STAR Scientist Presents Top Poster at 2010 MicroRad Conference
 MIRS N18_METOPA_F16
Precipitation Estimate 12-12Z (mm/day) 10-10-2009March 6, 2010 - STAR congratulates Flavio
Iturbide-Sanchez, a STAR contractor on the MiRS project, who recently won
first prize in the MicroRad 2010 poster contest. MicroRad is a prestigious conference
dedicated to microwave remote sensing science and takes place every
two years. This year, the MicroRad Conference took place in
Washington, DC. Flavio was honored for his poster about the MiRS
rainfall rate measurement entitled "Development
and Validation of a Rainfall Rate Algorithm Based on Hydrometeor
Products Derived from Passive Microwave Satellite Observations".
This work presents the development of a satellite-based rainfall
rate algorithm that uses hydrometeors (cloud liquid water, rain water
and ice water) derived by the one-dimensional variational (1D-VAR) and
physical-based Microwave Integrated Retrieval System (MIRS) to
retrieve surface precipitation amounts in mm/hr. The algorithm has
been designed to facilitate its implementation on current and future
satellite-based sensors and to facilitate its transition from research
to operations in a relatively short period of time. The proposed
algorithm has been successfully applied operationally to several
satellite-based sensors, including NOAA-18, NOAA-19, Metop-A AMSU and
MHS, and DMSP-F16 SSMI/S (and is being extended to DMSP-F18 SSMI/S).
For its evaluation, the algorithm has been extensively assessed over
ocean and land surfaces, showing comparable capabilities and quality
to state-of-the-art precipitation products derived from rain gauge,
ground-based radar and satellite-based observations.
