A -- ATMOSPHERIC CHEMISTRY MODELING AND ANALYSIS, NRA-97-MTPE-07 SOL NRA-97-MTPE-07 DUE 081597 POC Dr. Jack Kaye, A.C.M.A.P. Manager/T.O.M.S. Program Scientist, Phone (202) 358-0757, Fax (202) 358-2770, Email Jack.Kaye@hq.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/HQ/date.html#NRA-97-MTPE-07. E-MAIL: Dr. Jack Kaye, Jack.Kaye@hq.nasa.gov. The National Aeronautics and Space Administration (NASA) intends to solicit research proposals for science investigations to be carried out as part of the Atmospheric Chemistry Modeling and Analysis Program (ACMAP) of the Science Division of NASA's Office of Mission to Planet Earth. Proposals for membership in a newly reconstituted science team for the Total Ozone Mapping Spectrometer (TOMS) series of satellite instruments are also solicited with this announcement. ACMAP supports research in computational modeling and data analysis for studies on the trace constituent distributions of the troposphere and stratosphere, as well as dynamical properties of the stratosphere, emphasizing large regional and global scales. Component parts of ACMAP include (1) Stratospheric Dynamics and Related Data Analysis: (2) Atmospheric Chemistry Data Analysis; (3) Aerosols, Stratospheric Clouds, and Radiation; (4) Multi- Dimensional Atmospheric Modeling. New proposals, as well as renewal proposals for expiring tasks, are desired for all of these areas, although the area most likely to receive increased funding in response to this solicitation is the use of atmospheric models to infer information about production and destruction of chemically active trace constituents at the Earth s surface. The TOMS science team will support activities in seven areas: (1) validation, including limited field observations to be done specifically for the purpose of validating data products obtained by TOMS; (2) ozone trend studies, including comparison with existing ground-based networks; (3) algorithm improvement; (4) tropospheric aerosol studies (5) tropospheric ozone data product generation and analysis; (6) surface ultraviolet radiation studies and comparison with ground-based measurements; and (7) applications, especially those for tropospheric meteorology, hazard avoidance, and smoke/particle detection. This solicitation is open to all categories of organizations, foreign and domestic. A copy of this solicitation is available over the Internet via the Mission to Planet Earth Home Page at http://www.hq.nasa.gov/office/mtpe under MTPE Research Announcements or via anonymous ftp at ftp.hq.nasa.gov/pub/mtpe. Paper copies of the NRA will be available to those who do not have access to the Internet by calling (202) 358-3552 and leaving a voice mail message, including full name and address, including zip code, and telephone number, including area code. This announcement will be open for the period from May 16, 1997 through August 15, 1997 and proposals may be submitted at any time throughout that period. Letters of intent are requested but not required; such letters should be submitted by June 27, 1997.
