More robust observational data gives weather forecasters better information to develop a forecast. But data from so many different sources – 64,000 – is not easily integrated. That’s where scientists at NOAA’s Earth System Research Laboratory came in to develop the system called the Meteorological Assimilation Data Ingest System (MADIS) to make this wealth of data more accessible and usable. This research project successfully transitioned into operations by NOAA’s National Weather Service in late January. It is another example of NOAA’s work to strengthen the effectiveness of the National Weather Service to provide environmental intelligence to communities and businesses, enabling them to become ready, responsive and resilient in the face of extreme weather, water and climate events.
