VIIRS Sees a Blanket of Snow over New England
Snow blankets northeastern New York State and most of New England in this true-color image captured by the Visible Infrared Imager Radiometer Suite (VIIRS) instrument aboard NOAA/NASA Suomi NPP on March 22, 2017. To create true-color images like this one, scientists combine data from three of VIIRS's 22 channels--namely those sensitive to green, red, and blue wavelengths of light--along with supplemental data from other channels. VIIRS provides coverage of the entire globe twice a day with 750-meter resolution across its entire scan. In doing so, it offers better coverage than its instrument predecessors, which has led to improved atmospheric and environmental satellite data products, pertaining to vegetation health, phytoplankton abundance, clouds, smoke plumes and dust, and as shown here, ice and snow cover.
