Cyclone Observed by MODIS Air Mass RGB
Monday, February 8, 2016
An image captured this morning by the MODIS Terra instrument shows an impressive cyclone off the eastern coast of the US. The image on the left shows the cyclone in SPoRT's Air Mass RGB and the image on the right shows the 11.0 μm from Terra (from 8 February 2016 at 1427 UTC). The deep red color on the RGB shows the intrusion of ozone-rich stratospheric air, which is an indication of deformation zones, jet streaks, and potential vorticity anomalies associated with rapid cyclogenesis, which itself indicates strong winds at the surface. This RGB is also limb-corrected for cooling at the edges of the swath, so we can assume the cyclone in this imagery is every bit as intense as it looks. The new generation of geostationary satellites being deployed globally, such as Himawari, MTG, and GOES-R, will allow us to observe imagery like the Air Mass RGB several times an hour, enabling us to watch the cyclogenesis as it happens.
SPoRT Response to Tornado Damage and Recovery in Moore, Oklahoma
On May 20, 2013, the city of Moore, Oklahoma was struck by an EF-5 tornado that devastated a large swath of the community. In response to the event, the SPoRT team developed several products as part of an ongoing feasibility study to examine the utility of NASA, NOAA, and commercial satellite data in responding to disaster events. Immediately following the event, the VIIRS day-night band was used to identify power outages across Moore, Oklahoma and southern portions of Oklahoma City that resulted from the storm. As skies cleared from west to east, cloud-free imagery from the morning of May 21 was compared to the morning of May 20 and difference imagery identified the outage area. SPoRT distributed the VIIRS day-night band imagery through a tiled imagery viewer and shared results with end-user partners and NASA Headquarters management.
