Optical and electronic crosstalk in the Focal Plane Assemblies (FPAs) of satellite instruments degrades the radiometric quality of remote sensing data, and can be a major limitation to achieve performance quality needed for environmental and climate monitoring research. Correction algorithms for this effect have been developed, such as the one developed for MODIS short wave infrared (SWIR) band...

introduction quantitative susceptibility mapping (qsm) is a new contrast mechanism in magnetic resonance imaging (mri). the images produced by the qsm enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. these nuclei are targets in many clinical applications and therefore their easy localization is a must. in this study, we aimed to i...

The Multi-sensor Cloud Retrieval Simulator (MCRS) produces a “simulated radiance” product from any high-resolution general circulation model with interactive aerosol as if a specific sensor such as the Moderate Resolution Imaging Spectroradiometer (MODIS) were viewing a combination of the atmospheric column and land–ocean surface at a specific location. Previously the MCRS code only included co...

* Research supported by NASA Contract NAS5-00213. Abstract Moderate Resolution Imaging Spectroradiometer (MODIS) data are collected from the Terra satellite at a rate of 11 megabits/second. These data are to be transmitted to earth, stored, and analyzed by various algorithms. One solution to reducing the bandwidth and storage need for these data is to apply wavelet-based compression, which is k...

Title of Dissertation: MAPPING PHOTOSYNTHETICALLY ACTIVE RADIATION (PAR) USING MULTIPLE REMOTE SENSING DATA Tao Zheng, Doctor of Philosophy, 2007 Dissertation directed by: Dr. Shunlin Liang, Professor Department of Geography Incident Photosynthetically Active Radiation (PAR) is an important parameter for terrestrial ecosystem models. Presently, deriving PAR using remotely sensed data is the onl...

Past studies of the NOAA AVHRR/2 and GOES I-M imagery (e.g., Setvák et al., 1996) have shown that frozen tops of deep convective storms occasionally exhibit significant increase of cloud top reflectivity when observed in the 3.7 or 3.9 μm spectral bands. Similar storm top features have been documented in the NOAA-KLM AVHRR/3 1.6 μm spectral band (Setvák et al., 2003). Consequently, cross-compar...

A recent revision of the MODIS Land-Surface Temperature Algorithm Theoretical Basis Document (LST ATBD) was completed in April. A paper on the vicarious calibration of MODIS Airborne Simulator (MAS) thermal infrared channels based on the MAS data and field measurement data acquired in the field campaign conducted in Mono Lake, California, on March 10, 1998, was submitted in February, revised in...
