With the Arctic rapidly changing, the needs to observe, understand, and model the changes
are essential. To support these needs, an annual cycle of observations of atmospheric …

Multi-year sets of ground-based sun-photometer measurements conducted at 12 Arctic sites
and 9 Antarctic sites were examined to determine daily mean values of aerosol optical …

While the representation of clouds in climate models has become more sophisticated over
the last 30+ years, the vertical and seasonal fingerprints of Arctic greenhouse warming have …

This second edition brings this definitive book completely up to date with the many advances
in our understanding of Arctic climate since the first edition was published in 2005. The book …

From 4 years of observations from Barrow, Alaska, it is shown that the cloud radiative impact
on the surface is a net warming effect between October and May and a net cooling in …

The decline of the Arctic cryosphere during recent decades has lowered the region's surface
albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the …

Dust particles, serving as ice-nucleating particles (INPs), may impact the Arctic surface
energy budget and regional climate by modulating the mixed-phase cloud properties and …

Using six flights observations in September 2015 over Hebei, China, this study shows a
robust negative aerosol‐cloud droplet effective radius (re) relationship for liquid clouds …

Aerosols that serve as ice nucleating particles (INPs) have the potential to modulate cloud
microphysical properties and can therefore impact cloud radiative forcing (CRF) and …

Arctic Ocean observations are combined to create a cloud and radiation climatology for the
early 21st century (March 2000 to February 2011). Data sources include: active (CloudSat …
