| Popis: | On satellite images in the near-infrared 3.7 μm atmospheric window some low clouds appear warmer than the sea. A simple analysis of the radiation balance of elements of the cloud and sea surface indicates that the anomaly can be explained by the difference in reflectance between these elements. In some areas of the image, low clouds return more reflected solar radiation to the satellite than does the background sea. These clouds may then appear warmer. A method to measure the albedo of clouds using these satellite data is suggested. |
