ABSTRACT - A better understanding of the key characteristics influencing consumers' perception and purchase decisions of mandarins can contribute to the selection of new cultivars that assertively meet their needs and expectations, as well as to the development of strategies to increase mandarin consumption in the different markets. In this context, the aims of the present work were:i) to explore Uruguayan consumers' perception of mandarins, and ii) to identify the key characteristics that drive mandarin purchase decisions.

ABSTRACT - Evapotranspiration (ET) is a key process in hydrological systems and, consequently, in agroecosystems. It can be measured or derived with a large variety of models at scales ranging from leaf to catchment. MODIS16A2 is a satellite ET product with 500 meters / 8-day spatio-temporal resolution worldwide. It is based on the Penman-Monteith equation and considers the effect of vegetation dynamics, albedo and land cover.

ABSTRACT. Accurate estimation of aerial net primary production (ANPP) using remotely acquired data is one of the main challenges in both environmental monitoring and precision agriculture. Reflectance-based techniques have been widely used for decades, but detection of fluorescence emission by chlorophyll has emerged as a promising alternative in recent years. Although passive sun-induced fluorescence (SIF) monitoring has shown interesting results, the information it provides is limited to few wavelengths (Fraunhofer and telluric lines).
