Hot Jupiters are, and will stay, the best targets for atmospheric characterisation in the years to come. Their 3D structure, however, makes it challenging for atmospheric retrievals to obtain reliable chemical abundances from their spectra. 

JWST now allows unprecedented insights into hog Jupiter atmospheres, and can, in particular, probe their 3D structure through phase curve observations. I will present the NIRSPEC/PRISM phase curve of the hot Jupiter NGTS-10b, covering the 0.5-5.5 microns range. This represents the best panchromatic data of a hot jupiter so far. 

I will discuss the evidence for 3D effects, including the presence of a localised, shifted hot spot on the dayside, the vertical variation of the hot-spot shift and the quenching of chemistry through day-to-night heat transport and the possible presence of clouds. I will further discuss the lessons learned from this in-depth characterisation for atmospheric retrievals.
