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.

This report: 09:41:31 25/05/2017 for this map view. This run created in 29.8 secs


Map Key
Green marker means inside thresholds (one metric outside is shown light green).
Yellow marker means two metrics outside thresholds.
Red marker means three metrics outside thresholds.
Blue marker means report not available or similar.

Notes and Observations
EGUO (R) Colerne - METAR report more than six hours old (1511 hours) for EGUO - report not usable.

Table Key
Highlight thresholds: Wind is 30° - Wind Speed is 7 kts - Temperature is 3° C - Cloudbase is 1500 feet - Pressure is 1.6 mb (not reported upon)

Table Averages
Difference Averages: Dry: 0.06° C - Wet: -0.34° C - Wind Speed: -2.07 Knots (RASP High) - Wind Deviation: 65.1 Degrees - Pressure: 0.3 mb
Difference calculations based on actual minus the forecast.
Averages that are greater than +/- 2 Celcius indicates forecast widely differs from actuals.
