With regard to cross-border environmental pollution, for instance, or smell coming from Johor, we work very closely with our Johor counterparts, that is, DOE Johor and also the Johor BOMBA. We also have continuous monitoring as well as our remote satellite sensing to identify smoke plumes as well as hotspots. But these, obviously, would be for the larger hotspots and smoke plumes that we can detect and, depending on the wind direction, whether they will actually travel down to Singapore. So, for the recent early February to mid-March incidents, because of the northeasterly winds, fires normally occurred in the afternoon. That is how we have spotted it. By the time it comes in in the evening when the wind has weakened or slowed down, as well as the temperatures have cooled, these smells, if there are, would be harder to dilute and disperse because it will be hard to disperse the air pollutants upwards due to the cooler temperature and then the wind does not take it away. So, by daytime, in the morning, the sun is up and the wind speed has gathered strength, it then gets diluted and dispersed away.
