Revision as of 20:45, 10 October 2009

This page is a repository of information and links for preparing and executing the field experiment at the Los Angeles CalNex 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.

(*) Not to be confused with the Southern CA EPA Supersite which is headed by Costas Sioutas and located elsewhere.

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.

Dates and Location

The tentative dates for the CalNex-LA site are 5 weeks of measurements (not including setup time) within May 10-June 28, 2010. The exact dates should become clear in early Fall 2009.

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 Instrumentation

This information is now kept as a Google Spreadsheet due to easier formatting and modification. It can be viewed in two ways:

  • As a non-editable web page by anyone here
