4 STATION Network

5 Meteorological network of stations Total 174 stations, divided into 3 classes Class 1: Weather watch: 24/24 hrs Observation parameters: Wind (direction & speed), Rain fall, Air pressure, Air Temperature, Humidity, Sunshine, Evaporations, Land Temperature (ground and deep layers); Cloud, Visibility, Ground conditions, Radiation (at some stations). Data collection & transmission: 8 times/day Class 2: Same as class 1, but not doing the observation of radiation, air pressure (at some stations). Data collection & transmission: 4 times/day Class 3: Same as class 2, but not doing the observation of air pressure. Data

16 Rain gauge calibration

17 Anemometer calibration

18 Anemometer calibration

19 Current meter calibration

20 SITING Most of station are located in populated areas Problem: - Violation of technical corridor - Relocation of stations - Land for new stations

21 METADATA Technical documentation (station book): one at each station, one in network management center Contents of station book -Site specifications: i location map, longitude, latitude, pictures (at least from two sides), elevation above sea level, horizontal visibility. - Station history and duty.

22 METADATA - Description of landscape around the station in radius of 300m, 3000m, and m. Record all changes in landscape around the station. - Description of garden and location of observing instruments in the garden.

23 METADATA - Description of horizon line at the station. - Instruction how to go to the station. - Station staff: number of staff, education, staff change.

24 METADATA - Instrument: number of instruments in use and spare, technical specifications, calibration time. - Every supervision visit to the station will be recorded in this book with comments and recommendations of head of supervision team or expert.
