  abstract = {{M}onitoring precipitation in mountainous areas using traditional tipping-bucket rain gauges ({TPB}) has become challenging in sites with strong variations of air temperature and wind speed ({W}s). {T}he drop size distributions ({DSD}), amount, and precipitation-type of a {P}arsivel {OTT}2 disdrometer installed at 4730 m above sea level (close to the 0 degrees {C} isotherm) in the glacier foreland of the {A}ntisana volcano in {E}cuador are used to analyze the precipitation type. {T}o correct the {DSD}s, we removed spurious particles and shifted fall velocities such that the mean value matches with the fall velocity-diameter relationship of rain, snow, graupel, and hail. {S}olid ({SP}) and liquid precipitation ({LP}) were identified through -1 and 3 degrees {C} thresholds and then grouped into low, medium, and high {W}s categories by k-means approach. {C}hanges in {DSD}s were tracked using concentration spectra and particle's contribution by diameter and fall velocity. {T}hus, variations of concentration/dispersion and removed hydrometeors were linked with {W}s changes. {C}orrected precipitation, assuming constant density (1 g cm(-3)), gives reliable results for {LP} with respect to measurements at {TPB} and overestimates {SP} measured in disdrometer. {T}herefore, corrected precipitation varying density models achieved fewer differences. {T}hese results are the first insight toward the understating of precipitation microphysics in a high-altitude site of the tropical {A}ndes.},
