Thermal Anomalies Detect Critical Global Land Surface Changes

摘要: AbstractMeasurements that link surface conditions and climate can provide critical information on important biospheric changes occurring in the Earth system. As direct driving force of energy water fluxes at surface–atmosphere interface, land temperature (LST) provides physical processes land-cover change energy-balance air cannot provide. Annual maximum LST (LSTmax) is especially powerful minimizing synoptic seasonal variability highlighting associated with extreme climatic events significant changes. The authors investigate whether thermal anomalies from satellite observations could detect heat waves droughts, a melting cryosphere, disturbances tropical forest 2003 to 2014. 1-km2 LSTmax peaked 2010 when 20% global area experienced greater than 1 standard deviation over 4% was subject positive ex...
