LBL Currents -- June 24, 1994

Rooftop devices measure wind with sound

June 24, 1994

By Mike Wooldridge, [email protected]

Keen-eared employees who have recently noticed a faint chirping outside several Lab buildings aren't hearing a new species of bird. The sounds are coming from devices that monitor the wind by "listening" to echoes bounced off of the passing air.

The Sonic Detection and Ranging Devices (SODARs) were installed on top of Bldgs. 50 and 62 in February to chart air flows around the Lab. Another site, at Bldg. 25A, is being prepared for a third SODAR. The project was a collaborative effort of the Environment, Health and Safety Division and the Facilities Department, with Nathan Hong of Facilities Architecture Engineering and Pat Thorson of EH&S leading a team of designers. Fred Bush of Facilities Maintenance and Operations coordinated LBL construction crews for the project.

LBL takes wind readings in order to predict the movement of certain pollutants--such as radionuclides--emitted from its facilities, which is required by the Environmental Protection Agency and DOE. "The lab is not a large emitter of any of these chemicals," Thorson says. "But we do have a variety of chemicals being used at a variety of locations."

The SODARs took over the wind-monitoring task from the weather tower atop Bldg. 70. Past site audits revealed that surrounding trees had grown taller than the tower, shielding it from the prevailing southwest winds. Auditors also determined that a single tower on Bldg. 70 could not accurately measure winds on the Lab's eastern perimeter, a half mile away.

The initial plan was to build taller weather towers at several sites around the lab. This was abandoned after designers determined how extensive such a project would be--LBL would need six weather towers to monitor winds lab-wide, and three of the towers would have to be more than 10 stories tall. "Towers weren't feasible just from an aesthetics point of view," Thorson says.

The design team solved the problem with SODARs. Composed of a small panel of speakers and a processing unit, the devices are about as inconspicuous as hi-tech weather-monitoring equipment gets, with each device taking up as much space as a small dumpster. The SODARs are also able to estimate the wind currents across all of LBL with only three stations. (A short tower accompanies one of the SODAR stations for quality control.)

A barrier to using SODARs in the past at many facilities was their size and the noise they made. Earlier models, used at sites such as airports and factories, had head-high, cone-shaped speakers that boomed their signals into the air. Only recently has technology miniaturized and quieted the devices, making them reasonable for locations such as LBL. Lab designers took further precautions by surrounding two of the SODARs with sound-dampening fences.

To measure the wind, a SODAR sends out a series of three high-pitched "chirps" from its speakers. The chirps are spaced about a second apart, and each is broadcasted in a slightly different direction--a center component travels directly upward from the SODAR, while two others travel at 17-degree angles to the first.

As they travel skyward, the signals are reflected back to the device by the wind. The frequency of the returning sound waves changes depending on the wind's movement. The SODAR can calculate the speed and direction of the winds by measuring the change in frequency of the echoes.

Still, even with the most advanced equipment, wind measurement isn't exactly a breeze at LBL. Local weather currents vary considerably due to the give and take between weather on the coast and the weather inland. In the daytime, especially in the summer, air currents are usually drawn eastward over the East Bay Hills as the inland air warms and rises. At night, when the inland areas cool, the winds often die down and the cooling air mass creates downslope breezes.

The varied terrain of the East Bay Hills further complicates the situation. The canyons, trees and buildings tend to channel the winds, which also affects their speeds. A light, southwest breeze blowing at Bldg. 50 might be channeled into stronger west gusts at Bldg. 62, near Strawberry Canyon.

"To my knowledge, it is really the first time someone has stationed this many SODARs on a site with terrain as complex as LBL's," Thorson says. He would like to make the LBL SODAR data available to meteorologists trying to better understand the currents that flow over the East Bay hills. More importantly, the SODAR data will be accessible to the LBL Fire Department to use in the event of a blaze in the surrounding hills, an accidental gas leak, or other emergencies.

In addition to Facilities and EH&S, building managers and the Purchasing Department also played important roles in the two-year project to install the SODARs. "People across the Lab spent a lot of time working together to deal with all the twists and turns that arose," Thorson says. In the end, he says, the project came in on-time and under budget, and is now producing the results expected by the design team.

Michelle Donovan, staff director of the task force, and LBL Director Charles Shank looked on. Formed by Energy Secretary Hazel O'Leary, the Galvin Task Force is currently touring DOE's nine multipurpose laboratories and will submit a report, expected in early 1995, charting the future of the national labs. In addition to the ALS, the group visited the National Center for Electron Microscopy and the Life Sciences facilities at Bldg. 74.

Secretary O'Leary to speak at LBL

The Secretary of Energy's office has announced plans for Secretary Hazel O'Leary to speak to Lab employees at 12:30 p.m. on Thursday, June 30. O'Leary will be at LBL to attend DOE's quarterly Lab Directors' Meeting and the Secretary of Energy's Advisory Board Meeting. Details, including confirmation of the plans and location of the talk, will be announced as soon as possible.

Technical employees to vote on union

The University Professional and Technical Employees (UPTE) union currently is campaigning to represent a broad cross-section of employees within the University of California system.

Beginning October 17, approximately 3,800 UC "technical unit" employees including 322 from LBL will vote by mail on whether UPTE will exclusively represent them.

In response, Lab management has begun an informational campaign, setting up a Labor Relations Steering Committee. The committee is chaired by Ben Feinberg, the head of operations at the Advanced Light Source.

