A -- SCIENTIFIC INVESTIGATIONS IN THE EARTH SCIENCES DISCIPLINE OF PRECIPITATION SCIENCE AND RELATED TROPICAL ENERGETICS IN CONNECTION WITH THE TROPICAL RAINFALL MEASURING MISSION (TRMM) SOL NRA-98-MTPE-02 DUE 052698 POC Ramesh Kakar, TRMM Program Scientist, Phone (202) 358-0240, Fax (202) 358-2770, Email Ramesh.Kakar@hq.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/HQ/date.html#NRA-98-MTPE-02. E-MAIL: Ramesh Kakar, Ramesh.Kakar@hq.nasa.gov. The previous synopsis for this NASA Research Annoucement, posted on 3/2/98, is revised by correcting the solicitation number to read "NRA-98-OES-02." The following text remains unchanged. The National Aeronautics and Space Administration (NASA) announces the solicitation of research proposals to conduct scientific investigations in the Earth sciences discipline of precipitation science and related tropical energetics in connection with the Tropical Rainfall Measuring Mission (TRMM) launched in November 1997. This opportunity, which follows an earlier TRMM research announcement that began in 1997, is intended to support TRMM post-launch investigations for a 3-year period. Five tropics of interest are emphasized in this NRA that are relevant to TRMM post-launch science investigations: (1) algorithm improvement, (2) data utilization, (3) validation data, (4) field campaigns, and (5) applications. The NRA will be available electronically on the release date, via the Internet at the Earth Science Enterprise''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. A paper copy will be available to those who do not have access to Internet by calling (202) 358-3552 and leaving a voice mail message. This announcement will be open for the period from March 20, 1998 through May 26, 1998, and proposals may be submitted at any time throughout that period. (0065)
