摘要

The aim of this study is to understand which vegetation indices represent good proxies for gross primary productivity (GPP) and whether they are able to capture the effect of drought on GPP in a temperate dry heathland ecosystem. To this end, a meteorological tower was equipped with both eddy covariance instrumentation to measure CO2 fluxes as well as with an optical sensor to calculate several gr...
