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...

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 points. The principle of the method
is first explained in the 1-D case and then extended to the 2-D case by
adjunction of a regularization operator. The method is compared with different
algorithms (Loess-Renka, Biharmonic Spline and kriging) in three test cases
related to remote sounding of the Earth’s atmosphere by space-borne
experiments.<br><br><b>Key words. </b>Atmospheric composition
