Abstract
The MODIS (Moderate Resolution Imaging Spectroradiometer) scanner makes subframe measurements in some of its bands to increase the spatial resolution from its standard 1km resolution to 500m or 250m. This is achieved by sampling a detector of a high resolution band at twice (or four times) the sampling rate of the 1km bands. This paper shows that a calibration equation nonlinear with radiance and specific to the individual subframes will reduce striping in the images. The effects are significant for low radiance levels like those encountered over ocean scenes. A preliminary calibration correction is derived with two approaches: first from prelaunch measurements, then from on-orbit data. The results of the two methods are qualitatively similar.
