The types of sensors that the U.S. Geological Survey and NASA sends up on Earth-orbiting satellites to capture imagery through its Landsat program typically record light from a broader segment of the spectrum—visible light wavelengths, near infrared (750-950 nm), two shortwaveinfrared wavelengths...
How do satellites help meteorologists forecast the weather? How does wind shear affect thunderstorms? How does a waterspout form? How do weather maps work? Why are waterspouts weaker than tornadoes? Why are tornadoes measured using the Fujita scale?
Satellites are now used as well, but they suffer from many of the same problems. Scientists do the best they can, using extremely long time spans, to try to figure out what the sea level is and whether or not it is rising. The general consensus seems to be that the oceans rise about...
Current predictions suggest that the climate will continue to change for decades into the future, regardless of the mitigation actions we take. Caribou and reindeer have tremendous socioeconomic value in the north, and if we want to maintain sustainable caribou harvesting and husbandry in the future...
Compared with 2.4 GHz frequency band, 5 GHz frequency band has fewer interference sources and more devices begin to use the 5 GHz frequency band, such as cordless phones, radars, wireless sensors, and digital satellites. In most cases, microwave ovens work at the frequenc...
— 10 devastating signs of climate change satellites can see from space— Climate change is making Earth dimmer Older sediments, however, reveal a much shorter cycle, of about 40,000 years, which would reflect the changes in Earth's obliquity, the tilt of its axis. What caused this sudden...
