João Martins (IPMA / LSA SAF) - Land Surface Temperature and Heatwave monitoring


João Martins talks about using Land Surface Temperature (LST) in heatwave monitoring using LSA SAF datasets. 




Heat and water stress leave clear signatures on land surface variables that can be monitored from space. The LSA SAF has been providing satellite datasets and products that allow the characterization of the surface energy budget and the monitoring of vegetation growth and stress. We will show that combining information on the surface temperature diurnal cycle and on vegetation state provides a different perspective on the spatial extent and time evolution of droughts and heatwaves, and reveals underlying soil vegetation-atmosphere feedbacks.
