ADM-Aeolus quantification of L2B HLOS wind accuracies for typical wind-shear, aerosol and cloud conditions

This document describes the work done and the results obtained for Work Package (WP) 4 of the Vertical Aeolus Measurement Positioning (VAMP) project. The objective of this WP is to investigate the quality of the Level-2B (L2B) Horizontal projected Line-of-Sight (HLOS) wind results, in case of separate processing of the Mie and Rayleigh channels, and in case they can be combined. Especially the benefit of Mie oversampling
(i.e. having multiple Mie range bins covering a single Rayleigh range bin) will be investigated in conditions with large gradients in for example wind shear (i.e. vertical variation of the horizontal wind components) and optical properties.
This document has been divided in three parts. First, the utilization of Mie Core and
Rayleigh processing outputs as quality indicators is described in sections 3 and 4. Then in section 5 the
LIPAS tool is described in some detail, including the modifications added to it to make it suitable for use in the current project. In section 6 the L2B HLOS information content for the separate and combined Mie and Rayleigh channels is quantified. A summary of the benefits and drawbacks of the proposed sampling scenarios is discussed in sections 7, 8 and 9. Each chapter is concluded with an overview of the findings, conclusions and recommendations. These can be found in sections 3.12 and 10.
