3.2 Calibration of the model
As described in section 2.1, ground Leaf Area Index was measured in each field at sites 2, 11 and 14 during SMAPVEX12.
These measurements were divided into datasets to be used for calibration of the Water Cloud Model, and data for validation of model estimated Leaf Area Index. Site 2 was located at the beginning of the first field transect, while sites 11 and 14 were positioned closer together on the second transect.
As such, site 2 was used to calibrate the model leaving both sites 11 and 14 for model validation.
