The measurement is important because clouds play a large role in regulating the amount of energy that reaches the Earth from the sun as well as the amount of energy that the Earth reflects and emits back into space. These maps show monthly cloud fraction from January 2005 to the present, produced using data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard NASA’s Terra satellite. Like a digital camera, MODIS collects information in gridded boxes or pixels. Each box covers one square kilometer. Cloud fraction is the portion of each pixel that is covered by clouds. Scientists make this measurement by counting the number of pixels in a 25-square-kilometer box (5 pixels tall by 5 pixels wide) that are cloudy and dividing that number by 25. Scientists use these measurements to better understand how much of the Earth is covered by clouds and how changes in Earth’s climate may alter the amount and types of clouds that form. || ", "hits": 83 }, { "id": 30397, "url": "https://svs.gsfc.nasa.gov/30397/", "result_type": "Hyperwall Visual", "release_date": "2013-10-24T12:00:00-04:00", "title": "Monthly Cloud Fraction (Aqua/MODIS)", "description": "Cloud fraction is the measurement scientists use to determine how much of the Earth is covered by clouds.

The simulation was seeded at the beginning of the run and then ran on its own to create a 2 year simulation. Only 25 days of the full run are depicted here. The ocean color layer ranging from blue to orange depict air temperatures 2 meters (T2M) above sea level. Since Sea Surface Temperatures (SST) are typically measured at sea level and below, the T2M model output behaves somewhat differently. Nonetheless, it is a reasonable proxy to SST. Landcover information is taken from the Next Generation Blue Marble dataset. Sea Ice is depicted as solid white and clouds are shades of white. The wind layer is depicted as flowing white arrows.This project was developed in support of a hyperwall show titled \"Pursuit of Light\" which is scheduled to premiere on April 19, 2012 at the Smithsonian Uvar-Hazy Center during the space shuttle Discovery Transfer Ceremony on a Jumbotron. The hyperwall itself is a multi-screen display system that allows for the display of very high resolution images beyond current 1080p HDTV standards, allowing for much greater detail to be shown on much larger screens.
