-The intensive field phase of the summer collo-

quium on tropospheric photochemistry draws to a closetoday. For the past two weeks, about 30 participantshave been measuring trace chemicals and meteorologicalparameters at a site in the Pawnee Grasslands innortheastern Colorado (see Staff Notes, 23 May). The

S participants have come from 11 universities, NASA, andthe National Oceanic and Atmospheric Administration aswell as from NCAR.

According to colloquium organizer Anthony Delanyof the Atmospheric Quality Division, the first phasehas gone well. "We've had several good days of mea-surements," he says. "In fact, last Thursday andFriday [5 and 6 June] conditions were ideal for mea-suring fluxes of trace gases: the atmosphere was wellmixed, and the pollution that was present was uniformlydistributed."

Most of the instruments, including the airborneozone and air-motion sensing systems, have worked suc-cessfully. The raw data have not yet been convertedinto the desired quantities. Fluxes, for example, arenot measured directly; they are computed from gradients(measurements of concentrations at successive heights)and from turbulent diffusion information calculatedfrom micrometeorological measurements. But it isalready clear that the experimenters have obtainedsignificant gradients for ozone, oxides of nitrogen(NOx), nitric acid, and hydrogen peroxide.

In addition to the usual daytime observations ofchemical reactions involving light, the participantsmade continuous measurements during one 24 h periodthis week. They conducted this special experiment

because some constituents produced photochemically lastas long as a couple of days, and a few persist forseveral weeks. These substances continue to interact,even at night. The set of around-the-clock measure-ments will help establish a more complete understandingof the daily cycle.

Meanwhile, James Kasting (an Advanced Study Pro-gram postdoctoral fellow) and a group of students havebeen refining and debugging two models of photochemicalprocesses. The first, a zero-dimensional model, usesmeasured values of long-lived atmospheric species topredict the amounts of short-lived species that will bepresent at photochemical equilibrium. The experimenterswill compare the model's predictions with the measure-ments of short-lived species being made in the field.The second model is a one-dimensional model that takesboth vertical diffusion and chemical reactions intoaccount. With it the scientists can run experimentsthat begin with quantities measured in the boundarylayer and investigate their effect on the rest of thetroposphere. As data from the Grasslands becomeavailable, the modelers will undertake such studiesfor the colloquium experiment.

Each day a group of seminars will address one offive topics: boundary-layer meteorology, thephotochemistry of the troposphere, the chemical andmicrometeorological instrumentation used in thefield phase, laboratory measurements of speciescollected in the field, and the models of photostatesand removal fluxes for atmospheric constituents.The colloquium organizers note that everyone is wel-come to attend the seminars.

ANNOUNCEMENTS

SUMMER VISITORS RECEPTION

UCAR will host a reception for summer visitorson Wednesday, 25 June. The activities will begin at4:00 p.m. in the Mesa Laboratory lobby with a concertby the Centennial Brass Quintet, whom many staff mem-bers will remember for their outstanding concerts atNCAR and elsewhere in the area. The members of thequintet are David Fulker, trumpet (NCAR ComputingFacility); Robert Lenicheck, trumpet; Robert Murray,French horn; Bruce Lazier, trombone; and Eric Ronneberg,tuba. Refreshments will be served in the cafeteriafollowing the concert (at about 4:45 p.m.). All NCARstaff members and visitors are invited to attend andwelcome the summer visitors as well as renew NCARacquaintances.

11TH ANNUAL NCAR GOLF CLASSIC

The 11th annual NCAR Golf Classic will take placethis year on Friday, 27 June, at 9:00 a.m. at theLake Valley Golf Course. Registration forms for the18-hole tournament have been distributed to the staff.If you did not receive one and wish to participate,contact Wray Freiboth, ML room 202A (ext. 236). Com-pleted forms are due to him by Friday, 20 June.

LUNCHEON WINNER

Each week a free lunch is awarded to the personwhose name is drawn from a fishbowl of signed lunchreceipts in the Mesa Lab cafeteria. The free lunchmust be collected within a week of the Tuesday draw-ing. The winner's name will be posted in thecafeteria above the bowl, and will also appear inStaff Notes (on Friday) as a reminder.
