We investigated the dust emissivity at far-infrared wavelengths using a method which reproduces ISOPHOT temperature and optical depth values combining ISOPHOT and IRAS far-infrared data. A sample of clouds was analysed formerly (Kiss et al., 2004) and the method was found to be reliably applicable, allowing us to extend the sample of clouds appropriate for such investigations. We examined a new sample of clouds for which ISOPHOT measurements were made at only one wavelength, to make use of these data in completing our knowledge on dust emissivity properties.
