Atmospheric Chemistry and Observations Modeling (ACOM), 2015 -


Scope and Contents

From the Collection:

Since February 2013, the NCAR Archives has been crawling and harvesting UCAR/NCAR websites using Archive It. The harvested websites include most UCAR/NCAR webpages and associated images, video, PDF files, and other content. The collection also includes the U.S. Weather Commission, a group that brings together the American weather industry, state and local governments, and academia in an organized effort to urge Congress and the Executive Branch to undertake, promote, and support our nation’s portfolio of environmental observations and weather forecasting capabilities. In 2021 the organization began the second phase of an initiative to migrate all sites to a consistent format and move internal content to a single portal. For this internal, password-protected content a web-recorder software was used to capture material. This content is not browsable online but available by request from the archivist. This content is still considered internal-only.

Scope and Contents From the Collection:

The date ranges in this finding aid refer to the time period in which the websites were crawled. The content on the websites may reflect earlier dates.

Biographical / Historical

ACOM’s research focuses on advancing understanding and predictive capability for atmospheric composition and related processes. Research is organized around two major themes – Air Quality Prediction and Weather-Chemistry-Climate Interactions – and includes for example, a focus on issues related to the interaction of anthropogenic and biogenic chemical emissions, the effects of wildfires on air quality, and the impacts of upper troposphere/lower stratosphere (UT/LS) and middle atmosphere composition on climate. The synthesis of observations with atmospheric chemistry models is central to progress, with a focus on understanding and modeling fundamental processes. ACOM scientists work closely with the wider research community, providing intellectual leadership and facility support for measurement capabilities, laboratory and field experiments and community atmospheric chemistry models. ACOM was formed from the Atmospheric Chemistry Division (ACD) in 2015.
