NASA | Scanning a Snow Storm

Показать описание

On March 17, 2014 the Global Precipitation Measurement (GPM) mission's Core Observatory flew over the East coast's last snow storm of the 2013-2014 winter season. This was also one of the first major snow storms observed by GPM shortly after it was launched on February 27, 2014.

The GPM Core Observatory carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure - and how it will behave. The GPM Microwave Imager sees through the tops of clouds to observe how much and where precipitation occurs, and the Dual-frequency Precipitation Radar observes precise details of precipitation in 3-dimensions.

For forecasters, GPM's microwave and radar data are part of the toolbox of satellite data, including other low Earth orbit and geostationary satellites, that they use to monitor tropical cyclones and hurricanes.

It would be great to have more satellites to accomplish more thorough coverage of this big fat planet. We are learning so much.

Very, very, very cool. I've always wanted actual three-dimensional scanning of storms. (I'm not being sarcastic; I'm quite interested in weather)

can any of you share the time of this observation?

This video is strikingly Americo-centric. This storm was hardly the last to hit the East Coast of this continent in the '13-'14 winter season.
