When combined with infrared observations with the Spitzer telescope (3 to 160 ЮМm), the Herschel Space Observatory now fully samples the thermal dust emission up to 500 ЮМm and enables us to better estimate the total infrared-submm energy budget (LTIR) of nearby galaxies. We present new empirical calibrations to estimate resolved and integrated total infrared luminosities from Spitzer and Herschel bands used as monochromatic or combined tracers. ...
