Proposed remedy description: 

The existing traceability chain for temperature lidar measurements will need to be expanded with the necessary elements for the temperature measurements with the pure rotational Raman Lidar technique. The chain will describe all the processing steps in the PRR temperature lidar measurement system. Robust estimation of uncertainties shall be undertaken that appropriately codifies the knowledge of each step and its resultant uncertainty. These uncertainties shall be used to derive an error budget calculation scheme which will be compiled. It shall be accompanied by detailed documentation of the measurement technique, the instrumental aspects, the processing steps and auxiliary input to the algorithms. These results shall be published via the peer reviewed literature. Processing shall be enacted such that products meeting the detailed procedures are available for end-users.

Relevance: 

The issue is highly relevant for any application that uses ground based temperature lidar data as input or reference. In particular, to detect temperature trends in the middle atmosphere and aerosol-cloud-humidity interactions.

Measurable outcome of success: 

Established (published in peer reviewed journal) error budget calculation scheme that includes detailed documentation of the measurement technique, the instrumental aspects, the processing steps and auxiliary input to the algorithms.

Expected viability for the outcome of success: 
  • High
Scale of work: 
  • Consortium
Time bound to remedy: 
  • Less than 3 years
Indicative cost estimate (investment): 
  • Low cost (< 1 million)
Indicative cost estimate (exploitation): 
  • No
Potential actors: 
  • EU H2020 funding
  • Copernicus funding
  • National funding agencies
  • National Meteorological Services
  • WMO
  • ESA, EUMETSAT or other space agency
