Various types of photoionised outflows are observed from AGN. A 200 ksXRISM PV observation is scheduled to study the nature of the outflows inNGC 3783 the best case for this purpose. We propose joint observationsof XMM-Newton NuSTAR HST and Swift. XMM/RGS characterises lowerionised absorbers in soft X-rays. In combination with the higher ionisedones revealed by XRISM we can study all absorbers comprehensively.XMM/EPIC and NuSTAR determine the spectral energy distribution andconstrain the continuum. HST accurately measures outflow velocity fromUV absorption lines. Swift observations preceding XRISM brings the fluxhistory for photoionisation modelling of the variable absorbers. [truncated!
