Abstract. The moisture content of vegetation canopies controls various ecosystem processes such as plant productivity, transpiration, mortality, and flammability. Leaf (here defined the ratio leaf water mass to dry biomass, or live-fuel content, LFMC) is a property that frequently used estimate flammability danger fire occurrence spread, widely measured at field sites around globe. LFMC can be retrieved from satellite observations in visible infrared domain electromagnetic spectrum, which...
Abstract. Vegetation attenuates the microwave emission from land surface. The strength of this attenuation is quantified in models terms parameter vegetation optical depth (VOD) and influenced by mass, structure, water content, observation wavelength. Earth satellite sensors operating frequencies are used for global VOD retrievals, enabling monitoring at large scales. has been to determine above-ground biomass, monitor phenology, or estimate status. can be also constraining surface modelling...

Climate change leads to a of precipitation frequency and quantity as well increased temperature inducing extreme weather events like floods but also more intensive longer drought periods.The response the vegetation these trends is high interest because regulates interception, transpiration water storage which important for plant productivity, agriculture, carbon cycling danger wild fire occurrence. Reduced in combination with lead stressed might not only behave different regards...
