Today at the EWI building: look out the window!

from Albert Oude Nijhuis

Today we're living in the most polluted area of the world. We even beat China regarding the level of NO2! From OMI (satellite) we get the following map of tropospheric NO2 (trace gas and indicator for pollution intensity):

From the top of EWI building (picture from 21st floor) we can clearly recognize the pollution.

Video Lectures on Polarimetric Radar for Meteorological Purposes

In the Meteorological institute of the University of Bonn on July 2012  a series of six lectures on the use of polarimetric radar for meteorological purposes was given by Dr. A. Ryzhkov from the National Severe Storms Laboratory, Norman, Oklahoma.  Alexander Ryzhkov is one of the world's leading scientists in the field of radar meteorology.

Lecture 3 explains the significance of polarimetric variables, such as differential reflectivity, differential phase, specific differential phase, attenuation and specific attenuation or cross-correlation coefficient and their use in observing the various types of meteorological and non-meteorological scatterers.
