PPT Slide

Locate all geostationary data within

the past 30 minutes

SSM/I polar orbit ingest

(F-11, F-13, F-14)

Geostationary data ingests

(GOES, GMS, Meteosat)

Spatially average geostationary channels to the SSM/I rain rate resolution

Compute SSM/I rain field and

co-locate each zero or greater rain

rate with its IR brightness temps

Save all zero or greater rain rate pixels into a file along with pixel geolocation, insert date-time info for chronological searching

Update global histogram-matched

TB-rain rate relations:

• Global 15-degree boxes at

5-degree lat/lon intervals

• Use previous N=24 hours of

collected IR-rain rate statistics

Read latest geo-SSM/I histogram file

Compute rain rate from this geostationary data using nearest TB-rain rate relation pixel-by-pixel

Apply tests to screen non-raining high clouds
