Compact Infrared Camera(CIRC)
Compact Infrared Camera (CIRC) is an infrared sensor primarily intended for detecting forest fires, which present a serious problem for the various countries of Southeast Asia, particularly considering the effects of global warming and climate change. Lightweight, compact, and with low power consumption, CIRC can be mounted on multiple satellites to enable high-frequency observation. Installation of CIRCs on the ALOS-2 satellite to be launched in 2013 and on the JEM/CALET to be launced in 2014 is expected to increase observation frequency.
The ultimate goal of the CIRC project is to minimize the damage and impact caused by forest fires, as well as contributing to urban planning and our understanding of volcanic disasters.
