated to start in ALMA Cycle 4 in October 2016. The
science cases presented here demonstrate that a large number of scientifically
highly interesting observations could be made already with the still limited
solar observing modes foreseen for Cycle 4 and that ALMA has the potential to
make important contributions to answering long-standing scientific questions in
solar physics. With the proposal deadline for ALMA Cycle 4 in April 2016 and
the Commissioning and Science Verification campaign in December 2015 in sight,
several of the SSALMON Expert Teams composed strategic documents in which they
outlined potential solar observations that could be feasible given the
anticipated technical capabilities in Cycle 4. These documents have been
combined and supplemented with an analysis, resulting in recommendations for
solar observing with ALMA in Cycle 4. In addition, the detailed science cases
also demonstrate the scientific priorities of the solar physics community and
which capabilities are wanted for the next observing cycles. The work on this
White Paper effort was coordinated in close cooperation with the two
international solar ALMA development studies led by T. Bastian (NRAO, USA) and
R. Brajsa, (ESO). This document will be further updated until the beginning of
Cycle 4 in October 2016. In particular, we plan to adjust the technical
capabilities of the solar observing modes once finally decided and to further
demonstrate the feasibility and scientific potential of the included science
cases by means of numerical simulations of the solar atmosphere and
corresponding simulated ALMA observations.Comment: SSALMON White Paper with focus on potential solar science with ALMA