Feinberg said in addition to seeking representation of the technical unit employees, UPTE also is soliciting signatures on authorization cards from two other employee units in the UC system.

Collecting signed authorization cards is the first step toward union representation. Under the law, such cards demonstrate whether there is sufficient showing of interest to call for a vote by employees for union representation, or even whether an election is necessary.

If 30 percent or more of the individuals in a unit sign authorization cards, then an election is required. If the union obtains signed authorization cards from more than 50 percent of the individuals in a unit, then UPTE may demand the right to become the exclusive representative for all employees in the unit without the need for a formal election, subject to approval by the state's Public Employee Relations Board (PERB).

Feinberg said in the months ahead, both Laboratory management and UPTE will be communicating with employees about union representation.

As required by the law, LBL has given UPTE the laboratory addresses of employees in the targeted units, allowing the union an opportunity to communicate with these employees. Feinberg said that the Labor Relations Steering Committee will mount an educational campaign, meeting with employees and answering their questions.

Siminovitch and Zhang were recognized for their work on energy-saving venting systems for compact fluorescent lights. Siminovitch was recently named 1994 Energy Engineer of the Year by the Association of Energy Engineers for his research on lighting. Alex Pines of Materials Sciences also won an FLC award this year for his work on nuclear magnetic resonance.

Gay pride month: Mother and father to speak on family issues

Charles and Margaret Jackson, representatives of the Oakland/East Bay Chapter of P-FLAG (Parents, Family and Friends of Lesbians and Gays), will speak at noon on Thursday, June 30, in the Bldg. 50 auditorium. Their talk on "Coming Out: Issues of Loss, Grief, Acceptance, and Unconditional Love" will follow a short video presentation of "The Unexpected Journey," a documentary about the experiences of families who must deal with a family member's homosexuality.

Margaret Jackson, who has an M.A. in Spanish, teaches Spanish by correspondence for UC Berkeley Extension. Charles Jackson, who has a B.A. in International Relations, is a self-employed real property appraiser and financial plans advisor.

The Jacksons became active members of P-FLAG a decade ago, following their son's revelation that he was gay. In addition to finding the initial support, understanding, and answers they needed, P-FLAG provided them with an opportunity to help educate others about homosexuality and family issues. Like the Jacksons, other P-FLAG members frequently speak to schools, churches, and other community groups in an effort to work for human rights and respect for their daughters and sons.

The event is the last of the Gay Pride Month activities, which have been organized by the Lesbian, Gay and Bisexual Association.

Patent Department: In answer to your question...

From time to time, the attorneys and patent agents in LBL's Patent Department receive questions from individual researchers, the answers to which may be of interest to others in the Laboratory. If you have questions for the Patent Department, call X7058.

Q: Which LBL division files the most invention disclosures?

A: The Energy and Environment Division leads the Lab in invention disclosures filed since May, 1991, with the Materials Sciences Division a close second, according to Paul Martin, manager of the Patent Department. A total of 174 disclosures have been filed in the past three years at LBL, with every division filing at least one invention disclosure.

The totals by division are as follows: Energy and Environment, 42; Materials Sciences, 37; Life Sciences, 25; Accelerator and Fusion Research, 23; Engineering, 16; Physics, 11; Earth Sciences, 5; Energy and Chemical Sciences, 4; Information and Computing Sciences, 4; Nuclear Science, 4; Environment, Health and Safety, 2; Structural Biology, 1.

Protection for PCs

Students and visiting scholars that come to the Lab every summer can unwittingly bring with them computer viruses, so now is a good time to make sure Lab computers are protected. (The PC Support Program detected several severe PC viruses earlier this spring.)

PC users can defend their systems from invaders with Data Physician Plus, a virus protection program provided by DOE. Version 4.0C of Data Physician Plus is available on the ICSD_NOV1 Novell Server.

Novell clients can request the software with the following DOS procedure:

F:\> login icsd_nov1/guest <carriage return>

F:\> z: <carriage return>

Z:\> cd dataphy.40c <carriage return>

Users should copy all files to a new directory on their hard drive, then log off the server.

PC users who are not Novell clients may request Data Physician Plus from the PC Support Program at X6858.

Site license for Macs

The UC Office of the President has negotiated with Apple Computer for a site license that provides Macintosh users at all of the UC campuses and the three DOE Laboratories with the latest system software (System 7.1+), TCP/IP network connectivity and MacX software.

The software may be copied from the Appleshare server at WKSGServer located in the wksg-50b zone. For more information call the Computing Services Macintosh Support hotline at X6900.

Parking enforcement stepped up

Two of the most congested parking areas at the Lab--the lots in front of Bldg. 50 and around Bldg. 90--will have their parking enforcement increased beginning Monday, June 27. Both areas are reserved for Blue Triangle, Director's and Special Reserved parking permits (which includes disabled permits).

The Bldg. 90 lot has been especially crowded lately because of the seismic upgrade underway. Fred Lothrop, manager of Parking Services, encourages everyone who can park away from Bldg. 90 and use the shuttle bus to do so.

Officers will be issuing warning tickets, orders to show cause, and standard citations for violations of LBL parking policy. Violators of DMV codes will be issued citations with corresponding fines.

Employees with questions may call Lothrop at X7726 or David Wright at X5196.
