The scene is reminiscent of a modern abstract painting. Colorful circles mingle with straight-edged fields in combinations of red, green, and blue. But each color carries physical meaning, providing clues about crop types and revealing how they changed over the course of the Southern Hemisphere\u2019s growing season.<\/p>\n<p>Data for the visualization were acquired by the <a href=\"https:\/\/science.nasa.gov\/mission\/nisar\/\" rel=\"noopener\">NISAR<\/a>\u00a0(NASA-ISRO Synthetic Aperture Radar) satellite during 10 passes over the area between November 2025 and March 2026. <a href=\"https:\/\/www.earthdata.nasa.gov\/data\/instruments\/l-sar\" rel=\"noopener\">L-band<\/a> radar observations, which can \u201csee\u201d vegetation\u2019s structure instead of its color, were analyzed to produce per-pixel statistical measures across the scene. By combining radar scattering behaviors observed across multiple dates into a single composite, scientists built a compact summary of seasonal agricultural activity and change.<\/p>\n<p>\u201cIt\u2019s a pretty picture, but there are also important things that it communicates to us,\u201d said Paul Siqueira, a scientist at the University of Massachusetts Amherst, and ecosystems lead of the <a href=\"https:\/\/science.nasa.gov\/mission\/nisar\/team\/\" rel=\"noopener\">NISAR science team<\/a>. \u201cWith NISAR, crops like maize and sunflower appear differently than forests because of their size differences and period of growth.\u201d<\/p>\n<p>In this false-color composite, green indicates a vegetated area; red represents an unvegetated surface; and blue indicates how rapidly a vegetated area changed over the season. For instance, stable vegetation\u2014such as forested areas\u2014display a light blue component. Plants that change structure throughout the season, such as wheat and maize (corn), have a darker blue component.<\/p>\n<p>In practice, most pixels contain a mix of these colors, producing the visualization\u2019s rich and varied palette. For example, plants that grow rapidly (contributing some green) and are harvested early (contributing a large red component) make fields appear orange. Sunflowers are known to exhibit this pattern in the region, though ground validation would be needed to confirm their presence in any given field. <\/p>\n<p>The processing behind the visualization is relatively straightforward, but it is based on a large amount of data. NISAR sends radar signals to Earth and measures how they bounce back; the orientation of the returned radar waves (cross-polarized or co-polarized) carries information about the structure of vegetation and surfaces. By combining radar measurements from multiple satellite passes and calculating statistics for each pixel, scientists built the detailed map of the landscape\u2019s characteristics throughout the growing season.<\/p>\n<p>The technique provides a repeatable way to monitor crop development, the impacts of irrigation, and land-use change across large regions. As NISAR collects more data, researchers will be able to compare seasons, track field-to-field differences in growth patterns, and better understand how agricultural systems respond to water availability and climate variability.<\/p>\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p><em>Image by Paul Siqueira (UMass Amherst) of the NISAR science team using data from the\u00a0<a href=\"https:\/\/www.earthdata.nasa.gov\/data\/catalog\/asf-nisar-l2-gcov-beta-v1-1\" rel=\"noopener\">NISAR GCOV product<\/a>, and prepared for NASA Earth Observatory by Michala Garrison.
