New NOAA Polar-Orbiting Satellite will help Improve Alaskan Weather and Hazard Forecasts

    Juneau, Alaska (KINY) - A new technology will allow forecasters to see more weather impacts at night, which is important given the length of darkness in Alaska during winter.

    Experts from NOAA will discuss the new JPSS-1, the first in a series of four advanced NOAA polar-orbiting satellites called the Joint Polar Satellite System. It will be used by scientists to help improve weather and natural hazard forecasts in Alaska. The discussion is scheduled for Tuesday.

    The instruments aboard the new satellite will provide more than 40 data products, many of them critical for Alaska. They include atmosphere temperature and moisture profiles, precipitation type and rate, clouds and fog, winds, sea surface temperature and ocean color, sea ice extent, snow cover and depth, vegetation greenness indices and health, and volcanic ash and fire detection. The JPSS-1 satellite also has a visible spectrum light at night, which allows forecasters to view clouds, fog, smoke, and even lights at night.

    The satellite data will also increase the timeliness and accuracy of forecasts for three to seven days in advance of severe weather events. This will enable emergency managers to make timely decisions to protect lives and property and order effective evacuations when necessary.
