USE OF SATELLITE TECHNOLOGY FOR WEATHER FORECASTING
Weather forecasting is the application of science and technology to predict the state of the atmosphere for a given location and over the years many techniques have been used to forecast the weather, Satellite technology is one of it. The history of weather forecasting and early satellite programmes was told using archive film, highlighting the difficulties associated with a lack of weather data. Two hundred dedicated weather satellites have been launched since the 1960s. Together, these satellites enable us to monitor every weather system around the world and to see the weather as it approaches. Weather prediction can save lives, especially in tropical regions as information from satellites is used to track hurricanes as they develop. The first satellite completely dedicated to weather forecasting was developed by NASA. The satellite was named TIROS-I (television and infrared observation satellite) and was launched on 1st April, 1960. The weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting, covering the entire Earth asynchronously, or geostationary, hovering over the same spot on the equator. Meteorological satellites see more than clouds and cloud systems. City lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows, etc., and other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring the volcanic ash cloud from Mount St. Helens and activity from other volcanoes such as Mount Etna. Smoke from fires in the western United States such as Colorado and Utah have also been monitored. Other environmental satellites can detect changes in the Earth's vegetation, sea state, ocean color, and ice fields. Weather satellites carry instruments called radiometers (not...
