Remote sensing model for CO2 flux in wheat fields

摘要

In this paper we presented a model for calculating CO$-2$/ flux in the wheat field based on field simulate test. We adopted crop transpiration as 'information picker' of CO$- 2$/ flux instead of the potential evaporation and crop water stress index. Another crucial factor is leaf index and air vapor saturation deficit. Experimental coefficient is equal to 1/58. Calculating values have a good agreement with real measurements. The model is useful to estimate regional distribution of CO$-2$/ flux.
