Abstract

A Method to Evaluate Data Availability of Doppler Lidar: the European Case

Introduction

Remote Sensors data availability at a site is one key parameter when deploying such type of instrument. As the cup anemometer’s availability is sensitive to icing, Sodar and Lidar data availability also depend on certain atmospheric conditions.

Approach

Recent advances in Lidar modeling combined with the exploitation of large atmospheric aerosol concentration databases now permits to estimate the instrument availability at any onshore and near-shore site of the world.

Main body of abstract

The Lidar signal modeling takes into account the instrument hardware and signal processing specificities, as well as the propagation of pulsed laser light through the atmospheric layers. The atmospheric content is provided by the network of weather stations available all around the world. Influential parameters for the Lidar beam propagation are extracted from these stations.
This atmospheric information is also given with a reasonable time frame and spatial scale, making such a data availability modeling potentially of high interest for planning an optimal use of the Lidar instrument over the year and locations.
We propose to present the methodology employed as well as an example mapping of Lidar availability over Europe or a selection of countries in Europe. Measurement campaigns with vertical profilers and long-range scanning Lidars at selected locations will be used to validate the simulation and estimate the remaining uncertainties between simulated and observed Lidar availability.

Conclusion

Lidar modeling techniques allied with atmospheric data provided by weather stations are used to estimate the remote sensor availability to some extent. This is particularly useful when planning a resource assessment campaign and selecting future locations for a remote sensor.


Learning objectives
The audience will gain knowledge in the sensitivity of remote sensor data availability to atmospheric conditions. A mapping of data availability for Doppler Lidars in Europe will be presented. The methodology, along with its pros and cons, will be explained to encourage further applications and validations
