Analysis of the data of in situ observation of spectral reflectance of the polluted cedar leaves and LANDSAT Thematic Mapper (TM) data indicate following interesting features. (1) The level of pollution caused by sulfur dioxide in the forest area can be assessed by the reflectance ratio (NIR/R) of the spectrum of red (R) band (TM band-3) and near infrared (NIR) band (TM band-4) calculated from the LANDSAT TM data. (2) It is possible to visualize the degree of atmospheric pollution by inputting results of the analysis of the LANDSAT TM data, the findings of ground truth and growing conditions of forestal trees together with the results of the chemical anlysis of sulfur dioxide.
