2 NASA, CGMS-43, May 2015 Coordination Group for Meteorological Satellites - CGMS MISR Wind Observations of Kármán Vortices  MISR research algorithm to produce 4.4 km winds, capturing the fine structure of Madeira island wake flows  Vortex streets as a 3D pattern in 2D inviscid flow over a obstacle  Good agreement found between the observed and WRF-simulated winds at instantaneous cloud-levels Courtesy of Akos Horvath and Kevin Mueller

3 NASA, CGMS-43, May 2015 Coordination Group for Meteorological Satellites - CGMS RapidScat Launched to ISS on 20 September 2014  (A) ISS RapidScat showing emission of the two pencil- beam scatterometer  (B) RapidScat wind speed and direction measurements near Philippines on 6 December 2014 when Typhoon Hagupit (also known as Typhoon Ruby in the Philippines) made landfall. Maximum wind speed recorded by RapidScat was about 95 miles h-1  (C) Aerial view of Typhoon Hagupit recorded by astronaut Terry Virts on the ISS on 6 December 2014. http://www.bbc.com/news/world-asia-30366091
