A Basis for Improving Numerical Forecasting in the Gulf Area by Assimilating Doppler Radar Radial Winds
3D-Var Data Assimilation Doppler Winds Errors NWP
2013/3/6
An approach to assimilate Doppler radar radial winds into a high resolution Numerical Weather Prediction (NWP) model using 3D-Var system is described. We discuss the types of errors that occur in rada...
Characterization of the precipitation in southwestern part of Greece with X-band Doppler radar, 2-D video disdrometer and rain gauges
precipitation X-band Doppler radar
2010/1/27
We document precipitation in the southwestern part of Greece with the National Observatory of Athens (NOA) X-band radar, NOA 2D video disdrometer and a network of rain gauges. The observations were co...
