on Saturday successfully launched for the National Oceanic and Atmospheric Administration (NOAA) a highly advanced polar-orbiting satellite to improve up to seven days in advance.

The (JPSS-1) lifted off on a United Launch Alliance Delta II rocket from Vandenberg Air Force Base, California, said.

"Launching underscores NOAA's commitment to putting the best possible satellites into orbit, giving our forecasters -- and the public -- greater confidence in up to seven days in advance, including the potential for severe, or impactful weather," said Stephen Volz, Director of NOAA's Satellite and Information Service.

This is the first in a series of four such satellites in a collaborative programme between and

will be renamed NOAA-20 when it reaches its final orbit.

Following a three-month checkout and validation of its five advanced instruments, the satellite will become operational, said.

The satellite will improve weather forecastings, such as predicting a hurricane's track and will help agencies involved with post-storm recovery by visualizing storm damage and the geographic extent of power outages.

data will also improve recognition of climate patterns that influence the weather, such as El Nino and La Nina, according to
