We have taken significant step toward the understanding exoplanetary atmospheres. We took the advantage of the high photometric precision and long temporal coverage the CoRoT and Kepler light curve offer to carry out studies dedicated to the analysis of the atmospheric properties of close-in planets. With the PHOENIX model atmosphere we have calculated irradiation effects under varying incident angles which adds an entire new dimension to the models for individual planets for which we have phase light curves and precise photometry from Kepler. We have calculated theoretical phase fluxes using the PHOENIX atmosphere code (Allard et al 2013) and compared to published phase curves and secondary transit of CoRoT and Kepler planets. We explored different assumptions concerning the redistribution of absorbed stellar flux over the planet's day hemispheres. Our study gives valuable information regarding the cloud and thermal properties of those planets.
