Hi everyone,

The next ATOC Colloquium will be held in a hybrid format on *Friday,
October 28 from 11a–12p MT over Zoom and in SEEC S228. *This week's
colloquium will feature a seminar from *Dr. Alia Khan (Western Washington
Univ.)* entitled, *"From Field Sites to Satellites: Exploring the Role of
Black Carbon and Algae on Snow Albedo and Melt in a Changing Climate *".
The zoom login information and abstract for the colloquium are provided
below. Please join us for coffee and conversation beginning at 10:45am MT,
and stay afterwards for a lunch catered by Illegal Pete's.
Please let us know if you have any questions or are interested in
delivering a talk at a future colloquium. A full schedule of ATOC colloquia
can be found at https://www.colorado.edu/atoc/colloquium.

We look forward to seeing you on Oct. 28!

*From Field Sites to Satellites: Exploring the Role of Black Carbon and
Algae on Snow Albedo and Melt in a Changing Climate *
Alia Khan (Western Washington Univ.)

The cryosphere is experiencing dramatic change. Intensifying wildfire
seasons are enhancing the production and deposition of black carbon on snow
and ice surfaces. Additionally, snow algae are ubiquitous in some seasonal
snowpacks, such as across the North Cascades and West Antarctic Peninsula.
The presence of snow algae blooms and light absorbing particles, like black
carbon, enhance the absorption of solar radiation by snow and ice
surfaces.  I will discuss the interdisciplinary approaches that my
students, colleagues, and I are taking to combine snowpack biogeochemistry
and optical remote sensing, to study the radiative forcing of snow algae
and light absorbing particles and their impact on snow melt.  With support
from NSF and NASA, we are developing novel tools to investigate the spatial
and temporal distribution of snow algae, black carbon and dust across the
cryosphere, their response to climate warming, and their role in regional
snow and ice melt.
