MODIS Data WebThe atmosphere of Venus is about 96 percent carbon dioxide, with surface temperatures of about 737 K (464 °C, or 867 °F). Clouds on Venus are made of sulfuric acid (H 2 SO 4) and move in an easterly circulation of about 100 metres per second (224 miles per hour). Venus itself rotates only once every 243 Earth days.
WebThe AATS is a 14-channel instrument that measures a sun beam’s transmission through the atmosphere at different wavelengths (colors of light). The MODIS is a 36-channel optical scanner that measures both visible and near-infrared wavelengths. It has spatial resolution, ranging from 250 meters to 1 kilometer. “Technically, AOD is a ...
