AB: A Kriging interpolation technique has been applied to two-dimensional data from SABER (Sounding of the Atmosphere using Broadband Emission Radiometry), a ten-channel infrared radiometer aboard NASA's TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) satellite. These data are indicative of hydroxyl Meinel airglow emissions from the Earth's mesosphere. A hybrid Kriging cubic spline interpolation algorithm has been developed for the purpose of globally displaying the measurements. Kriging interpolation gives a minimum mean-squared error (MMSE) approximation for unknown data values using unevenly sampled spatial data points at specific latitude and longitude locations. Due to the great number of calculations and long processing time required to perform high-resolution Kriging interpolation, a hybrid technique was created which uses the Kriging estimates at a certain resolution as the input to another interpolator. A cubic-spline technique was then used to enhance the resolution of the overall image from the processed data. The hybrid interpolation technique performs well when compared with Kriging interpolation, and the processing time for each image is drastically reduced.
