Abstract
The TRMM data processing and distribution system is very unique and the first attempt for NASDA and NASA. Now TRMM is operated by NASA and NASA receives TRMM data at NASA/WSC through TDRS. Received raw data are distributed to NASA/GSFC, NASA/LaRC and NASA/MSFC separately depending on the sensors. NASDA/EOC receives PR Level 0, HK, PR Q/L and TMI Q/L data from NASA/SDPF in GSFC, TMI Level 1 product from TSDIS, processed and combined data of TMI and VIRS from GSFC's DAAC, processed data of CERES from LaRC's DAAC, processed data of CERES from LaRC's DAAC and processed data of LIS from MSFC. PR level 0 are processed to Level 1, Level 2 and Level 3 products at both NASDA/EOC and TSDIS. EOC distributes these standard products of PR, TMI, VIRS, CERES, LIS and Combined data according to the data request from users through EUS or FAX. Usually these data one distributed by media such as 8 mm tape, DAT, CD-ROM or MO. New information for researchers is available at EORC home page. The URL is http://www.eorc.nasda.go.jp./TRMM/.
