The following is a step by step guide for determining standing wet biomass (to be used for determining BWE) via satellite image analysis for use in the CRNS calibration function (see Eq. 2.​1). This index calculates wet biomass but not dry biomass. As such, the use of remote sensing in this publication to calculate the BWE is dependent on knowledge of crop growth stage and/or existing crop models that can give an estimate of the ratio of water mass to dry mass within the plant. It is important to note that these procedures use images produced by NASA’s Terra satellite (http://​earthexplorer.​usgs.​gov/), specifically the 500 m resolution Moderate Resolution Imaging Spectroradiometer (MODIS).
