摘要:
Members of Congress have recently expressed their concern over a possible gap in weather satellite data resulting from the flawed GOES (Geostationary Operational Environmental Satellites) program. They looked into options to supplement data in the event that GOES‐7 fails before the scheduled launch of GOES‐I in December 1992. GOES‐7 is currently the only geostationary weather satellite in orbit. GOES‐I is the first of in the GOES‐Next (next generation) series, which will carry improved instrumentation and will be part of the modernization of the National Weather ServiceAt a joint hearing between the House subcommittee on the Environment and the subcommittee on Investigations and Oversight held July 25, members heard testimony on factors contributing to the GOES‐NEXT problems, current technical status of the program, and options to help avoid a gap in data. The General Accounting Office also released a report that investigated the cost, schedule, technical status, reasons of cost increases and delays, and options to avoid the data gap. A Senate subcommittee heard testimony on the flawed proj

摘要:
Carbon monoxide, an atmospheric gas that plays an important role in the chemical interactions involved in the global greenhouse effect, may have been underestimated by as much as 25% in some studies, according to a paper published in theJournal of Geophysical Research(vol. 96, D7, July 20, 1991).Paul C. Novelli and L. Paul Steele of the University of Colorado and James W. Elkins of NOAA developed a series of carbon monoxide reference mixtures for use in the calibration of measurements of atmospheric concentrations of CO. They compared various existing CO reference gases from the National Institute of Standards and Technology (NIST) and the Commonwealth Scientific and Industrial Research Organization (CSIRO), whose standards were referenced to those maintained by the Oregon Graduate Institute for Science and Technology (OGIST).

摘要:
In reading S. Fred Singer's comments in Forum (Eos, May 21, 1991) on the earlier letter by Kaula and Anderson on AGU's proper role in society (Eos, April 9, 1991), I find myself entirely in agreement with his admonition that AGU positions, in this case specifically on global warming, must add “a certain amount of political sophistication.” But while I cannot disagree with the view that geophysicists should confine their advice to matters in which they have expertise, I also wonder if any of us deserves criticism when, noting the difficulty political leaders have in connecting causes with effects, we yield occasionally to the temptation to stray beyond mere facts and spell out potentially unfavorable connections. Early linking of complex but subtly related phenomena is one of the areas in which we have some credibility, is it not?Even as scientists we are, after all, compelled to share destinies with the other passengers crammed into the stairwells of the national vehicle, a bus tailgating an oil tanker careening right and left at high speed down the global highway, driven by a crew of politicians drunk on paleozoic distillate and trained in the Alfred E. Newman College of Navigation, where the principal graduation requirement is an intense desire to sit in front and st
