Explanation:

a - Automated sensor, measured data are usually included into meteorological reports automatically.

m - Manual measurement/observation, measured/observed data are included into meteorological reports by observer based on his/her own (subjective) observation.

a/m - Combination, automated sensor and/or manual measurement/observation, manually measured/observed data are included into meteorological reports only during operational hours of the meteorological station. In relation to the prevailing visibility and cloudiness, the automated measurements of the visibility and cloud base height (vertical visibility) are used as supplementary information to the human observation.

3.5.3.4 Location of selected meteorological instruments is stated in para. GEN 3.5.3.2. Other measuring instruments are usually located near the meteorological station in the meteorological garden. Observer makes observation during operational hours from the meteorological station (see para. GEN 3.5.3.2).
3.5.3.5 METAR and SPECI are prepared and issued during operational hours of the meteorological station. Frequency of issuing and type of meteorological reports are listed in para. GEN 3.5.3.2.
3.5.3.6 At Piešťany aerodrome measurements are performed by an automatic meteorological station outside of its hours of operation. On such measurements the automatically compiled reports (AUTO METAR) are based. Automatically compiled reports contain only selected meteorological elements:
  1. surface wind direction;

  2. surface wind speed;

  3. visibility;

  4. runway visual range;

  5. weather phenomena;

  6. amount and height of cloud base or vertical visibility;

  7. air temperature;

  8. dew point and

  9. pressure.

3.5.3.7 At Bratislava/M. R. Štefánik, Košice, Piešťany, Sliač, Poprad-Tatry and Žilina aerodromes both the meteorological measurements and the distribution of the local meteorological reports are integrated into aerodrome weather observing system (AWOS), which allows to display the meteorological data and local routine and special reports to the local ATS units.
3.5.3.8 All data from MET REPORT and SPECIAL reports as well as values of meteorological elements, which are automatically measured and monitored on meteorological systems, are logged.
3.5.3.9 Surface wind measurement and reporting
3.5.3.9.1 Surface wind parameters are measured at a height of 10 m. Location of anemometers is shown on the chart of the relevant aerodrome or in the table, in para. GEN 3.5.3.2. Remote displays of the anemometers are in the meteorological station, TWR and APP.
3.5.3.9.2 Values of wind elements included in METAR and SPECI reports are the averages during a 10 minutes time interval, values in MET REPORT and SPECIAL reports are the averages during a 2 minutes interval.
3.5.3.10 Measurement of visibility and runway visual range
3.5.3.10.1 Visibility is visually estimated by observer from the meteorological stations using natural characteristics of terrain, natural orientation points in the surroundings or the light sources. At Bratislava/M. R. Štefánik, Poprad-Tatry, Piešťany and Žilina aerodromes for the determination of visibility are also used data obtained from the measurements of forward scattermeters. At Košice aerodrome for the determination of visibility are used the data obtained from the measurements of transmissometers and/or forward scattermeters. At Sliač aerodrome for the determination of visibility are used the data obtained from the measurements of transmissometers.
3.5.3.10.2 In local routine and special reports and METAR and SPECI the visibility is reported as prevailing visibility i.e. the visibility reached or exceeded within at least half of the horizon circle or within at least half of the surface of the aerodrome.
3.5.3.10.3 When the visibility is not same in different directions and
  1. when the lowest visibility differs from the prevailing visibility, and less than 1 500 m or less than 50 % of the prevailing visibility and lower than 5 000 m, the lowest visibility observed is also reported and its general direction in relation to the reference point of the aerodrome indicated by reference to one of the eight points of the compass. If the lowest visibility is observed in more than one direction, then the most operationally significant direction is reported;

  2. when the visibility is fluctuating rapidly, and the prevailing visibility cannot be determined, only the lowest visibility is reported (without indication of direction).

