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 earlier TRMM research announcements in 1997 and 1998, is intended to support TRMM related investigations for a 3-year period in two areas. The first area is to continue and enhance existing investigations related to algorithm development, validation, and applications. The second area of emphasis deals with the analysis of TRMM validation data collected during five Field Experiments. Participation in this program is open to all categories of domestic and foreign organizations, including educational institutions, industry, non-profit institutions, NASA centers, and other U.S. agencies. In accordance with NASA policy, all investigations by foreign participants will be conducted without any exchange of funds. The interested reader may find more information regarding current TRMM research at the TRMM Web page (http://trmm.gsfc.nasa.gov). The NRA will be available electronically on the release date, via the Internet at the Earth Science Enterprise ''Home Page'' at ''http://www.earth.nasa.gov'' under ''Research Opportunities'' or via anonymous ftp at ftp.hq.nasa.gov/pub/ese. 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 July 21, 1999 through October 4, 1999, and proposals may be submitted at any time throughout that period.
