Scientific paper

We propose a 200ksec LETGS/HRC observation of NGC3227, a bright, nearby AGN, coordinated with Suzaku monitoring and HST UV spectra. NGC3227 seems to have a distant, dusty, 'lukewarm' Warm Absorber {WA}, AND a smaller, high ionization, WA. For these WAs an LETGS grating spectrum will determine: ionization parameter, NH, 'b'-parameter, metal ratios and dust-specific features. The WA location will be known from Suzaku monitoring; together Chandra and Suzaku observations determine the mass loss rate. A joint HST/COS UV spectrum gives absolute metallicity and velocity and covering factor. With the WAs well characterized, NGC3227 joins two other WAs to span M BH - L/L Edd space, allowing tests of AGN-galaxy feedback models.;
