Resumen:
INTRODUCTIONRemotely sensed soil moisture (SM) studies have mainly focused on retrievals using active and passivemicrowave (MW) sensors. In this line of work, Argentine is strongly involved in MW satellite missiondevelopments. Its participation in SACD/Aquarius mission is known, as well as SAOCOM radar SM missionunder development by CONAE (http://www.conae.gov.ar). The main purpose of this mission is the retrievalof SM in the Pampas Plains, a huge area dedicated to agriculture and cattle raising. Although several coarseresolution SM products from different missions (passive and active) are available, the lack of an appropriatein situ network for SM validation has hampered their use for monitoring purposes (droughts and floods) andtheir assimilation in atmospheric and meteorological models. With this motivation in mind, we started tolook at alternative SM products evaluation methods ([1], [2]) that do not require a large in situ network.The objective of this work is to use spatial and temporal correlation analysis and Triple Collocation (TC)error analysis to evaluate patterns and behavior of coarse resolution SM products in the Pampas Plains. Theapproach is focused on interpretation of TC error maps using local ancillary data, additional satellite data(MODIS, TRMM), analysis of optical depth products and statistical indicators.
