The “National Polar-orbiting Operational Environmental Satellite System Preparatory Project” or NPP represents the first mission conceived with the sole purpose of study the weather events on a short term. This would allow understanding the climate changes on a long term.
The NPP was made under a budget of 1,500 million dollars; this machinery is equipped with five scientific instruments to analyze the ozone layer, measure the atmosphere temperature and the movement of the polar plates.
James Gleason, the scientist responsible of creating the satellite in the Goddard center explained that the observations of the NPP would show the changes that planet is experiencing. The forecasters U.S. National Oceanic and Atmospheric (NOAA) will add the data registered by the NPP into their models in order to produce weather forecasts. (AV)
