"Ozone Trends Deduced from Combined Nimbus 7 SBUV and NOAA 11 SBUV/2 Data," S.M. Hollandsworth (NASA-Goddard, Greenbelt MD 20771), R.D. McPeters et al., Geophys. Res. Lett., 22(8), 905-908, Apr. 15, 1995.

Extends the Nimbus-7 SBUV measurements of global ozone (Nov. 1978-June 1990) through June 1994 using measurements from the NOAA-11 SBUV/2. In the tropical middle stratosphere and in the upper stratosphere at mid-latitudes, trends through June 1994 are 1.5-2% per decade less negative than through June 1990. In the lower stratosphere, trends are nearly 1.5% per decade more negative in the Southern Hemisphere tropical regions, but are relatively unchanged elsewhere.

"Stratospheric Ozone Depletion—An Overview of the Scientific Debate," F. Drake (Sch. Geog., Univ. Leeds, Leeds LS2 9JT, UK), Prog. Phys. Geog., 19(1), 1-17, Mar. 1995.

Gives a detailed account of the development scientific understanding of anthropogenic influences on the ozone layer, starting with concern over supersonic aircraft emissions around 1970.

Item #d95may30

"Atmospheric Methyl Bromide (CH3Br) from Agricultural Soil Fumigations," K. Yagi (Natl. Inst. Agro-Environ. Sci., Tsukuba, Ibaraki 305, Japan), J. Williams et al., Science, 267(5206), 1979-1981, Mar. 31, 1995.

After seven days of field fumigation, 34% of the applied methyl bromide had escaped into the atmosphere. Comparison with an earlier experiment, in which the amount of escape was greater, showed that higher soil pH, organic content and moisture, and deeper, more uniform injection of methyl bromide may in combination reduce the escape.
