Weather satellite of rotation and its elliptical orbit kept it from collecting a notable amount of useful data. The Explorer VI and VII satellites also contained weather-related experiments. The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. TIROS operated for 78 days and proved to be much more successful than Vanguard 2. TIROS paved the way for the Nimbus program, whose technology and findings are the heritage of most of the Earth-observing satellites NASA and NOAA have launched since then. Beginning with the Nimbus 3 satellite in 1969, temperature information through the tropospheric
The Weather Network introduced new local weather products including an hourly forecast for the next 12 hours in 2006, long term precipitation forecasts in 2008 and improved satellite and radar maps in 2009. In 2009, The Weather Network was granted 9(1)("h") must-carry status by the CRTC, under the condition that Pelmorex develop a "national aggregator and distributor" of localized emergency alert messages. In early 2013, The Weather Network launched regional feeds, currently for Alberta and the Maritime provinces. Each feed features its own regional forecasts, weather stories, and where available, traffic information was provided by Beat the Traffic. On December 8, 2014, The
