Climatological Comparative Meteorological Summary Dashboard
Aerodrome climatological information prepared in accordance with ICAO (Annex 3) and WMO (WMO No.49 vol.2) guidelines
Decadal Aerodrome Significant Weather Climatology
Model G - Frequencies (percent) of occurrence of present weather phenomena
Decadal Aerodrome Prevailing Wind Climatology
Model D - Frequencies (percent) of occurrence of concurrent wind direction (in 30° sectors) and speed (in knots) within specified ranges
Decadal Aerodrome Temperature Climatology
Model E - Frequencies (percent) of the air temperature in specified range of 5°C at specified times
Temperature Frequency 10-Year Trend
Decadal Aerodrome Visibility Climatology
Model B - Frequencies (percent) of visibility (in meters) below specified values at specified time
Visibility 10-Year Avg
Select Visibility Range
Visibility Frequency 10-Year Trend
Note: Percentages shown are exclusive ranges calculated separately
(non-cumulative) as per Model B
Note: Visibility >8000m is not explicitly provided in Model B data.
This value is calculated as 100% - (vis_le_8000m)% for reference purposes.
Decadal Aerodrome RVR Climatology
Model A - Frequencies (percent) of the occurrence of runway visual range / visibility (both in metres) or height of the base of the lowest cloud layer (in feet), of BKN or OVC extent below specified values at specified time
RVR 10-Year Avg
RVR Frequency Cumulative 10-Year Trend

≤1500m
Note:
≤800m includes CAT IIIB to CAT I conditions
(RVR ≤175m to ≤800m).
≤1500m represents Low IMC boundary.
