44,041 | National air quality and emissions trends report, 1992 | null | 1,993 | The analyses in the report focus on comparisons with the primary standards in effect in 1992 to examine changes in air pollution levels over time, and to summarize current air pollution status. The first three chapters of the report cover trends in the six pollutants with National Ambient Air Quality Standards. Chapter... | 0 |
52,170 | The relationship between anthropogenic nitrogen oxides and ozone trends in the Arctic troposphere | Jaffe, DA | 1,993 | INTRODUCTION Low solar insolation and low precipitation rates dramatically slow down the oxidation and removal of many anthropogenic pollutants in the Arctic, including hydrocarbons and nitrogen oxides. These processes give rise to a seasonal pollutan | 0 |

48,211 | Convective parameterization in mesoscale models: the Kain-Fritsch scheme | Kain, JS; Fritsch, JM | 1,993 | 16.1. Introduction The Kain-Fritsch (1(F) convective parameterization scheme (CPS) is based on the same fundamental closure assumption as the Fritsch-Chappell (FC) (1980) scheme-convective effects are assumed to remove convective available potential energy in a grid element within an advective time period.
