What was the purpose of Wind Val I?

The objectives for the Wind Val I campaign in 2015 were derived from results, experience and lessons learnt from the last airborne campaign in 2009. The main campaign objectives were to:

  1. Confirm and document the technical performance of the ALADIN Airborne Demonstrator (A2D) lidar and its suitability for the foreseen calibration/validation of ADM-Aeolus
  2. Extend existing datasets on response calibrations over favourable areas for Aeolus calibrations, e.g. ice or land with high surface albedo in nadir-pointing mode
  3. Extend existing datasets on Rayleigh and Mie wind observations. This shall include measurements in highly variable atmospheric conditions (vert./hor.) w.r.t. wind and clouds
  4. Rehearsal for airborne Cal/Val activity after launch with focus on flight
    • Test Aeolus satellite measurement-track predictions and airborne
    • Enhance and test capabilities for quick-look data processing
    • Coordination with other aircrafts and ground validation sites
    • Demonstrate complementarities and synergies between different measurement techniques utilized aboard the same platform, from co-located platforms and on-ground during the campaign
    • Demonstrate the performance and adequacy of the A2D data processing chain for the foreseen Aeolus CAL/VAL campaigns
    • Provide feedback on measurement strategies and procedures of data collection for future campaigns
    • Extend lessons learnt from previous campaigns
  5. Perform at least one flight under the satellite track of TDS-1 to achieve co-located satellite measurements of wind vectors with airborne wind lidars.
