A new data product developed by scientists at the National Oceanic and Atmospheric Administration (NOAA), the National Environmental Satellite, Data, and Information Service (NESDIS), and NASA’s Short-term Prediction Research and Transition (SPoRT) Center will be able to provide a more quick and effective calculation of snowfall rates by satellite.

NASA releases first global rainfall and snowfall map

NASA’s Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall.

The GPM Core Observatory – launched one year ago on 27 February 2014, as a collaboration between NASA and the Japan Aerospace Exploration Agency – acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map.

Satellite images show the Great Lakes in Canada covered with ice

NASA's satellite Aqua captured this MODIS natural color image of lake Erie
MODIS infrared image of Lake Erie in Canada showing the ice cover

The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired these images on January 9, 2014. The extreme cold weather that paralyzed North America early this year brought thick ice over the Great Lakes in Canada.

The top image shows Lake Erie in natural color, the second one shows a blend of shortwave infrared, near infrared and red that help distinguish ice from water. Ice is pale blue, the thicker the brighter, open water is navy, and snow is green.

NASA maps global temperature anomalies in US and Europe

MODIS image caught by NASA's Terra satellite shows the polar vortex over America
MODIS image caught by NASA's Terra satellite shows high temperatures in Europe

NASA satellite data shows the recent weather divergences on Earth - particularly in North America and Europe. At the beginning of 2014 the temperatures in the northern hemisphere showed how the atmosphere can produce two contrasting weather extremes at the same time. While in northern America the temperatures fell way below zero, most of Europe enjoyed temperatures of +10 degrees Celsius.
