Table 2. Thresholds used to create the exposure indicator components.

Exposure indicator component	Dimension	Exposure value
Population density (thousand persons/sq.km)	<0.10	0
	≥0.10–<0.25	0.25
	≥0.25–<0.5	0.5
	≥0.5–<1.0	0.75
	≥1.0	1
Land cover component	Urban	1
	Agricultural/plantation	0.50
	Mixed vegetated/agricultural	0.25
	Forest	0
Temperature	Maximum monthly temperature, lag of 2 months	>20°C and ≤34°C : linear increase in exposure up to 1; ≤20°C or >34°C : 0 exposure
Precipitation	Monthly cumulative precipitation, lag of 2 months	<300 mm precipitation: linear increase in exposure up to 1; >300 mm monthly precipitation: 0 exposure
