Observation of concentrated heavy rain in Pakistan by AVNIR-2 onboard "Daichi" (ALOS) (7)

Northwestern Pakistan in the central Asia has been seriously damaged due to floods and mudslides caused by heavy rain which had occurred continuously since July 29, 2010.
The Japan Aerospace Exploration Agency (JAXA) has performed the observation to monitor the state of the damage by the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2)* onboard the Advanced Land Observing Satellite (ALOS, "Daichi") at 15:07 (JST) or 6:07 (UTC) on September 6, 2010 further to August 3, 5, 6, 15, 23 and September 1, 2010.

Fig. 1 shows an observed image and is assigned band 3, 2 and 1 of AVNIR-2 as the true color composite.

Figs. 2 and 3 show enlarged images of swollen rivers which were taken after disaster on September 6, 2010 (left) and before disaster on December 4, 2009 (right). Figs. 2 and 3 are located in Kashmore and Dera Ismail Jhan, respectively. They are assigned band 4, 3 and 2 of AVNIR-2 as the false color composite, therefore vegetation can be seen in red color and flood areas can be done clear in light blue color. In comparison to before as well as after disaster, they indicate that flooded area still remains unchanged.

JAXA plans continuous observation of this region.

* Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2):
AVNIR-2 is a visible and near infrared radiometer for observing land and coastal zones.
It provides 10-m spatial-resolution image and 70-km swath on the ground. The pointing angle of AVNIR-2 is +44 and - 44 degrees. This image was acquired by 0.0 degree. The images taken after disaster on September 6, 2010 and before disaster on December 4, 2009 were acquired by 0.0 degree, respectively.
