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) 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 to provide instantaneous rain rates and monthly total rainfalls. Before the TRMM launch, there were great differences among the global rainfall estimates from various sources. TRMM, however, has significantly reduced the ambiguity of the global rain estimate. At the same time, new problems and issues have surfaced. The TRMM PR systematically underestimates the rainfall rate compared with the corresponding rain estimates by other means. To increase the accuracy of rain estimates from TRMM, algorithms more sophisticated than the current ones may be required. Since the lifetime of the TRMM is likely to extend to six years from the originally planned three years, more useful data will be accumulated for data analysis and precipitation studies, and there will be more opportunities to improve algorithms.

NASDA is therefore soliciting research proposals to promote development of advanced algorithms for rainfall estimation and utilization of the TRMM data for understanding the distribution and variation of tropical rainfall. Proposals are sought for new and continuing research associated with TRMM. This opportunity, which follows an earlier TRMM research announcement in 1996, is intended to support subsequent science investigations for the three-year period beginning in April 2001. NASDA will spend approximately 60 million yen during fiscal year 2000 to support scientific activities of the 25 Principal Investigators (PIs) who were selected in the previous research opportunity. However, it should be noted that the budget allocated for the new PIs' activities after fiscal year 2001 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 29, 2000. 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 2001.

All proposers are strongly encouraged to submit a letter of intent (see section 5) to respond to this Announcement by August 18, 2000.

2. TECHNICAL DESCRIPTION

The previous two Research Announcements (RAs) focused mainly on "Algorithm Development" and "Calibration and Validation" for the Precipitation Radar (PR). These efforts have significantly contributed to improving the quantitative accuracy of the rainfall products.

Field campaign experiments, such as the Ishigaki-Miyako Campaign Experiment for TRMM (IMCET), were conducted in the last RA activities. The PR rain estimates were also validated using ground-based radars, rain gauges, etc. The results showed that the TRMM PR rain estimates were qualitatively excellent. For example, horizontal and vertical rain patterns obtained from the PR were very similar to those taken from a ground-based or airborne radar. However, there were some discrepancies between PR-estimated rain volume and other rain data, even though the PR was very well calibrated using internal and external measurements. Generally speaking, PR-estimated rain rates were slightly lower than others. The discrepancy, even though small, significantly impacts the accuracy and sensitivity of the general circulation model forecast. The accuracy of current ground validation results does not reach the required level to validate the PR estimates. Thus, a more sophisticated technique with careful data processing is required. The PR rain estimation algorithm also must be improved. Currently, one of the most important issues is to find a suitable Z-R relationship based on microphysics and observations. The rain attenuation correction technique requires a rain structure model that includes size distributions of both liquid and ice hydrometers.

Algorithm development for estimating physical quantities that cannot be measured directly is a good candidate for the future study. One very important example is global mapping of profiles of latent heat release. This is one of the main goals of TRMM. Using the PR's vertical structure mapping capability together with VIRS and TMI data, TRMM has great potential for achieving this goal.

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 two years of TRMM data have now been accumulated. This RA thus strongly encourages scientific 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.

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, global soil moisture has been mapped using TRMM PR's surface scattering signature. Such research that explores a new application of satellite data is highly encouraged.

Thus, this research announcement seeks proposals in two areas. The first area is "Algorithm Development and Validation" to enhance existing investigations related to algorithm development and validation. The other area is "Modeling and Data Analysis" to promote more application studies.

The proposer should keep in mind that, unlike the last research announcement, NASDA will not support any field campaign or ground observation experiment in this research announcement. 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 explore new utilization of TRMM data. The proposal should describe plans for TRMM data usage well.

Several specific examples of research fields sought by this announcement are given below.

Algorithm Development/Improvement and Validation of TRMM Data

• Combined algorithm development for TRMM sensors to reduce discrepancies among the sensors.
• New algorithm development for TRMM sensors, combined with other satellites and/or ground data set.
• Development of general methods for comparing satellite and ground data and validation of higher order products.
• Development of validation methods using multi-parameter radar data.

Modeling/Data Analysis

• 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.
