ACID RAIN IS TARGET OF NEW EXPERIMENT

Acid rain is a problem of increasing severitythat has already had major impacts in the north-eastern United States and northwestern Europe,including the loss of fisheries and changes in someforest ecosystems. The Acid Precipitation Experimentis an effort being planned by Allan Lazrus (NCARAtmospheric Quality Division) and nine colleaguesfrom NCAR, universities, and industry. On Tuesday(29 November), the experimenters held an organiza-tional meeting at NCAR to discuss scientificobjectives and strategies for taking measurements.Acids--both gaseous and particulate--will be mea-sured at ground stations and from aircraft at variouspoints between Denver and the northeastern UnitedStates.

Acid rain is related to increasing emissions ofacid-forming compounds from urban and industrialsources. Acidifying pollutants may be deposited onthe land in both wet and dry forms and can come fromlocal or remote sources; some effects have been notedon a global scale. The problem in the United Statesis most serious in the Northeast because most stormsin that area come from the West, picking up acidsfrom industrialized regions as they travel eastward.

Most research on acid rain has dealt with thecomposition of the precipitation itself. APEX will beamong the first studies in which compounds that deter-mine the acidity of the precipitation will be measured;these data will then be compared with actual changes inprecipitation acidity. The experimenters will also tryto correlate acid concentrations at higher altitudeswith cloud droplet composition. Simultaneous measure-ments will be taken of acidic vapors (nitric acid vaporand hydrochloric acid vapor), acidic aerosols, acidanhydrides (precursors of acids in the atmosphere, suchas sulfur dioxide and nitrogen dioxide), and materialsthat can neutralize acids (ammonia and particulatecarbonates).

Al says, "Sulfuric acid has been thought to be themajor source of acid rain and it is the only acid thathas been measured directly in the troposphere in stud-ies of acid rain. Yet it has been shown that, in thepast ten years, as sulfur emissions have decreased,precipitation acidity has nevertheless increased. Sothere seem to be other sources for the acid rain."Al says that nitric acid is believed to be a majorsource; direct measurements of this compound taken inAPEX may provide verification of this hypothesis.

2/Staff Notes/2 December 1977

Measurements will be taken beginning in the fallof 1978. They will be collected in each seasonbecause the acidity and chemical composition ofprecipitation undergo seasonal changes. The APEXresearchers hope to use one of NCAR's Queen Air air-craft to take samples at cloud base to give anindication of what acids are available for incorpor-ation into cloud droplets and at lower altitudes tosee what acids are available for scavenging by fal-ling raindrops. The flight path would be betweenDenver and New England, and six sampling crosssections about 400 km apart would be made at rightangles to the path.

A seventh sampling cross section would be takenover the Atlantic Ocean, off the northeastern coast,to observe transport of atmospheric acids fromindustrialized areas in the northeastern UnitedStates. Shipboard measurements will be madesimultaneously by John Winchester (Florida StateUniversity). Surface measurements will be obtainedfrom precipitation networks sponsored by the ElectricPower Research Institute, the Department of Energy,and the Department of Agriculture.

The APEX scientists, in addition to Lazrus andWinchester, are Walter Berg [NCAR Advanced StudyProgram (ASP)], John Eaton (Cornell University),Barry Huebert (ASP visitor from Colorado College),C.S. Kiang (NCAR Aerosol Project), Gene Likens(Cornell University), Gene McLaren and Volker Mohnen(Atmospheric Sciences Research Center, State Univer-sity of New York at Albany), and Peter Mueller(Environmental Research Technology, West Lake Village,California).

Sampling acid precipitation is not a new idea forAl or for NCAR. In fact, the National PrecipitationSampling Network that Al managed at NCAR during themid-1960s provided one of the earliest acid precip-itation network records. "More recently," Al says,"we have been measuring acids in stratospheric air.The rapid increase of rainwater acidity during thepast decade makes similar measurements in tropospher-ic air a pressing need." With the data from APEX,the experimenters will be able to formulate maps ofacid constituents in the atmosphere. Al says, "Thesemaps, along with maps of precipitation acidity, shouldprovide the kind of documentation we need to gain anunderstanding of acid rain." * LM

FREDERICK MEADOWS

Staff member Frederick Meadows died on26 November after a lengthy illness. He was 62.Funeral services were held on 30 November at theBerkeley Park Chapel in Denver, and burial was atthe Crown Hill Cemetery in Lakewood.

