  abstract = {{C}urrently, studies show that only 10-30% at best of the organic matter dissolved in cloud water is characterized and sugars are among the compounds still unexplored. {N}umerous studies on the atmospheric particulate matter ({PM}) demonstrate their ubiquity, and their incorporation into cloud phase is therefore expected in light of their solubility. {I}n this work, a large array of sugars are measured at low concentration levels with an innovative {LC}-{MSMS} technique in 28 cloud water samples collected at the puy de {D}ome and their environmental variability is analyzed. {T}he total sugar concentration reaches 4.0 mu mol {L}-1, with an average value of 0.98 +/- 0.94 mu mol {L}-1, with no clear seasonal trend. {T}his represents on average 1.2% of dissolved organic carbon but reaches up to 3.7% for one sample. {T}he most abundant sugars is levoglucosan (average 247.2 nmol {L}-1) followed by glucose (168.2 nmol {L}-1), mannitol (136.5 nmol {L}-1) and 2-methyl-tetrols (130.6 nmol {L}-1). {R}eactivity in the aqueous phase is simulated with the cloud chemistry model {CLEPS} to gain insights in the half-life time of four selected compounds in different meteorological and chemical scenarios. {R}esults show a fast degradation of sugars in the aqueous phase, especially during summer, that could question the use of these tracers for long range transport in the free troposphere.},
