The Meteosat-7 visible imagery (Figure 1, right frame), 23 October 03:00 UTC, shows extensive haze over large parts of Asia. Comparing it to the infrared image at the same time you can distinguish the haze from the cloud.
Stations in the area were reporting haze or smoke haze with visibility around 2000–4000 metres, but some stations were reporting visibility as low as 800 metres in smoke haze.
An inversion was trapping the haze at relatively low levels. However, on the island of Java several darker circles can be seen along the spine of the island where the mountain tops are higher than the inversion, so the mountain tops are visible through the clean air above the inversion.
