What Does OI Stand For?
OI stands for Optimal Interpolation
Optimal Interpolation (OI) is a statistical technique used in data assimilation and geophysical sciences to estimate the values of a variable at unsampled locations. By leveraging available observations and their uncertainties, OI produces optimal estimates that minimize the error variance, effectively combining model predictions and observational data. This method is widely applied in areas such as meteorology, oceanography, and environmental monitoring to improve the accuracy of spatial field representations.
