AbstractThe main objective of the CRYSYS project is to develop an information system for understanding and monitoring the impact on northern environments of global warming caused by increased CO2 concentration. Both historical data, and data collected over the next 25 years are integral to the success of this project. Satellite observations, ground climate records and geophysical observations will all contribute to our understanding of these impacts. CRYSYS will also include the development and validation of various cryospheric models.

The major research component of CRYSYS is to create a methodology for extracting information on the cryoshere from remotely sensed data. Information on geophysical variables such as sea ice, land ice permafrost and snow cover will help us understand and model atmosphere-ocean-cryosphere interactions. These cryospheric models will be used to evaluate and monitor the effects of global change in northern environments. CRYSYS is part of the National Aeronautics and Space Agency's (NASA) Earth Observing System (EOS) in support of the Global Change Mission to the Planet Earth program.
