Dmitry Kiktev Hydrometcentre of Russia / Roshydromet Observational data for Sochi-2014 (project FROST-20 14) COSMO GM 2 Septemer 2013, Sibiu, Romania
Today’s network of meteorological stations in the region of Sochi
The Olympic sport venues • Each venue has 1 basic station and 1-4 supplementary sport stations
Current Instrumentul Setup (AMSs and Sensors Installed): Roshydromet’s stations
Current Instrumentul Setup (AMSs and Sensors Installed): IRAM’s Stationsat the sport venues Basic frequency of observations - 10-minutes; 1-minute observations - for prec intensity, visibility, cloud base, wind gusts
Current Instrumentul Setup (AMSs and Sensors Installed):Roza-Khutor - Alpine Skiing Venue
Current Instrumentul Setup (AMSs and Sensors Installed) : «Meteofon» stations at the towers of mobile communication Issues related: Nonstandard height; precipitation measurements
Quality Control of station observations At the moment implemented only for operational data (series to be controlled) Parameters: T, humidity, wind, Pmsl Components: - Check of limits; Spatial control - for observations at 00, 03, 06 ..21 UTC; Temporal control – for 10-minute observations; QC with respect to COSMO-2.2 forecasts (works better for temperature than for humidity); Manual control
QC flags are presented as a composition of several digits: - low-order (rightmost) digit – manual control; - the 2nd digit from the right – spatial control using approach by Steinaker et al, 2000; - the 3rd digit from the right – temporal control and control with respect to the model forecast; - the 4th digit from the right – reserve.Each digit can take the following values: 0 - no control (default) 1- suspicious 5 - OK 9 – rejectedExamples: e.g., 0010, 0001, 0900 etc.
- Observation data are available from the FROST-2014 ftp-server. - XML-description for the station data is available at http://frost2014.meteoinfo.ru/doc.- Update period for the station observation data at the project server is 10 min- Raw data (volume files) from the Sochi Doppler radar in IRIS format are available at the project sever and updated every 10 minutes- Temperature/Humidity (HATPRO and Scintec-3000) and Wind (Scintec-3000) profilers data to be available at the project server during the Olympic winter.
Snow Density Measurements During snowfalls manual snow density measurements are curried out by the party of anti-avalunch service in Krasnaya Polyana. According to AMS observations there were precipitation intensities up to 30 cm/hour at Roza-Khutor.
