Datameteo NOW: Actual Weather, satellite, reanalysis data
Nowadays weather is one of the most important word in our daily life. Internet is full of weather sources and for many people the search of the most reliable forecast this is becoming a true obsession.
Yesterday and actual weather can be known not only in places where a meteorological station is installated.
Nevertheless, measurements remain available only for less than 1% of the Earth's surface, we collect weather data for more than 17000 weather stations ingested worldwide Quality data check performed by a Validation tool built in house generating missing data gaps too
The validation tool apply the most recent WMO specifications ( validity data checks , spatial consistency checks etc..) and data coming from WMO reports ( SYNOP, METAR) are available in a readable format.
Reanalysis can integrate the other actual data sources ( ground stations, buoys, radiosoundings , satellite feeds ) in order to provide the most accurate weather climate scenary that become a sort of memory of the climate change. In this way we can have the most accurate weather information than can be used to calculate a forecast.
Weather satellites are used to get a space-bird's eye view of Earth's atmosphere. Visible and infrared images are used to detect the amount of water vapour at various altitude or and ground and sea temperatures while winds can be calculated by measuring cloud motion and precipitation amount estimated.
Using a combination of the visible and infrared channels , skin temperature, radiation can be detected and validated as a new frontier of the sat monitoring.
