The compilation and archiving of NOx and NOy measurements began in

when Dr. Louisa Emmons arrived at the University of Michigan. Details

the format of the data files decided upon, archive policy and the data se_:

the submission of the first report, data summaries have been obtained for

STRATOZ III, OCTA and TOR/Schauinsland campaigns, and the full data part of this archive in the near future.

Climatologies of NOx and NOy have been developed from these and pz

data sets, including the available GTE campaigns (ABLE-2A,B, -3A,B, CI_

A, PEM WEST-A) and AASE 1 and 2. The data have been grouped by sc

(boundary layer and 3 km ranges in the free troposphere). Maps showing

midday NO, NO: and NOy have been produced for each season for the bc

3 km ranges of the free troposphere. The statistics of the data (median, m

deviation, central 67% and 90%) have also been determined, and are shown

figures included here. Figure 1 shows the statistics for the Boundary Laye

ground sites and aircraft measurements below 0.5 km) for midday NO, N(:

a map showing the location of the data. Similarly, Figure 2 shows the dis

3-6 km layer. Similar analyses have been made for any ozone and CO dat_:in these data sets.

Since the Year 1 summary report of this project two talks on the archive

The climatologies that have been compiled from the newly archived data,

archived data sets, were presented at the AEAP Annual Meeting in Vir_

April 23-28, 1995. The abstract for this meeting is attached. We were also i

these results at the Combined IGAC Meeting: GIM/GEIA/GLOCHEM, in

6-8, 1995. A copy of the viewgraphs shown there are also attached. The

that was written, announcing the availability of the archive, is expected tc

the end of Dec. 1995. The final version is included here.

In completion of this project we are preparing a manuscript for publicat

issue on AERONOX in Atmospheric Environment presenting these climNOx and NOy. Comparison will be made to results from several chemic.

including GFDL (H. Levy), Lawrence Livermore (C. Atherton), NCAR (G.
