It provides extensions for BEAM, which allow accomplishing the following tasks: Noise reduction: Removes the vertical striping in CHRIS response-corrected images caused by the slit effect and a superposition of high-frequency noise. Cloud screening: Marks cloudy pixels in CHRIS noise-corrected images; the cloud screening algorithm provides cloud probability and abundances for each pixel. Atmospheric correction: Provides a surface reflectance retrieval algorithm. The method applies to noise-corrected radiance images with (or without) a probabilistic cloud mask as generated by the cloud screening algorithm and more."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
