The Gemini Planet Imager (GPI) is a near-infrared instrument that usesAdaptive Optics (AO), a coronagraph, and advanced data processing techniques toachieve very high contrast images of exoplanets. The GPI Exoplanet Survey(GPIES) is a 600 stars campaign aiming at detecting and characterizing young,massive and self-luminous exoplanets at large orbital distances >5 au. Scienceobservations are taken simultaneously with environmental data revealinginformation about the turbulence in the telescope environment as well aslimitations of GPI's AO system. Previous work has shown that the timescale ofthe turbulence, Tau0, is a strong predictor of AO performance, however ananalysis of the dome turbulence on AO performance has not been done before.Here, we study correlations between image contrast and residual wavefront error(WFE) with temperature measurements from multiple locations inside and outsidethe dome. Our analysis revealed GPI's performance is most correlated with thetemperature difference between the primary mirror of the telescope and theoutside air. We also assess the impact of the current temperature control andventilation strategy at Gemini South (GS).
