Ground Segment for a L5 SWE Monitor Operational Mission L5 Consortium meeting, London, May 11 th - 14 th Gareth LAWRENCE, Alastair PIDGEON Abstract The Operational Space Weather Monitoring mission will launch and operate in Space a comprehensive payload of purpose-designed sensors, but the key

. At such temperatures, the cloud particles forming in the contrail freeze almost instantaneously to leave a cloud of small ice crystals. The temperature conditions required for contrail formation typically occur at altitudes of 30,000ft and above, the typical altitude for many airliners in cruising flight. They may

thousand one hundred metres' RVR tendency (U = increasing; D = decreasing; N = no change; not reported in UK at present) may be added after figure e.g. R27R/1100D. P1500 = more than 1500 m; M0050 = less than 50 m. Significant variations — example : R24/0950V1100, i.e. varying between two values

Factsheet 3 of 6 Version date: Dec 2019 Risk management of climate thresholds and irreversible change: Ice Sheets What is the nature of the threshold? Ice sheets have been found to exist in different equilibrium states, and if they melt beyond a certain threshold, they may collapse into a no-ice
