1. Anticyclone Transport

Strat Ozone 150 hPa

• …

Anthro 150 hPa

Lightning NO

2. Pollution over Northern Bay of Bengal, Nepal

Anthro emissions

• Weak transport of pollution from India over BoB

• Pollution over Nepal mainly from India

3. Outflow from cumulus, cloud processing

Anthro, 25-day soluble tracer

• Low values of soluble tracer indicate extensive cloud processing of air at 200 hPa

• Significant biogenic tracers aloft over Borneo to west of Sumatra

Lightning NO
