商品詳細介紹Product Introduction

Introduction
Heat fluxes and evaporation at the Earth’s surface are of great importance to the fields of meteorology and hydrology. 

Sensible heat flux is the transfer of heat between the Earth’s  surface and the air above, due to a temperature difference between them. The direction of this flux can be seen by measuring temperature at two heights. Latent heat flux is the result of the evaporation of water or transpiration by vegetation. For this reason, this flux is often referred to as evapo-transpiration (ET). Both fluxes are major components 
of the Earth’s surface energy budget.  

Accurate continuous measurement of these parameters is often required for research projects and monitoring applications. Where the measurements need to be done on a field or landscape scale, or for validating satellite data, the traditional in-situ point measurement techniques are not sufficient. 

The Kipp & Zonen LAS MkII is a large aperture scintillometer designed to provide continuous measurements of sensible heat flux and turbulence statistics (Cn²) over long distances, from 100 m up to 4.5 km, for energy balance studies and evaporation monitoring.

Thanks to the extended range, scintillometer measurements can be compared to the typical pixel sizes of satellite-based instruments for ground validation applications.
