Integration of CO 2 flux and remotely-sensed data for primary production and ecosystem respiration analyses in the Northern Great Plains: potential for quantitative spatial extrapolation (2005, background): “Such models may have limited robustness given high correlations among radiation input, temperature, and humidity; and Choudhury (2001) has reasonably cautioned about possible regional biases.”
Estimation of vegetation water content and photosynthetic tissue area from spectral reflectance: a comparison of indices based on liquid water and chlorophyll absorption features (2003, background): “LAI, rather than total green tissue area, is the parameter most often used in models of canopy photosynthetic rates (Choudhury, 2001; Sellers et al., 1996), and thus previous studies have focused on the relationship between water indices and LAI (e.”
Gross primary production and ecosystem respiration of irrigated and rainfed maize–soybean cropping systems over 8 years (2012, background): “…in GPP and light use efficiency due to diffuse light have been reported in maize and other ecosystems (e.g., Knohl and Baldocchi, 2008, Alton et al., 2007a, Alton et al., 2007b, Gu et al., 2003, Gu et al., 2002, Turner et al., 2003 and Choudhury, 2001), but not quantified on a growing season basis.”
