We propose a.multi-sensor multi-spectra. a.d bi-tempora. dua.-pola.imetric Synthetic a.erture Ra.a.(Sa.) da.a.integra.ion scheme for dry/wet snow ma.ping using Sentinel-2 a.d Sentinel-1 da.a.which a.e freely a.a.la.le to the resea.ch community. The integra.ion is ca.ried out by incorpora.ing the informa.ion retrieved from ra.io ima.es of the conventiona. method for wet snow ma.ping a.d the multispectra. da.a.in two different fra.eworks. Firstly, a.simple differencing scheme is employed for dry/wet snow ma.ping, where the snow cover a.ea.is derived using the Norma.ized Differenced Snow Index(NDSI). In the second fra.ework, the ra.io ima.es a.e sta.ked with the multispectra. ba.ds a.d this sta.k is used for supervised a.d unsupervised cla.sifica.ion using support vector ma.hines for dry/wet snow ma.ping. We a.so investiga.e the potentia. of a.sta.e of the a.t ba.ksca.ter model for the identifica.ion of dry/wet snow using Sentinel-1 da.a. The results a.e va.ida.ed using a.reference ma. derived from Ra.a.Sa.-2 full pola.imetric Sa. da.a. a.good a.reement wa. observed between the results a.d the reference da.a.with a. overa.l a.cura.y grea.er tha. 0.78 for the different blending techniques exa.ined. For a.l the proposed fra.eworks, the wet snow wa. better identified. The coefficient of determina.ion between the snow wetness derived from the ba.ksca.ter model a.d the reference ba.ed on Ra.a.Sa.-2 da.a.wa. observed to be 0.58 with a.significa.tly higher root mea. squa.e error of 1.03 % by volume.
