| 摘 要： | To study the possibility of improving the precision of retrieving precipitation through GMS-5infrared data,the relationship between the data of GMS-5 infrared channel 1(IR1)andprecipitation sounded by TRMM/PR was carefully studied through some cases gathered during theHUBEX 1998.First of all,the relationship between the brightness temperature(Tb)and PR-sounded near-surface rainfall rate(NSRR)was studied.Then,as PR can sound the innerstructure of rainfall area.a unique advantage of this new instrument,the relationship between Tband PR-sounded rainfall rate in each layer was also studied.Still,as PR can tell the rain type,those relationships were studied again according to the different types of precipitation(i.e.convective and stratiform).After comparing these outcomes with those from other references,itcan be concluded that the relationship between Tb and PR-sounded rainfall rate is acceptable and itis possible to calibrate precipitation retrieved through Tb by PR data. |
