Revisiting measurement and representation errors in geophysical sciences: From classical collocation‐based measurement error estimation to “sampling‐aware field‐informed retrieval”, a method that explicitly accounts for representation errors Open
The quantities of interest in geosciences (e.g., atmospheric wind, rock porosity) typically exhibit structure across a wide range of spatial and temporal scales. As a result, it is insufficient to define measurement errors as some deviatio…
