ARCTAS: Measuring the Arctic’s Haze and Smoke
The Arctic is often perceived as a pristine place,
located as it is far from the world’s smokestacks.
And yet its atmosphere serves as a receptor for
air pollution from the industrial regions of North
America, Europe, and Asia. The reddish-brown soup of pollution that peaks
in late winter and early spring even has a name—Arctic
haze. During the summer, smoke from wildfires joins
the mix. This spring and summer, NCAR researchers from
ESSL/ACD and EOL are supporting a NASA field project
to investigate the chemistry of the Arctic’s
lower atmosphere.
Weather Research & Forecasting Model (WRF) version 3.0, released
On April 8, 2008, WRF 3.0 was released. The current WRF (Weather Research and Forecasting Model) software
framework supports two dynamical solvers: the Advanced Research
WRF (ARW, Users' page)
developed and maintained by the Mesoscale and Microscale Meteorology
Division of NCAR, and the nonhydrostatic Mesoscale Model (NMM, Users' page) developed by the National Centers for Environmental Prediction with user support provided by the Developmental Testbed Center.
A Synthesis and Assessment of the Effects of Climate Change on U.S. Ecosystems
Published May 27, 2008, the Synthesis and Assessment Product 4.3 (SAP 4.3): The Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States is the most extensive examination of the impacts of climate change on important U.S. ecosystems undertaken to date.

Black carbon aerosols cause reduced monsoon rainfall over India
Yahoo India (16 July 2008)
Researchers from the National Center for Atmospheric
Research have analyzed that black carbon aerosols cause reduced monsoon
rainfall over India. They analyzed a six-member ensemble of
twentieth-century simulations with changes to only time-evolving global
distributions of black carbon aerosols in a global coupled climate
model to study the effects of black carbon (BC) aerosols on the Indian
monsoon. [read more]

Education & Outreach
You can explore the atmosphere, too. From the learning games on Kid's Crossing, to Windows to the Universe, there are many ways to learn about our atmosphere, and the scientists who study it.
There are opportunities for undergraduates with internship programs such as SOARS; and Post graduate students should explore the opportunities to work with NCAR, via the Advanced Study Program.
NCAR is committed to developing and enhancing public interest in and understanding of science. Educators can take an online course, view teaching resources by grade-level in the Educator's Bridge, or get up-to-speed on Weather & Climate Basics.
