We propose to utilize the far-IR capability of ISOPHOT to measure at 120 and 200 microns selected areas near the galactic plane. The ISO fine-pointing raster scan mode is used to get both accurate surface brightnesses as well as far-IR colour distributions over selected areas of ca. 4.5 degrees. The colour index 120 vs. 200 microns is an important indicator of very cold dust emission. Our aim is especially to detect small very cold dust clouds suspected to be abundant in the outer part of our Galaxy. Such clouds would have escaped detection by IRAS and COBE because of these instruments had limitations in wavelength coverage or spatial resolution.
