  In December 2016, the Atacama Large Millimeter/submillimeter Array (ALMA)
carried out the first regular observations of the Sun. These early observations
and the reduction of the respective data posed a challenge due to the novelty
and complexity of observing the Sun with ALMA.
  The difficulties with producing science-ready time-resolved imaging products
in a format familiar and usable by solar physicists based on the measurement
sets delivered by ALMA had so far limited the availability of such data. With
the development of the Solar ALMA Pipeline (SoAP), it has now become possible
to routinely reduce such data sets.
  As a result, a growing number of science-ready solar ALMA datasets is now
offered in the form of Solar ALMA Science Archive (SALSA).
  So far, SALSA contains primarily time series of single-pointing
interferometric images at cadences of one or two seconds. The data arrays are
provided in FITS format.
  We also present the first version of a standardised header format that
accommodates future expansions and fits within the scope of other standards
including the ALMA Science Archive itself and SOLARNET. The headers also
include information designed to aid the reproduction of the imaging products
from the raw data. Links to co-observations, if available, with a focus on
those of the Interface Region Imaging Spectrograph (IRIS), are also provided.
SALSA is accompanied by the Solar ALMA Library of Auxiliary Tools (SALAT) that
contains IDL and Python routines for convenient loading and quick-look analysis
of SALSA data.
