to generate the clutter map 10 ZDR/PhiDP offset correction Using the birdbath method introduced by Gorgucci et al. (1999): Thresholds related to light rain are set: • VPs containing 2 or more consecutive bins of Z DR in the rain region, With corresponding values of: • 5 dBZ < Z � < 30 dBZ ρ �V > 0.98

following a cloudy start, then light rain on the 11th moved slowly southwards, with brighter weather following into the north. The 12th was generally cloudy with some rain at times. 13th to 20th High pressure dominated, giving mostly dry sunny weather. The 13th and 14th were dry and mostly sunny

on technology driven systems, it is only in The likelihood Whilst severe events leading to total failure of GNSS are rare, relatively common space weather events can still have minor disruptions on navigation systems, which can still be significant to an industry where navigation is at the centre of its

likely that this year will see a continuation of the post-2007 sea ice conditions, whereby every year since 2007 (inclusive) has recorded a September extent lower than every year before 2007. Each year, scientific centres around the world submit predictions of September Arctic sea ice extent

for Tuesday and Wednesday. Weather over past Coronations Data from the Met Office archive shows that past coronations back to Edward VII have been mixed when it comes to the weather.
