“…Also Wohlfahrt and colleagues [9] that filled the questionnaire used this approach based on broad-band NDVI sensors to estimate carbon dioxide fluxes of temperate mountain grasslands in Austria. Tower-derived NDVI values are closed to in situ NDVI [23,38] but the variability of tower-NDVI is not as high as in the radiometer in situ NDVI. Wilson and Meyers [39] and Tittedrant et al [23] reported that tower-NDVI shows close values to MODIS satellite data for grassland and crops but large scatter for forests.…”

“…Several authors proposed the use of multispectral optical sensors to derive some broadband and fine multispectral vegetation indices, as NDVI and SR [18,[38][39][40]. Also Wohlfahrt and colleagues [9] that filled the questionnaire used this approach based on broad-band NDVI sensors to estimate carbon dioxide fluxes of temperate mountain grasslands in Austria.…”

“…El 50% de aproximadamente 35 trabajos encontrados sólo utiliza la información del Usefulness Index (Índice de utilidad), un indicador sintético sobre la calidad de los datos más fácil de utilizar (e.g. Alexandridis et al, 2008;Beck et al, 2007;Colditz et al, 2006;Giner et al, 2012;Gu et al, 2009;Hess et al, 2009;Jacquin et al, 2010;Li et al, 2008;Reinart et al, 2008;Wang et al, 2005). El problema que plantea este índice es que no permite conocer cuál es el origen de la incertidumbre en la calidad final de los datos.…”

“…Por ejemplo, el efecto de las nubes ha sido ampliamente estudiado en las regiones tropicales como la Amazonía (Hess et al, 2009, Huete et al, 2006, Poulter et al, 2010, Ghana y Costa de Marfil (Colditz et al, 2006), la sabana de Madagascar (Jacquin et al, 2010). El efecto de la nieve se ha estudiado en la alta montaña (Dozier et al, 2008) o el norte de Europa (Beck et al, 2007, Reinart et al, 2008, Wang et al, 2005. Otros trabajos combinan varios indicadores como en áreas con cultivos en Estados Unidos (Zhao et al, 2010) o en la meseta china (Li et al, 2008).…”
