TL;DR: In this article, the authors present the major aspects of this methodology and a framework for conformance testing of Open Systems Interconnection (OSI) services and protocols, and present a methodology and framework for OSI conformance test suites.
Abstract: Now that many international standards for Open Systems Interconnection (OSI) services and protocols have reached at least the Draft International Standard stage, there is much international activity in standardizing OSI conformance test suites. This new activity is based on the emerging OSI conformance testing methodology and framework standards being progressed by ISO and CCITT. This paper presents the major aspects of this methodology and framework.

TL;DR: In this article, surface ozone has been measured over New Delhi, an urban site, a region of intensive anthropogenic activity since 1997, and the hourly averaged surface ozone data illustrates that on a large number of days the surface ozone values at Delhi exceed the World Health Organization (WHO) ambient air quality standards (hourly average of 80 ppb) for ozone.
Abstract: Surface ozone has been measured over New Delhi, an urban site, a region of intensive anthropogenic activity since 1997. Seasonal variations in ozone concentration show pronounced maxima in the summer and autumn seasons and minima in monsoon and winter seasons. Diurnal patterns in ozone concentration show daytime in situ photochemical production throughout the year. The high ozone episode days were associated with meteorological parameters such as sunny and warm weather, stagnant wind patterns and low relative humidity. The monthly average maximum concentration in summer was found to be in the range of 62–95 ppb whereas, it was found to be 50–82 ppb in the autumn (October and November). The analysis of hourly averaged surface ozone data illustrates that on a large number of days the surface ozone values at Delhi exceed the World Health Organization (WHO) ambient air quality standards (hourly average of 80 ppb) for ozone. On some occasions, night‐time increases of surface ozone concentration have been obser...
