It is very important to realize that these Montserrat eruptions are all very small in scale, even the largest Montserrat eruptions, such as 26 December 1997, are an order of magnitude smaller than the 1992 Spurr eruptions. In the studies cited above, the larger Montserrat events were studied in the most detail. The 18 September event studied by Simpson et al, 2000 was another order of magnitude smaller in scale than the larger Montserrat events and its silicate signal in the split window is too weak (less than about 10,000 tonnes of fine ash (1-25 mm in diameter) to overcome the effects of water vapor (Rose and Mayberry, 2000). Besides the problem of high atmospheric water vapor, the Montserrat eruptions include volcanogenic meteorological clouds, derived from the interaction of volcanic material with the ocean surface (Mayberry, 1999; Mayberry et al 2001), and these features must also be realized by an interpreter. The reader is referred to the studies above for much more detail on Montserrat volcanic clouds which have been very informative for improvement of the split window algorithm for volcanic clouds. Thus the Montserrat example developed by Simpson et al 2000 is poorly selected as representative of a tropical event.A8 symbolT T2'Possible Addition to the Spurr section:T T;0The Spurr example shown by Simpson et al has also been highlighted in several papers already and throughly explained (Schneider et al, 1995; Andres and Rose, 1995). The high optical depth of the young volcanic cloud can be easily interpreted from the low brightness temperatures and this allows valuable information to be inferred in real time, eg that this volcanic cloud is still in its early development. Thus rather than a failure, this example is already widely known to depict some of the value of two band IR data for interpreting hazards to aircraft.T iTAndres, R. J. and W. I.
