To generate detailed surface elevation of polar ice sheets
The detailed surface elevation of the ice sheets is an important component of any model of ice sheet dynamics, air flow, temperature, or accumulation. Past research has pioneered the use of AVHRR and MODIS images, combined with other elevation data, to provide new, high-resolution elevation maps through photoclinometry (shape-from-shading). We are currently investigating several possible approaches using MODIS imagery and ICESat elevation profiles. A preliminary product of this work was the generation of the MODIS Mosaic of Antarctica (MOA) and a related MODIS Mosaic of Greenland (MOG).
