The Atmospheric Imaging Mission for Northern Regions: AIM-North

The AIM@SHAPE Adventure: Mission and Results

During the period 2004 − 07, the AIM@SHAPE Network of Excellence has fostered the development of new methodologies for modelling and processing the knowledge related to digital shapes. This knowledge is concerned with the geometry (the spatial extent of the object), the structure (object features and part-whole decomposition), the attributes (colors, textures), the semantics (meaning, purpose),...

Target Atmospheric CO2: Where Should Humanity Aim?

Paleoclimate d ata show that climate sensitivity is ~3°C for doubled CO2, including only fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks, i s ~6°C for doubled CO 2 fo r the range o f cl imate states between glacial conditions and ice-free Antarctica. Decreasing CO2 was the main cause of a cooling trend that began 50 m illion yea rs a go, the pl anet b...

Atmospheric Processes Governing the Northern Hemisphere Annular Mode/ North Atlantic Oscillation

Springtime Atmospheric Responses to North Atlantic SST Anomalies in Idealized GCM Experiments: Northern Hemisphere Circulation and North American Precipitation

In this study, a series of experiments using idealized sea surface temperatures (SST), land and orography are performed to examine the interactions between the Atlantic Multidecadal Oscillation (AMO), continents and major orography. Three sets of experiments are done using an increasingly realistic surface boundary (aqua-planet, land without orography and land with orography) and run using perp...

Galileo multispectral imaging of the north polar and eastern limb regions of the moon.

Multispectral images obtained during the Galileo probe's second encounter with the moon reveal the compositional nature of the north polar regions and the northeastern limb. Mare deposits in these regions are found to be primarily low to medium titanium lavas and, as on the western limb, show only slight spectral heterogeneity. The northern light plains are found to have the spectral characteri...
