Book Description
The potential of molecular fluorescence was assessed as a stratospheric monitor of the concentrations of various minor species. Seventeen molecules were considered and all spectral regions from the vacuum ultraviolet through to the infrared are included. The exercise has produced few surprises; however, further confirmation has emerged as to the feasibility of this sensitive technique for monitoring stratospheric OH, NO2, and SO2, sufficient to warrant its development as analytical flight hardware for these species. All the other molecules have been eliminated with the exception of C10 which appears to have promise but requires additional information before its detection limit can be calculated; its fluorescence spectrum is as yet uninvestigated. A handbook for molecular fluorescence is presented, and a compilation of all reported studies for simple molecules using line source excitation is included.

Carbon Cycles and Climate
Author: Jerry S. Olson
Publisher:
ISBN:
Category : Carbon cycle (Biogeochemistry)
Languages : en
Pages : 260
Book Description
This partially annotated bibliography contains the first 1000 references from a computerized file of literature on the global ecological implications of carbon cycles and climatic changes. Many early citations originated from the Biogeochemical Ecological Information Center established at Oak Ridge National Laboratory in 1968 and from profiles of computerized files such as Government Research Abstracts (GRA) and Biological Abstracts (BA). Later citations have been extracted from the open literature through 1978 and early 1979, from government reports and impact statements, and from profiles of GRA, BA, and the Energy Data Base of the Department of Energy Technical Information Center, Oak Ridge, Tennessee. The subject categories covered by this bibliography may be divided into two main topics: carbon cycling and climate system analysis. Volume I contains an introduction and overview. Volume 2 contains an alphabetical (by author) listing of citations. Volume 3 provides indexes for author, organization (corporate authority), keywords (or free index terms), taxonomic category, subject category, Chemical Abstracts codes, Biological Abstracts codes (crosscode), and COSATI/Weekly Government Abstracts codes concentrated with permuted title words.
