6. Application 1: modelling along an elevation gradient
Motivation
In dry inner‐alpine regions, managed grasslands are irrigated.
Climate change raises issues about future water availability.
Which are the effects of the elevation gradient on SWE, SWC, ET,
grassland productivity?
Della Chiesa et al., Modeling changes in grassland hydrological cycling
along an elevational gradient in the Alps,
Ecohydrology, 2014
.
12. Application 2: land surface temperature
Motivation
LST is a key variable of the surface energy budget.
Improving its estimation in energy budget models can improve fluxes partitioning estimation.
Which are the factors controlling LST in mountain environments
(i.e. elevation, solar radiation, land cover, soil moisture)?
Bertoldi et al., Topographical and ecohydrological controls
on land surface temperature in an Alpine catchment,
