| Resumo | This paper presents partial results of a four year research project carried out to assess the feasibility of using TM/Landsat data to monitor the water quality of an eutrophic tropical reservoir. Eighteen in situ water quality data collection missions were performed concurrently to Landsat overpasses from May 1989 to October 1991. During this period six cloud free Landsat scenes were acquired. This paper will focus on the statistical analyses of the in situ and remotely sensed date collected in five missions. TM/Landsat data were converted into reflectance values (spectral variables)and correlation analyses were applied to assess their relationship with the water optically active components (Chlorophyll a + pheophytin a, Total suspended solids, Inorganic suspended matter, organic suspended matter). The correlation was run for 4 different sample sets. 1- the whole reservoir (30 samples); Tiete inlet; Piracicaba inlet (10 samples); Main body (10 samples), the correlation among 98 pair of variables was investigated. Taking into account that the correlation was tested for 5 different dates (three winter dates and two summer dates)and for 4 different sample sets, 1960 possible correlations between limnological data and remotely sensed data were studied. Preliminary results showed that, from the whole set of correlations, only 30 of the 1176 winter possible correlations were statistically significant. The results confirmed published data elsewhere since for the winter time, 58 of the statistically significant correlations occurrred between inorganic matter concentration and TM3 remotely sensed reflectance. For the summer time, 80 of the statistically significant correlation were found between inorganic matter concentration and TM3 reflectance as well. Total chlorophyll although being an optically active variable was not consistently related to any spectral variable, confirming the problems of chlorophyll retrieval for case 2 waters. |
