This page is a repository of information and links for preparing and executing the field experiment at the Los Angeles Supersite as part of the CalNex-2010 field campaign. The focus of the campaign is to study nightime chemistry (led by Jochen Stutz of UCLA) and formation of secondary organic aerosol (led by Joost de Gouw of NOAA and Jose-Luis Jimenez of CU-Boulder). Prospective investigators who are interested in participating in this study should contact these PIs.
There is no specific call for proposals for CalNex-LA. NOAA investigators will be funded by internal NOAA funds, while university investigators need to find relevant funding. CARB and NOAA are funding a limited number of external investigators.
Logistical Information
Tentatively the site is planned to be located at the Los Angeles North Main St. site, which has been used for air quality monitoring in LA for a long time. It is just 2 miles N of downtown LA, in a building of the LA Division of Water and Power. This is a link to a map of the site in Google Maps
Planned and Instrumentation
Several additional instruments have been proposed, and will be deployed here is sufficient funding is available to the PIs.
