  TANSO-CAI loaded on the Greenhouse gases Observing SATellite (GOSAT) "IBUKI" captures the plume of ash cloud from the Sangeang Api volcano in Indonesia on May 31.

  The Sangeang Api volcano in Indonesia, which elevation is 1949m and geolocation is S8.2 deg. in latitude and E119.07 deg. in longitude, made a huge eruption on May 30.
The Greenhouse gases Observing SATellite (GOSAT) "IBUKI" observes the greenhouse gases with TANSO-FTS and clouds and aerosols with TANSO-CAI globally for every 3 days. The plume of ash cloud emitted by its major eruption was captured by TANSO-CAI observed on May 31.

TANSO-CAI is an imager to observe clouds and aerosols with 4 bands, whose central wave length are 1600 nm, 870 nm, 674 nm and 380 nm respectively. The color composite images of this article are created with its 870 nm data for red channel, 674 nm for green and 380nm for blue. The smoke is shown in yellow, clouds in white and land vegetation in red on this image.
