STATION Network
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

Anemometer calibration
Anemometer calibration
Current meter calibration
SITING Most of station are located in populated areas Problem: - Violation of technical corridor - Relocation of stations - Land for new stations
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.
METADATA - Description of landscape around the station in radius of 300m, 3000m, and 8000-10000m. Record all changes in landscape around the station. - Description of garden and location of observing instruments in the garden.
METADATA - Description of horizon line at the station. - Instruction how to go to the station. - Station staff: number of staff, education, staff change.
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.
Thank you for attention!