Fred had been an aircraft mechanic at theResearch Aviation Facility since 1971. His primaryresponsibility was maintenance of NCAR's two QueenAir aircraft. He participated in two major fieldoperations: the Venezuela International Meteorolog-ical and Hydrological Experiment in 1972 and theCoastal Upwelling Experiment in Mauritania, Africa,in 1974.

Fred is survived by his wife Angie; threedaughters: Miriam Loghry of Lakewood, Colorado,and Diane Walsh and Pamela Meadows, both of Casper,Wyoming; and a brother, Charles Meadows of Lakewood.

Donations in Fred's memory may be sent to theAmerican Cancer Society. *

NSF PRESENTATION GIVEN

The annual presentation of NCAR's program tothe director of the National Science Foundationwas made in Washington on 28 November by A. RayChamberlain (Colorado State University), chairmanof the UCAR Board of Trustees; UCAR presidentFrancis Bretherton; NCAR executive director JohnFiror; and Andrew Heymsfield of the NCAR Convective

Storms Division (CSD). After an introduction fromChamberlain, Bretherton and Firor presented long-range plans and budgets for NCAR and the NationalScientific Balloon Facility (NSBF) for fiscal years1980-84, as well as highlights of current activities;and Heymsfield discussed research in CSD on measuringunmixed cores in cumulus updrafts.

John Firor says, "We want to thank the staffmembers who came to the presentation rehearsal fortheir valuable comments, which helped make thebriefing clear and smooth. Various people whoattended it in Washington said it was a comprehen-sive and compelling story about NCAR."

Copies of the five-year plans for NCAR and NSBFare available in the NCAR division offices. *

DELPHI QUESTION AND ANSWERQ. Why the difference between the old UCAR

MatnuaZ section 4-l-11 (section II under Relocation

provision that only exempt employees are eligiblefor being reimbursed for moving expenses. Does itnot cost the same, exempt or not, to move a distanceto accept a job? Is NCAR really an "equal opportu-nity employer?"

(con ntinued)}


A. The July 1977 revision of our relocation* policy changes only the wording, not the intent of

the policy. The wording of the old policy was vagueon this point, so it was rewritten for clarification.

Since the policy was instituted originally,relocation payments have been offered only toexempt personnel. The reasoning behind this canbe traced to recruiting policies. Most nonexemptpositions are recruited from the local five-countymetropolitan area (see UCAR Manua section 4-1-2,attachment 1), while many exempt positions arerecruited nationwide. Moreover, anything less than50 miles is considered within normal commutingdistance.

NCAR is firmly committed to being an affirmativeaction/equal opportunity employer. We do, however,recognize some distinctions between exempt (salaried)and nonexempt (hourly) employees. Within each clas-sification, however, the appropriate policies applyto all individuals. Questions about how personnelare classified may be directed to the wage and salaryunit in the Personnel Office.

SUPPORT SCIENTIST II or III: For the ConvectiveStorms Division to collect, process and analyzemultiple Doppler radar data. The position willinvolve field work (continental United States) 2-3months every two years on the average to assist inthe collection of coordinated multiple Doppler radardata. The processing of data involves detailedexamination of all Doppler radar data and the speci-fication of the various parameters utilized by theprocessing software. Individual is expected toparticipate in the analysis phase, working withothers to provide a coordinated study of convectivestorms. Requirements: MS degree in meteorologyplus a minimum of 3 years experience in collectionand analysis of meteorological data with some ofthat data being radar data. Experience with Dopplerradar data is highly desirable. Additional experi-ence may be substituted for education. Anticipatedhire-in salary: $14,300-21,650/year. This position