3.5.3.10.4 Runway visual range (RVR) is measured at Bratislava/M. R. Štefánik, Košice, Piešťany, Sliač, Žilina and Poprad-Tatry aerodromes. Measuring sites are shown on the chart of the relevant aerodrome. RVR is automatically evaluated by defined procedures from transmissometers or forward scattermeters measurements and computed as if 100 % intensity runway edge lights were on. Current 1-minute RVR values are available on the displays at TWR and APP units. 
3.5.3.10.5 Lower and upper limits for reporting of the runway visual range are:

3.5.3.11 Cloud observing, cloud base height measurement
3.5.3.11.1 Amount and type of cloud (CB and TCU only) are observed visually from meteorological station area. In reports the cloud groups are expressed only when the operationally significant clouds representative for aerodrome and its vicinity occurred (approximately within the diameter of 16 km from the aerodrome reference point).

3.5.3.11.2 Cloud base height is measured by ceilometers, their locations are listed in para. GEN 3.5.3.2. Measurements by these instruments are carried out continuously and the actual values are available at TWR and APP.
3.5.3.11.3 When operationally significant clouds are observed the meteorological messages contain also information about other clouds or cloud layers those high of cloud base is no more than 10 000 ft (3 000 m). If no operationally significant clouds are observed at aerodrome and its vicinity abbreviation CAVOK or NSC (No Significant Clouds) are used in the meteorological reports.
3.5.3.11.4 Amount of clouds and cloud layers are referred to the entire sky (sphere). In AUTO METAR reports, the cloud amount is estimated by ceilometer 30 - minute period lasting measurements.
3.5.3.11.5 In AUTO METAR reports, the type of cloud CB or TCU is not indicated from technical reasons.

3.5.4  Types of services

Meteorological offices providing meteorological services to aviation are created at Bratislava/M. R. Štefánik and Košice aerodromes.

3.5.9  Other automated meteorological services

3.5.9.1 Operators can obtain meteorological information and flight documentation also by Integrated Briefing Automated Facility (IBAF). System IBAF is available H24 for registered users by means of:
  1. self-briefing terminals at international airports: Bratislava/M. R. Štefánik, Košice, Piešťany, Sliač, Poprad-Tatry and Žilina (see para. GEN 3.1.5.1) or

  2. Internet, web address http://www.lps.sk/ibaf.

Both mentioned systems are operated by LPS SR, š. p. (ATS provider). However the meteorological information for system IBAF is provided by Aeronautical Meteorological Service of SHMI according to agreement with LPS SR, š. p.

3.5.9.2 By means of IBAF the meteorological information are provided in the form of flight documentation based on the specific user requirements stated during the flight plan writing.

Content of the flight documentation depends on the following parameters defined by user:

  1. ICAO aerodrome abbreviations of the departure, destination and alternate aerodromes define range of METAR/SPECI reports and aerodrome forecasts TAF*), supplemented with information for take-off (for aerodrome of departure): wind, temperature and humidity at FL 050, 100, 140 and 180. SIGMET, AIRMET information and air reports are inserted into flight documentation automatically according to the regions corresponding to ICAO aerodrome abbreviations.

  2. Region (Africa, Europe, Asia and NAT) determining a geographical area for the chart products (significant weather charts and upper wind and temperature charts).

  3. Significant weather charts as option for the insertion of such a chart into flight documentation. When region Europe is selected the mid-level significant weather chart (SWM, FL 100 - 450) is inserted into flight documentation. When other regions are selected the high-level significant weather chart (SWH, FL 250 - 630) is inserted into flight documentation.

  4. Upper wind and temperature chart as option for the insertion of upper wind and temperature charts into flight documentation according to selected region and flight level (FL 050, 100, 140, 180, 240, 270, 300, 320, 340, 360, 390, 450 and 530).

  5. Low level wind and temperature chart as option for the insertion of the vertical wind cross-section chart for levels 0, 300, 600, 900 and 1 200 m and a height of the freezing level along the fixed stated routes:
