Introduction
============

WASP-43b is a giant gas planet that has been selected as a JWST target because it orbits a near-solar abundance K7V star (T$_{\rm eff}= 4500$K) at an orbital distance of $a\approx 0.0153$au in 0.813days (). Its atmosphere can therefore be well characterised through transmission spectroscopy and thermal emission measurements. The dayside of WASP-43b is suggested to have a black-body equivalent temperature of $\approx 1700\pm200$K and an equilibrium temperature of T$_{\rm eq}=1400$K (@2014ApJ...781..116B). With a planetary mass of 1.78$\pm$0.01 M$_{\rm J}$ and a radius of R$_{\rm P}=0.93\pm 0.09$R$_{\rm Jup}$ (), its bulk density is 2.744$\pm 0.4$ g cm$^{-3}$. Applying retrieval approaches, (@2014ApJ...793L..27K [@2017AJ....153...68S]) and CO (@2016ApJ...829...52F) are suggested to be present in the atmospheric gas that is accessible from thermal emission (but no as of yet). A comprehensive summary of observational results for WASP-43b can be found in [@2017AJ....153...68S]
