GPP is integrated over the growing season to estimate Net Primary Production (NPP). Growth and maintenance respiration costs for NPP are either accounted for indirectly, e.g. Carnegie-Ames-Stanford Approach (CASA: Potter et al., 1993) and the Moderate Resolution Imaging Spectroradiometer GPP/NPP ...
In recent years, many remote sensing based carbon flux models were developed, such as Glo-PEM [6], C-Fix [7,8], VPM [9], MODIS GPP/NPP algorithm [10], and DCFM [11]. All of these models use air temperature as an input. At many observation stations, the air temperature is ...
