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

Topic: Ghost Hunting Equipment Specific Purpose: To inform the interviewing jury the proper equipment used for a successful ghost hunt. Introduction: I. Attention Material: Ghost hunting is filled with different types of emotions. Scary‚ sad‚ excited‚ nervous‚ angry‚ etc. are all different emotions you could feel during a ghost hunt. All in all though it is a fun time and cool to experience with your friends. It is also very interesting to hear the history of a specific area and have

heating by solar radiation were the only warming mechanism. Solar radiation at the high frequencies of visible light passes through the atmosphere to warm the planetary surface‚ which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases‚ which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse but

CIRCUIT IDEAS REMOTE-CONTROLLED FAN REGULATOR Dr C.H. VITHALANI sing this circuit‚ you can change the speed of the fan from your couch or bed. Infrared receiver module TSOP1738 is used to receive the infrared signal transmitted by remote control. The circuit is powered by regulated 9V. The AC mains is stepped down by transformer X1 to deliver a secondary output of 12V-0-12V. The transformer output is rectified by full-wave rectifier comprising diodes D1 and D2‚ filtered by capacitor C9 and regulated

What is Remote Sensing? Remote sensing‚ in simplest words‚ means acquiring information about an object without touching the object itself. Conventionally‚ however remote sensing has come to imply that the sensor and the target are located remotely apart and the electromagnetic radiation serves as a link between the sensor and the object‚ the sun being the major source of energy illuminating the earth. The part of this energy is reflected‚ absorbed and transmitted by the surface. A sensor records

increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the sun ’s warmth in a planet ’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet ’s surface. In simpler terms‚ this means that the pollution emitted from the earth‚ such as the gasses from factories‚ cars etc. enter the atmosphere and the co2 from these gases absorb the heat from the sun and
