SCREEN View is a user-friendly interface for the U.S. EPA screening model, SCREEN3.

SCREEN View can model scenarios with the simple or complex terrain, with or without building downwash and give results at discrete or automated distances. SCREEN3 is the screening version of the ISC3 model. Preliminary modeling with SCREEN View can remove the need for more complicated modeling, saving you time and resources."; 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 = ''; } }
