CalNex-LA

A shorcut to this page is http://tinyurl.com/CalNex.

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.

Other Coordinated Studies

• DOE is carrying out the CARES Campaign in the Sacramento area in conjunction with CalNex.
• The SJV CalNex Supersite will be located on University of California Property in Bakersfield near the corner of S. Mt. Vernon Street and E. Belle Terrace. Coordinates estimated from GOOGLE EARTH: 35°20'46.15"N, 118°57'55.87"W

Dates and Location

The dates for all the platforms of the larger CalNex campaign, including the LA ground site, are at http://tinyurl.com/calnexschedule.

The FINAL dates for the CalNex-LA site are:

• Setup and start of measurements: week of May 7-14
• Official measurement period: May 15 0:00 to June 16 0:00
• Tear Down: June 17-19

These dates were partially chosen to maximize overlap with other platforms, especially the NOAA P3 and the R/V Atlantis.

The site is planned 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

• As an editable Google Spreadsheet with the link that was sent by email to everyone (email Jose if you want to be able to edit directly and did not get or have lost that link)
