<p class="MsoNormal"><span lang="EN-US">Thanks for the reply, I tried with that output (QSIAB), and also I tried the QIBAB and QIDAB for the same surface (the ground floor), but I get the same value on QIDAB as in QSIAB, meaning that all the incident radiation
is diffuse. Am I right? Is there a need to adjust some parameter? I saw something about GEOSURF parameter, but I do not have it clear how to justifiy what number to put there. <o:p></o:p></span></p>
