TRMM Satellite Passes Over KWAJEX

For each overpass time an image of the reflectivity observed by the Kwajalein S-band radar is shown in the left panel. It is a horizontal map at the 3-km level derived from the three-dimensional volume scan for the indicated time. Range marks are at 20-km intervals. The geography of the Kwajalein Atoll is shown in yellow. The atoll only occupies the yellow lines. The area covered by the radar is almost all open ocean. The NOAA ship Ronald H. Brown is located 40 km south of the Kwajalein radar during the first IOP and 40 km southwest of the Kwajalein radar during the second IOP. The overlapping yellow circles show that dual-Doppler radar lobes for the combined Kwajalein and ship radars. The middle panel contains the TRMM Microwave Imager (TMI) 85 GHz image. The right panel contains the TRMM satellite Precipitation Radar (PR) image. Range rings on the TMI and PR images indicate the 150 km radius from the Kwajalein S-band and Ronald H. Brown C-band during the first IOP.
