Convective boundary layer sensible and latent heat flux lidar observations and towards new model parametrizations

TL;DR

This paper presents lidar observations of wind, temperature, and humidity in the convective boundary layer to evaluate and improve model parametrizations, especially in the entrainment layer.

Contribution

It provides new turbulence-scale lidar data for assessing and developing improved parametrizations of the convective boundary layer.

Findings

Lidar data reveals detailed turbulence characteristics.

Assessment of existing parametrizations shows areas for improvement.

Results support development of more accurate boundary layer models.

Abstract

Model parametrizations in the convective boundary layer are still at work especially in the interfacial layers with the surface and the free troposphere. The present paper reports simultaneous turbulence-scale lidar observations of wind speed, temperature and specific humidity in the convective boundary layer in temperate and semi-arid regions. The collected data are used to assess new parametrizations in particular in the entrainment layer.
