Methods

1- Site Measurements:

Collect site measurements to understand the links between the belowground and above ground processes. For example, information about soil temperature and moisture, soil physical properties, and microbial activities can help understanding the observed changes in vegetation phenology.

2- Remote Sensing:

Remote sensing for terrestrial ecosystem functions: Modeling ecosystem fluxes at various scales. Climatic variables influence on ecosystem functions. I use site observations and remote sensing data to investigate these questions.

3- Land surface models:

Modeling biogeochemical processes at various scales using land surface model. Using site data, such as FLUXNET observations and allometric measurements, can be used to calibrate and validate land surface models. Moreover, land surface models can be improved by implementing new schemes, such as dynamic phenology and rooting depth.
