abstract = "The accurate measurement of precipitation is important to
understand some meteorological systems. Weather systems are
complex and evolve rapidly and to measure rain, snow and other
types of precipitation on the ground is challenging. However,
satellite sensors can provide observations from which
precipitation estimates can be generated. In this work, the level
2 instantaneous swath based precipitation products generated by
the Goddard Profiling algorithm GPROF2014 scheme are evaluated
using standard descriptive and statistical scores against
SOS-CHUVA surface radar dataset, over the southeast of Brazil. It
was used the passive microwave sensors such as Special Sensor
Microwave Imager/Sounder (SSMIS), Microwave Humidity Sounder
(MHS), Advanced Technology Microwave Sounder (ATMS), Global
Microwave Imager (GMI), Advanced Scanning Microwave Radiometer
(AMSR2) which are products of satellites F16, F17, F18, NOAA18,
METOPA, METOPB, NPP, GPM, GCOMW, respectively. Preliminary results
show that the current GPROF retrieval technique tends to
overestimate the occurrence of light precipitation, leading to an
overestimation of the volumetric contribution by light
precipitation intensities, while it underestimates moderate to
heavy precipitation.",
