| Abstract: | During the IMGRASS (Inner Mongolia Grassland-Atmosphere-Surface Study ) summercampaign in 1998,the polarization characteristics of reflected sunlight by natural steppe canopies were mea-sured with IAP polarimeter. Two cases were reportd and analyzed herein,one for Leymus chinensis and theother for Carex korshinskii. Polarization degrees of reflected sunlight for the two cases were found to be ob-viously smaller than the published ones for other canopies at similar viewing geometric conditions. And thespecular reflecting characteristics of vegetation were reproduced to some extent for the cases hereof,whichcouldn't be available by photometric measurement alone. In conclusion,as for passive light remote sensingof grassland,polarimetry may be useful for additional information that is not obtainable or difficult to ob-tain from photometry alone,so more effort shoule be done. |
