He (2014). The dominant native grass species found in the study sites are needleand-thread grass (Stipa comata), western wheat grass (Agropyron smithii), June
grass (Koeleria gracilis) and blue grama (Bouteloua gracilis). Fresh biomass
samples were dried in an oven for 48 h at 60
C and weighed.
8.3 Integration of Remote Sensing Data and Modeling
Approach
The methodology section (Fig. 8.2) starts with a brief overview of the BIOMEBGC model, is followed by the desicritpion of C:N ratio mapping for the study area,
and ends with an assessment of modeling results based on field observations. The
main focuses are on producing a C:N ratio map from MODIS data and on the
comparisons between field-based NPP, the fixed C:N ratio driven modeling results,
and the C:N ratio map driving NPP.
