An additional problem for this source is that available data are often limited to one or a few years and<br />

that the also the extent of burning often substantially differs between years (Fig. A.2.15). Using the<br />

counts of satellite observations of so-called hot-spots to identify the seasonal patterns of biomass burning<br />

(e.g. Fig. A.2.16), is also not straightforward. In Fig. A.2.17 the results of two algorithms for identifying<br />

hotspots for biomass burning are compared. Although the two patterns look similar the deviations from<br />

the uniform distribution are rather different.<br />
