Abstract

The accuracy of the MODerate Resolution Imaging Spectroradiometer (MODIS) end data products is affected by the spatial response in the form of the Modulation Transfer Function (MTF). This effect is most noticeable near spatial transition periods where the contrast changes are high. This research effort is an estimate the MODIS MTF using a simplified model, based on Santa Barbara Research Center's MTF model. The simplified MTF model is incomplete, and MTF validation laboratory data are used to complete the model by estimating the unknown parameters. The laboratory data were taken using the Internal Alignment Collimator, a line spread function calibration instrument. Using the completed MTF model, a MTF correction filter is derived. The filter corrects the along-scan and along-track optical blurring and the along-scan non-zero integration time. The filter reduces the Point Spread Response (PSR) footprint by sharpening the response. The correction filter is applied to MODIS level 1B data using a scene from Mono Lake September 29, 2000 and a scene from the Maricopa Agricultural Center (MAC) September 26, 2000.
