Title: Application of IR remote sensing technology for monitoring of intersection CO concentrations in Albuquerque, New Mexico

Abstract

This paper reports the preliminary testing of an infrared (IR) remote sensor (GASCOFIL) for the detection of carbon monoxide (CO) concentrations near the intersection of San Mateo Drive and Menaul Drive in Albuquerque, New Mexico on May 11, 1993. The goal of this test was to demonstrate the effectiveness of GASCOFIL as an in-situ monitor for studying the time dependent distribution of CO at intersections. In order to measure the concentration of CO, the sensor viewed a crossroad path seven feet above Menaul Drive three hundred and fifty feet from the center of San Mateo Drive. The sensor was positioned ten feet from a gas and aerosol-monitoring station equipped with an EPA approved point CO monitor. GASCOFIL produced real time data that showed variations in CO levels that correlated with traffic light cycles. Variations in the CO concentration due to individual vehicles were also recorded. A two hour average of the GASCOFIL CO concentration data taken through rush hour was six percent lower than CO data taken from an EPA point sensor adjacent to the intersection. The small percentage variance between the two averages might be due to the separation and size difference of the sample volumes. GASCOFIL measured variationsmore » and peaks in the CO concentration not seen by the EPA sensor because it had a faster time response and its sample volume was closer to the vehicular sources.« less

  • As we move toward the 21st century, I believe the importance of the ethical system on which the scientific establishment, including the national laboratories, can build its contributions to society is becoming increasingly more important. Issues include the impact of the research we do, the trust we have between ourselves and the general public and the federal government, and the complexity of the problems that we work on. One of the most important roles that I see for research management in large institutions, like the national laboratories, is to create the appropriate environment for ethical behavior for all of itsmore » employees. Ethics and modern science demands that we create and live a set of shared values. As Bob Dynes pointed out this morning, we're not just talking about rules. We really must have values upon which we build and create the kind of behaviors we want to see. The major issue that I see in developing these shared values is that management and employees must jointly develop, socialize and live those shared values. In this session today, as I said, we want to explore the issues of intellectual freedom and ethical environment in government and the contracts under which the national laboratories operate. One of the laboratories is run by a nonprofit, the University of California, and the other is a paid-for-profit corporation. I don't know if there are any differences, depending on who the overseeing contractor is. I don't think there are, but it would be interesting to explore any differences we might see between the two. We have chosen the title 'Intellectual Freedom.' It's not academic freedom. Although, clearly, there are a lot of shared attributes between academic freedom and intellectual freedom. In our case, intellectual freedom allows our researchers to challenge technical decisions that are made by the laboratory, by the government or by their peers in their area of expertise, not in policy making, but in the scientific realm. It really does not permit them the freedom to roam at will outside of their areas of technical expertise into the realm of policy without clearly stating that their remarks are those of a private citizen and must be handled, therefore, outside of the laboratory business. This is a major issue within our laboratories, and I think one that we try to nurture very carefully, because without it, we think that there would be a closing up of laboratories because of the type of classified work that we do. The issues that I hope we might explore in this session include, (1) how do you give technical advice to a policymaker? Where do you draw the line with respect to your judgment, your advice versus your opinion, which can change how government attacks very significant societal problems: (2) The issue of security and classification. How does that affect the intellectual freedom of our staff? (3) Dealing with the public on matters of risk. I am going to add to that, also, dealing with our employees on matters of risk, because one of the things that we're finding as we get better with our detection technology and our screening technologies, we now find out about how employees might be susceptible to illnesses, such as berylliosis, problems with beryllium sensitivity. What ethical issues arise when you now have the ability to learn more about impacts on, not only the public, but your employees as well? We share similar types of problems that Bob Dynes mentioned: conflict of interest, intellectual property questions. And we also have the conflict of interest as an institution. And I'll just mention one--perhaps it could come up in the discussion-is in the past year we had an issue with respect to how the Congress and the Administration handled the Comprehensive Test Ban Treaty. What kind of eihical issues arise in testing on our technical judgment regarding the CTBT versus institutional conflict of interest? Questions were raised. Were the laboratory directors simply protecting budgets or were they speaking out on technical matters in which they believe very strongly? So, I think we have many of these issues that come into play in our jobs every day. The security issues raised in the past year regarding Los Alamos were complicated, in my opinion, because of stories in the media that were not necessarily complete or accurate. They were also Complicated by the actions of the federal government in not allowing certain information to be made public because of ongoing litigation. So, it raised a lot of questions, and I think, in the next 5 to 10 years, the events of the past year or two will actually raise a lot of ethical questions about how people handle classified information, not just at the national laboratories, but in general. Not only the legal issues, but the ethical issues, the values associated with handling classified information.« less

  • In this contribution, the author describes two applications of Fourier Transform Infrared Spectroscopy to the monitoring of atmospheric compounds. Firstly, the author reports FTIR solar spectroscopy measurements carried out at ground level at NCAR and on airplanes employing a spectrometer of 0.06 cm{sup -1} resolution. Sample atmospheric spectra and fitting examples are presented for key species relevant to stratospheric chemistry and global change: ozone (O{sub 3}), a chlorofluorocarbon (CF{sub 2}Cl{sub 2}), a greenhouse gas (N{sub 2}O), HCl, NO and HNO{sub 3}. Secondly, the author briefly describes urban air pollution measurements at an intersection with heavy traffic in Tucson, AZ. Twomore » FTIR spectrometers of 1 cm{sup -1} resolution were employed to carry out long-path open-path measurements of the CO/CO{sub 2} ratio and SF{sub 6}. Two FEAT and two LPUV instruments were employed for ancillary measurements of CO, CO{sub 2}, NO, and aromatic hydrocarbons. Measurements of CO at two heights and a comparison of CO/CO{sub 2} ratios obtained by FEAT exhaust emission and FTIR ambient air measurements are reported.« less
