Norwegian EUROTRAC Participation 1986-1990.
Hov, Øystein; Stordal, Frode; Schmidbauer, Norbert; Hermansen, Ove; Braathen, Geir Ole; Pacyna, Jozef M; Nielsen, Claus; Isaksen, Ivar S A; Berntsen, Terje; Jonson, Jan Eyof; Berge, Erik; Flatøy, Frode (NILU OR;17/91, Research report, 1991)The Norwegian scientific participation in the Eureka project EUROTRAC 1986-1990 is documented in the report. The main Norwegian activity is centered within TOR (Tropospheric Ozone Research) where measurements are carried. ... -
OKSIDANTDANNELSE I FORBINDELSE MED UTSLIPP FRA BRENNING AV NATURGASS PÅ OLJEFELTENE I NORDSJØEN.
Hov, Øystein (NILU OR; 8/86, Research report, 1986)Det er gjort et overslag som viser at utslippene av ikke-metan hydrokarboner og nitrogenoksider i forbindelse med brenning av gass i fakler i Nordsjøen, sannsynligvis er så små at det er liten mulighet for nevneverdig ... -
OMSETNING AV SVOVEL OG NITROGEN I ATMOSFÆREN
Jerre, Jon; Hov, Øystein; Isaksen, Ivar S A (NILU OR; 16/83, Research report, 1983)Det er undersøkt hvordan forandringer av engelske utslipp av svoveldioksyd, nitrogenoksyder og hydrokarboner kan påvirke avsetningen av svovel og nitrogenkomponenter over Sør-Skandinavia. Beregningene viser at en 25% ... -
OZONE IN THE TROPOSPHERE
Hov, Øystein (NILU TR;10/83, Research report, 1983) -
PHOTOCHEMICAL OXIDANT CONTROL STRATEGIES IN EUROPE: A 19 DAYS' CASE STUDY USING A LAGRANGIAN MODEL WITH CHEMISTRY.
Hov, Øystein; Stordal, Frode; Eliassen, Anton (NILU TR; 5/85, Research report, 1985)The trajectory model with atmospheric chemistry developed by NILU, University of Oslo and DNMI (EMEP) has been applied to calculate the oxidant concentration at 9 receptor points in South Scandinavia in the period 26 August ... -
PROSJEKTERING AV ATMOSFÆREKJEMISK FORSKNINGSSTASJON I NY-ÅLESUND PÅ SVALBARD
Hov, Øystein; Holtet, Jan A. (NILU OR; 67/87, Research report, 1987)Forprosjektering av en ny renluftstasjon i Ny-Ålesund viser at det beste er å etablere en ny stasjon på Zeppelinfjellet 475 m o.h., med gondolheis ned til Badehuset. Etablering av heis og stasjon regnes å koste ca. 8 ... -
REVIEW OF PAPERS PUBLISHED IN 1985 ABOUT EMISSION, TRANSPORT, TRANSFORMATION AND DEPOSITION OF ATMOSPHERIC TRACE CONSTITUENTS OF IMPORTANCE FOR ACID DEPOSITION.
Hov, Øystein (NILU TR;3/86, Research report, 1986)About 300 papers published in 1985 or late in 1984 have been reviewed. There has been progress in the development of models for acid deposition and photochemical oxidants. Simultaneous measurements of O3, NOx, individual ... -
SO2-utslipp i ulike norske landsdeler og deres betydning for forsuring i Norge.
Hov, Øystein (NILU OR; 5/89, Research report, 1989)En modell er utviklet der sannsynligheten for at SO2-utslipp fra norske EMEP-ruter skal avsettes i utvalgte resipientområder. Beregningene viser at bare 1-2% av totalavsetningen av svovel i Øst-Finnmark og Aust-Agder skyldes ... -
STREET CANYON CONCENTRATIONS OF NITROGEN DIOXIDE IN OSLO, MEASUREMENTS AND MODEL CALCULATIONS
Hov, Øystein; Larssen, Steinar (NILU OR; 4/82, Research report, 1982)Nitrogen dioxide in the concentration ranges measured in a street canyon in Oslo in January 1981 (up to 300 ppb) is explained by a combination of mixing with aloft air, the reactions NO+O3→NO2+O2 and NO+NO+O2→NO2+NO2, and ... -
THE ABATEMENT OF PHOTOCHEMICAL OXIDANTS IN EUROPE. CALCULATIONS IN THE SUPPORT OF OECD'S PROJECT "CONTROL OF MAJOR AIR POLLUTANTS."
Hov, Øystein (NILU OR; 72/87, Research report, 1987)The Norwegian lagrangian long-range transport model with CBM-X chemistry has been applied to calculate the concentration of ozone and other photo-chemical oxidants at 14 measuring sites in Europe 1-7 June 1982. Reduction ... -
The relationships between photochemical oxidant episodes, acid deposition and global atmospheric change, and emission changes of nitrogen oxides and volatile organic compounds.
Hov, Øystein (NILU OR; 12/88, Research report, 1988)The effect of a reduction in NOx and VOC emmisions on ozone in photochemical oxidant episodes, on acid deposition and long term global atmospheric change, is reviewed. -
Tropospheric ozone depletion in the Arctic during spring. Measurements on the Zeppelin Mountain on Spitsbergen.
Solberg, Sverre; Hermansen, Ove; Joranger, Einar; Schmidbauer, Norbert; Stordal, Frode; Hov, Øystein (NILU OR;27/94, Research report, 1994)This report presents measurements of ozone, non-methane hydrocarbons, sulphate, ammonium, halocarbon and meteorological parameters from Spitsbergen in the Arctic. The focus is the rapid depletion of surface ozone in spring. ...
