[ RASP UK Forecast (Stratus) ]




BLIP Quality Check

To help understand if the RASP forecast is matching the real world, an experimental script has been put together that will compare a RASP 'spot' forecast against a METAR observation (a real-world airfield met observation).

These observations are produced hourly or so.

The following table is a summary for the UK, using the script outlined below the table and map. The table is produced from 09:00 to 18:00 on the hour and every half hour during UK daylight hours.

A spatial map of the reports can be found here.


The following plot will show a running view of the percentage of measures as correct between the forecast and the RASP prediction. Normally for the whole of the UK, 85% or higher indicates RASP is close enough and can be relied upon.


This report: 11:42:59 18/02/2019 for this map view. This run created in 117.61 secs
