1. INTRODUCTION

The National Space Development Agency of Japan (NASDA) hereby announces the solicitation of research proposals to conduct scientific investigations in precipitation science and related tropical energetics in connection with the Tropical Rainfall Measuring Mission (TRMM) satellite launched in November 1997. TRMM's goal is to provide useful information on atmospheric heating, which drives the general circulation in the atmosphere, by estimating monthly rainfall using TRMM sensors; the Precipitation Radar (PR), the TRMM Microwave Imager (TMI) and the Visible/Infrared Scanner (VIRS). To achieve this goal, algorithms to estimate rainfall have been developed and revised. The new reprocessed datasets will be produced with the latest Version 6 algorithms in the near future. Aside from the algorithms, various researches on climate have been performed, including the trend analysis and precipitation statistics. Also the air-sea interaction and hydrological studies have been carried out. It is expected that further progress in understanding precipitation characteristics will, for example, enable us to estimate the latent heating profile in the tropics, which is one of the main objectives in the TRMM project. In the application field, new researches using the TRMM data, such as agricultural and fishery applications, have started. Since the lifetime of the TRMM satellite seems to be extended for some more years, it is expected that further useful data will be accumulated.

NASDA is therefore soliciting research proposals to promote utilization of the TRMM data for understanding the distribution and variation of tropical/extratropical rainfall and applying them to new scientific areas. Please note that any algorithm-related proposals are not covered in this Research Announcement (RA). Proposals are sought for new and continuing research associated with TRMM. This opportunity, which follows the third TRMM RA in 2001, is intended to support subsequent science investigations for the three-year period beginning in April 2004. NASDA will spend approximately 10 million yen during fiscal year 2004 for proposed activities of 7-10 new Principal Investigators (PIs). However, it should be noted that the budget allocated for the new PIs' activities after fiscal year 2004 may change substantially depending on NASDA's budget situation.

Participation in this program is open to all categories of domestic and foreign organizations, including educational institutions, industry, non-profit institutions, and Japanese Government agencies. In accordance with NASDA policy, all investigations by foreign participants will be conducted without any exchange of funds, that is, investigators whose home institutions are outside Japan cannot be funded by NASDA. Proposals may be submitted at any time until September 30, 2003. NASDA reserves the right to consider proposals received after that date if in accordance with section 3-8, that is, "the selecting official deems the late proposals to offer significant scientific and/or technical advantage or cost reduction." Proposals submitted to NASDA will be evaluated through a scientific peer review. Selection is expected to be announced in January 2004.

All proposers are strongly encouraged to submit a letter of intent (see section 5) to respond to this Announcement by August 29, 2003.

(*)NASDA will be reborn as the Japan Aerospace Exploration Agency(NASDA) on October 1, 2003.

2. TECHNICAL DESCRIPTIONS

The first and second Research Announcements (RAs) focused mainly on "Algorithm Development" and "Calibration and Validation" for the Precipitation Radar (PR). The third RA was on sophisticated algorithm developments and modeling/data analysis. Under the previous RAs, we could broaden the research area and expand users of the TRMM data. In the fourth RA, to broaden the research area is required further to explore new scientific and public applications.

By taking advantage of PR's unique ability to measure not only the horizontal distribution of rain but also its vertical structure, scientific results relevant to precipitation distribution and variation have been obtained. Such important achievements include the study of the diurnal variations of cloud and precipitation and the study of the distribution of shallow convection over the ocean. More than five years of TRMM data have now been accumulated. This RA thus strongly encourages scientific climatological analysis of the rain distribution, structure and variation. The analysis may use not only TRMM data but also other satellite data and/or objective analysis data.

Advanced studies of TRMM data applications are also encouraged. Assimilation of TRMM data is an example. Applications could be extended to studies of properties other than rain. For example, agricultural application, hydrological application or fishery application etc. Such research that explores a new application of satellite data is highly encouraged.

The proposer should keep in mind that, unlike the previous RAs, NASDA will not support any algorithm development in this RA. The proposer should also keep in mind that NASDA is not a general funding body for the scientific community. This RA seeks to accomplish TRMM's goal and to expand new utilization of TRMM data. The proposal should describe plans for TRMM data usage well.

Several specific examples of research fields sought by this RA are given below.
- Estimation of atmospheric heating profiles by TRMM data.
- Long-term monitoring study of the global water cycle.
- Data assimilation study for TRMM data.
- New application study to estimate physical characteristics other than rain from TRMM data.
