Abstract:
We present the new Precipitation REtrieval covering the TIbetan Plateau (PRETIP) as a<br/>
feasibility study using the two geostationary (GEO) satellites Elektro-L2 and Insat-3D with reference<br/>
to the GPM(Global PrecipitationMeasurementMission) IMERG (IntegratedMulti-satellitE Retrievals<br/>
for GPM) product. The present study deals with the assignment of the rainfall rate. For precipitation<br/>
rate assignment, the best-quality precipitation estimates from the gauge calibrated microwave (MW)<br/>
within the IMERG product were combined with the GEO data by Random Forest (RF) regression.<br/>
PRETIP was validated with independent MWprecipitation information not considered for model<br/>
training and revealed a good performance on 30 min and 11 km spatio-temporal resolution with a<br/>
correlation coefficient of R = 0.59 and outperforms the validation of the independentMWprecipitation<br/>
with IMERG’s IR only product (R = 0.18). A comparison of PRETIP precipitation rates in 4 km<br/>
resolution with daily rain gauge measurements from the Chinese Ministry of Water Resources<br/>
revealed a correlation of R = 0.49. No differences in the performance of PRETIP for various elevation<br/>
ranges or between the rainy (July, August) and the dry (May, September) season could be found.
