Abstract. We present a study of a high spatial resolution raster acquired on-disk with the SUMER (Solar Ultraviolet
Measurements of Emitted Radiation) grating spectrograph on SoHO (the Solar and Heliospheric Observatory) in a polar Coronal
Hole (CH) region. We analyse two EUV emission lines, representing the properties of solar plasma in the low transition re-
gion (TR), O III 703.87 (maximum electron temperature, Te 8 104
K), as well as in the corona, Mg IX 706.02
