The measurements took place in Paul Ziemann's lab at the Air Pollution Research Center of the University of California-Riverside. Paul is located in "Trailer 7", which is a building rather than a trailer, and is located between buildings 275 and 367, towards the southwest corner of the campus map. Here is a map of the UCR campus, as well as directions to the campus.
We carried out continuous ambient sampling for this period, plus selected runs in which we sampled from Paul's smog chamber at various stages of SOA reactions with different precursors.

Other Participants, Studies, and Data
Shane Murphy of the Seinfeld/Flagan group at Caltech sampled simultaneously with us after Aug. 2 in Pasadena using a ToF-AMS and other instrumentation, providing a point of spatial intercomparison within the LA Basin.
Two other studies took place at Riverside at the same time as SOAR: the first is animal exposures at UCR to concentrated airborne particles (CAPs) purposely during photochemical periods, and the 2nd will be in collections of CAP in suspensions for in vitro toxicological evaluations.
AQMD can provide 1-min. measurements at the sites of our interest upon request. Some sites of interest are:
Some Relevant References and Links
We would like to start sharing data, as soon as they are available, through an FTP site. In particular Megan McKay of the Goldstein group will start posting meteorological and gas-phase data from her group in the next couple of days, and will update them every three days.
For the time being we will use an FTP site at CU. If the total data volume becomes larger than a few hundred MB, we may need to switch to a commercial server that Nathan Kreisberg has looked into.
To be able to upload or download data, you'll need to download an ftp client. Winscp can be found at: http://winscp.net/eng/download.php.
Then you can set up a new connection to: http://cires.colorado.edu
with the username and password that Jose sent to the e-mail list on July 14, 2005 (everything lowercase, the server is case-sensitive).
In there you will see a SOAR_2005 folder, and Jose created a folder for each group. You can create as many subfolders as you want in your folder.
Please don't upload massive datasets, but rather simpler time series at this point.
Ideally all data would be loaded in two ways: as ASCII (space or comma-delimited) and as plots in PDF. If possible, paste the plots into powerpoint, and then print into PDF with two slides per page. This format is easy to see and compact.
Please also put a Readme.txt file in your main directory with a brief description of the data, and the info on the contact person for questions on the data.
Accommodations at UCR
Accommodations for study participants are available through the UCR Extension Center's International Village, which offers 1-3 and some 5 bedroom student-living style apartments that are located just off of the main campus. Occupancy rates are $49.00/night for single occupancy and $26.00/person/night for occupancy of two or more with a $200.00 refundable deposit and an application fee of $70.00 per person. Completion of a temporary-housing application is required and early reservations are suggested. For more information, contact:

On-campus parking at UCR
If you have a UC faculty or staff parking permit you can use that here for free. Otherwise you can buy a monthly parking permit for a minimum of $32 (starting when you arrive not at the beginning of the month), weekly permits for $16, or daily permits for $6. Daily permits can be obtained from automated kiosks located throughout campus. Weekly and monthly permits must be obtained from parking services (building #272 on UCR map). If you would like to park near the labs, you must buy a blue lot parking permit (available for $40). When parking near the labs, please park ONLY on the North side of Paul's lab or East of T-14. DO NOT park South of the brown trailers or West of Paul's lab as you will eventually be forced to move your vehicle. If no spaces are available near the labs, please park in the lot designated on your parking permit. Also, your apartment is about a 15 minute walk away.
Off-site storage of shipping containers
There will be a limited amount of space (~1000 cu. ft.) available off-site for storing shipping containers during the SOAR campaign. We will be reserving the majority of this space for those groups that expressed a need for off-site storage and any additional space will be available on a first-come-first-served basis. The storage facility is located approximately 3 miles from the UCR campus and a map to this facility can be found by clicking here

Standardization of time stamps and clock synchonization
Suzanne Hering is proposing that we standardize the time stamps for all data from all participants to be in Pacific Standard Time (PST). This is one hour less than the watch time, which is Pacific Daylight Savings Time (PDT). Part of the reason is that the data from the CARB and AQMD sites is always in PST. So unless anyone has a problem, we should all share data in PST.
Also please list "PST" (or PDT or UTC or whatever you decide to report on) in the label for your time data, so that it is clear what convention you are using. This issue may seem trivial but it causes extensive confusion when dealing from data from multiple groups. There have even been papers published where the data from different instruments in the same plot were not actually in the same time base!
One more issue that we wanted to bring up is clock synchronization during the study. As you may know, most computer clocks are only specified to be accurate to 1 part in 10000, or about 9 sec per day. So left unchecked, a computer clock can easily drift several minutes (sometimes more) over the duration of the study. For the instruments that have time resolution of minutes or so, this can be an important issue. So we would like to encourage everyone to establish some system to synchronize their clocks with a known good clock, preferably via the internet.
One such utility that our group has used for 5 years is "dimension4." It syncs with a variety of atomic clocks via the internet (any atomic clock will do for our needs), and it is freely downloadable. Also importantly, we have extensively tested that it can be run in the background of an acquisition computer using Labview or our AMS software, and it does not interfere with the acquisition. You can download it at:
http://www.thinkman.com/dimension4/
If you don't want to install this in your instrument computers, another option would be for you to install it in your laptop, and then modify the instrument computer manually while comparing to the laptop.

Weekly meetings
We will have weekly science meetings each Thursday at 2:00 p.m., beginning July 21st. At the first of these meetings, we will discuss a variety of outstanding logistical issues including how to organize the scientific meetings. Main goals of subsequent meetings will be to familiarize everyone with the array of instrumentation and measurements involved in the campaign and to report and discuss preliminary data from each group. Students from each group will be asked to present on a rotating basis. As we'll probably have too many people for the APRC conference room across the street, we'll meet in room 301 in the Science Laboratories I building down the hill (building #416 on the campus map).
