On 25 March, Åland Post issues a stamp featuring the Suomi NPP weather satellite, named after Åland descendant Verner E. Suomi. Also known as ”the father of satellite meteoro- logy”, Suomi contributed to laying the foundations for today’s weather satellites, essential for providing weather forecasts. Åland illustrator Peter Bergström has designed the stamp.
Verner E. Suomi (1915–1995) was among the earliest to understand the im- portance of satellites for weather observations. His parents Johan Suomi, born in Kustavi in the archipelago of Åboland, and Anna Matilda Sundqvist from Pett- böle, Finström, emigrated from Åland to the USA in 1902. Verner grew up in Eveleth, Minnesota, as the second youngest of seven siblings.
Launched in 1959, the Explorer VII Satellite carried Suomi’s rst instrument, a at plate radiometer that measured the Earth’s heat balance from space for the rst time. It was discovered that clouds play an important role in the Earth’s energy budget and that the Earth absorbs more radiated solar energy than was previously recognized. Suomi’s most important invention is probably a camera that was added to the ATS-1 Satellite launched in 1966. Its geosynchronous orbit enabled scientists to observe the formation of weather systems without interruptions. Until then, all we had seen were interesting snapshots from space but, with Suomi’s ”Spin-Scan Cloud Camera”, scientists could monitor air mo- tion, cloud height and rainfall among other phenomena.
Since 2011, the American weather satellite Suomi NPP on the stamp monitors the Earth’s cloud cover, oceans, ice sheets, vegetation, and the heat radiation from the Earth’s atmosphere. The Suomi NPP is a polar orbiting satellite and is one of several satellites providing data for weather forecasts in Finland.
