Each NOAA and NASA have a fleet of Earth-gazing satellites always retaining a watch on the planet for climate forecasts, catastrophe response and long-term local weather monitoring.
The knowledge gained from the fleet might be helpful in producing native forecasts. For instance, after atmospheric rivers are noticed, NOAA can provide flood warnings to probably affected areas so far as per week upfront, the company stated.
