An efficient algorithm for the large-scale smoothing of scattered data retrieved from remote sounding experiments

We present a new algorithm for smoothing/interpolation of two-dimensional fields applicable to noisy data observed at scattered sites. The technique is based on a special statistics allowing one to simultaneously minimize the fit residual and the correlation between residuals of adjacent poi...
