Hello, I have recently read an interesting article about integrating Limited Area Models (LAMs) into kriging with external drift for temperature (Libertà et al. link below).
www.wmo.int/pages/prog/www/IMOP/.../IOM.../P2(05)_Perini_Italy.doc As I understand, it seems that the authors generated variograms with the differences between the closest LAM grid point and the ground point. Then, they used kriging with external drift where the ground observation stations were the primary data and the secondary data was the LAM. Conceptually, is it possible to generate a variogram with differences and then krig the data rather than the differences? I would appreciate anyone's explanations or corrections to my understanding. Thank you, Cara [[alternative HTML version deleted]]
