Abstract Details

2017, Master of Arts, University of Toledo, Geography.
In the United States of America, several studies have quantified evapotranspiration (ET) in different ecosystems at a local scale. Accurate and spatially explicit information on ET is rare in small cities like Toledo mainly due to the lack of appropriate tools. A remote sensing ET product from the MODerate Resolution Imaging Spectrometer (MOD16) has been developed. However, its accuracy is not known in and around the ecosystems of Toledo. The main objective of this study was to compare the MOD16 ET product using the data from eddy covariance based Flux Tower of The University of Toledo. Eight day and monthly cumulative ET was calculated from the Flux Tower data to coincide with the MOD16 product over the year 2014. The Flux Tower results showed significant number of missing values in the period of June 26 to September 19 and October 29 to November 13. The 8-day MOD16 ET was not compared for the inconsistencies in seasonal variations. Due to data gaps, only monthly ET of Flux measurement from January to June was compared with the MOD16 ET of all selected places. All places were shown positive relation with Flux observation at the R2 level of more than 0.5 which means that more than 50% data were explained the best fit for the interrelationship among them. The appropriateness of the MOD16 and Flux Tower based ET comparison can be attributed to, among other things, (1) the parameterization of the Penman-Monteith model, (2) Flux Tower measurement errors, and (3) Flux Tower footprint vs. MODIS pixel coverage. MOD16 is important for global inference of ET, but to use it for the water management of Toledo, a locally parameterized and improved product should be developed.
