LAS MkII Large Aperture Scintillometer Heat uxes and evaporation at the Earth’s surface are of great importance to the elds of meteorology and hydrology. The LAS MkII Scintillometer is Kipp & Zonen’s solution for long term unattended monitoring of Cn² and heat uxes within the planetary boundary layer. Sensible heat ux causes a temperature dierence within the atmosphere; its eects are detectable by measuring ambient temperature at two heights. Latent-heat ux is the result of the evaporation of water or transpiration by vegetation. For this reason, this ux is often referred to as...

LAS MkII large aperture scintillometer is designed to oer easy installation, conguration and operation, requiring only limited maintenance. The LAS MkII can be installed and congured using its built-in display and key-pad without the need for any extra equipment. This prevents the inconvenience of carrying additional instruments to the site of installation. The LAS MkII has a built-in data logger and digital outputs for direct PC connection. Real time measurements are shown on the display. The Cn² data is also available as an analogue output to be recorded using virtually any type of data...
