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

Ø Meteostation Ø Towers

(meteo, TV and other)

Ø Radiosonde Ø Remote sensing

• Satellite
• Ground base

Only near surface measurements Difficult, influence itself etc…. Low resolution in ABL Not resolve ABL Difficult access, few points

Tools for observation in ABL

Sounding ¡in ¡ABL ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡ ¡(SODAR ¡LATAN-­‑3) ¡

Sound impulses Reflected signal Non homogeneities

Example of sounding data (echogramm) and wind profiles

Microwave temperature profiler MTP-5

Example data of Meteorological Temperature Profiler MTP-5

Ultrasonic anemometer
