Abstract :
The authors present a new index for mapping and estimating the crop residue cover fraction: the MSACRI (Modified Soil Adjusted Crop Residue Index). This index exploits the mid infrared channels: 1.55 μm to 1.75 μm and 2.10 μm to 2.35 μm. Compared to the visible, these channels are characterized by large transparence in relation to atmospheric constituents. In extreme atmospheric conditions, the MSACRI is subject to a slight reduction of approximately 4%. It offers better discrimination of soils/residue and shows quite good dynamics in the presence of residue with average values close to ±0.03 for bare soil and close to 0.70 for full cover residue
