Days of heavy rains have lead to devastating landslides on the Indonesian island
of Sulawesi (formerly Celebes). So far the death toll has exceeded 200 with
many more still missing. The hardest hit area was Sinjai in South Sulawesi.
The primary mission of the Tropical Rainfall Measuring Mission satellite,
also known as TRMM, is to measure rainfall over the global Tropics. It was
placed into service in November of 1997. From its low-earth orbit, TRMM has
been measuring rainfall over the global Tropics using a combination of passive
microwave and active radar sensors. It can be used to calibrate rainfall
estimates from other satellites. The TRMM-based, near-real time Multi-
satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center
monitors rainfall over the global Tropics. MPA rainfall totals are shown here
for the period 14 to 21 June 2006 for the island of Sulawesi in central
Indonesia and the surrounding area. The highest rainfall totals for the period
(shown in red) are on the order of 10 to 12 inches. The southernmost area of
heavy rain is near the southern tip of Sulawesi and covers the higher terrain
adjacent to Sinjai. Deforestation in the region is believed to be a contributing
factor in the disastrous mudslides.
TRMM is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). Images produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC).
