I'm not quite sure what about the 1997 and the present haze you would like to get more information on. Please look up an article about the 1997 haze which I wrote with Prof. Brauer entitled 'Fires in Indonesia : Crisis and Reaction' which was published in Environmental Science & Technology / News, Vol. 32, No. 17, pp. 404A-407A. As for the present hazy condition over the Klang Valley, I don't have any clear idea of how serious it is or it is going to be, as we no longer have the privilege of checking for the API at the DOE website. I've been monitoring the PM10 levels in Cheras for 2 days now, and I should have an idea soon of the atmospheric PM10 concentration. Contact me by e-mail if you are interested.
