System for atmospheric boundary layer monitoring in Moscow region - PowerPoint PPT Presentation

System for atmospheric boundary layer monitoring in Moscow region Kurbatov G.A. 1 , Smirnova M.M. 2 1 – Moscow state university, Physical department 2 – Hydrometcentre of Russia

Tools for observation in ABL Only near surface measurements Ø Meteostation Ø Towers Difficult, influence itself etc … . (meteo, TV and other) Ø Radiosonde Low resolution in ABL Ø Remote sensing Not resolve ABL • Satellite • Ground base Difficult access, few points

Sounding ¡in ¡ABL ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡(SODAR ¡LATAN-­‑3) ¡ Non homogeneities Sound impulses Reflected signal

Example of sounding data (echogramm) and wind profiles
