In this paper, we present an algorithm to correct the horizontal reflectivity factor Zh for attenuation by absorption plus scattering of a polarimetric radar located at the Experimental Station of INTA, in Oro Verde, Entre Rios, Argentina. Data correspond to two storms which occurred on November 18, 2009. The correction obtained was compared with models from the literature. Results show good agreement for regions with reflectivity factor lower than 55 dBZ while for regions that go over this limit, the corrections are different. Comparisons with rain gauges indicate the need of more statistics to improve the correlation.
