Infrared Imagery How does infrared imagery show land surface temperatures? in this informative video, we will uncover the fascinating technology behind infrared imagery and h. Therefore, infrared imagery is the display of either cloud top temperatures or earth's surface temperature (if no clouds are present). when skies are clear, the satellite senses radiation emitted by the surface of the earth, but when clouds are present, the satellite senses radiation emitted by the tops of the highest level clouds.

What is an infrared satellite image? infrared satellite images play a vital role in understanding weather patterns and temperature variations across the glob. The resolution of ir imagery from geosynchronous satellite is on the order of 8 kilometers. surface features can be detected in ir imagery by noting subtle shading contrasts resulting from differences in the surface temperatures. one example is the relative temperature difference between large water bodies and land. warm land surfaces tend to. Infrared and visible imagery are essential tools in meteorology for identifying cloud types, determining thunderstorm intensity, identifying fog, and monitoring cloud thickness.
Figure 12 From Reconstruction Of Hourly All Weather Land Surface The resolution of ir imagery from geosynchronous satellite is on the order of 8 kilometers. surface features can be detected in ir imagery by noting subtle shading contrasts resulting from differences in the surface temperatures. one example is the relative temperature difference between large water bodies and land. warm land surfaces tend to. Infrared and visible imagery are essential tools in meteorology for identifying cloud types, determining thunderstorm intensity, identifying fog, and monitoring cloud thickness. These regions of low intensity ir emission are shown as white and light gray in the ir photo. thus, high clouds are white. low clouds, with temperatures near that of the surface, are often medium gray. the surface and the oceans in the lower latitudes appear dark gray. on a sunny afternoon, the land heats up sufficiently to appear almost black. An ir instrument provides information on the temperature of land, water, and clouds by measuring the infrared radiation emitted from surfaces below the satellite. the radiant energy measured by infrared radiometers is converted to a temperature. ir imagery can be used to distinguish low clouds from high clouds. By analyzing infrared data, meteorologists can differentiate between different types of clouds, assess moisture levels, and study land and sea surface temperatures. the ability to measure emitted heat enhances weather predictions and furthers climate understanding. As outlined in section 2 and illustrated in fig. 1, our goal is to use multispectral measurements in the infrared bands to determine two different surface temperatures, specifically snow (t ss) and forest (t forest), in a grid cell containing both. we use aerial measurements to demonstrate the feasibility of the concept, and then compare.
