TRMM Measures Rainfall In Ikola And Joalane

TRMM Measures Rainfall In Ikola And Joalane

Since being launched in November 1997 the TRMM satellite produced huge volumes of precise precipitation measurements for use in climatology . Near real time collection of data also provided valuable information such as rainfall distribution, three dimensional structure and the stages of development for tropical cyclones.

The TRMM satellite saw two tropical cyclones with successive orbits over the the South Indian Ocean on Tuesday April 7, 2015. Cyclone Ikola was the first to come into view when TRMM passed over at 1646 UTC and then the satellite had a good look at cyclone Joalane at 1755 UTC. Data collected by TRMM's Microwave Imager (TMI) instrument were used to show the distribution of rainfall near Ikola and Joalane. TMI revealed the exact location of intense rainfall near Ikola's center and within Joalane's distinct eye wall. TRMM TMI rainfall measurements are shown overlaid and aligned with enhanced infrared images using data received by the METEOSAT-7 satellite at almost the same times as the TRMM orbits.
