Spectral Crop Coefficient Approach for Estimating Daily Crop Water Use
《Advances in Remote Sensing》2014年第3期197-207,共11页Nithya Rajan Stephan J. Maas 
While the amount of water used by a crop can be measured using lysimeters or eddy covariance systems, it is more common to estimate this quantity based on weather data and crop-related factors. Among these approaches,...
