Tropospheric Ozone Production about the Spring Equinox (TOPSE), 2013 - 2016

Series

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.

Biographical / Historical

The TOPSE investigation combined model studies and simulations with a set of chemical and photochemical measurements taken over the critical winter-spring transition in the northern mid-to-high latitude troposphere. The overall goal of the experiment was to investigate the chemical and dynamic evolution of tropospheric chemical composition over mid- to high-latitude continental North America during the winter/spring transition; a particular emphasis was placed on the springtime ozone maximum in the troposphere. As the experiment progressed additional effort was used to investigate dramatic ozone depletion events found over large regions of the Arctic surface layer. The Tropospheric Ozone Production about the Spring Equinox took place in 2000 in Colorado, Greenland, and Manitoba.
