Validation of MODIS and GEOV1 fPAR Products in a Boreal Forest Site in Finland

Evaluation of MODIS LAI/FPAR Product Collection 6. Part 2: Validation and Intercomparison

The aim of this paper is to assess the latest version of the MODIS LAI/FPAR product (MOD15A2H), namely Collection 6 (C6). We comprehensively evaluate this product through three approaches: validation with field measurements, intercomparison with other LAI/FPAR products and comparison with climate variables. Comparisons between ground measurements and C6, as well as C5 LAI/FPAR indicate: (1) MOD...

Spatial and temporal validation of the MODIS LAI and FPAR products across a boreal forest wildfire chronosequence

Estimation of leaf area index and the fraction of absorbed photosynthetically active radiation in a boreal forest

The aim of this dissertation is to assess the accuracy of different ground reference methods used to validate satellite based leaf area index (LAI) and the fraction of absorbed photosynthetically active radiation (fPAR) products. LAI and fPAR are strongly linked, although they principally and practically measure different properties: LAI quantifies the areal interphase between soil and atmosphe...

Assessment of MODIS, MERIS, GEOV1 FPAR Products over Northern China with Ground Measured Data and by Analyzing Residential Effect in Mixed Pixel

Fraction of Photosynthetically Active Radiation (FPAR) is a critical parameter in land surface energy balance and climate modeling. Several global FPAR products are available, but these still require considerable assessment and validation due to low spatial resolution. Three major FPAR products that have covered China and provided continuous time series data—MODIS, MERIS and GEOV1—were assessed...

Validation of the MODIS LAI Product in Coniferous Forest of Ruokolahti, Finland

Leaf area index collected in a needle-leaf forest site near Ruokolahti, Finland, during a field campaign in June 14-21, 2000, was used to validate Moderate Resolution Imaging Spectroradiometer (MODIS) LAI and FPAR algorithm. The field LAI data was first related to 30m resolution Enhanced Thermal Mapper Plus (ETM+) images using empirical methods to create a high resolution LAI map. It shows that...
