No low cloud. [ChilboltonObser] RHIs indicate that this thins out somewhat to the west, but still a strong signal from mid-level cloud out to 100km W Chilbolton. Some indications of supercooled liquid. Looking good!#] <FAAMOpsCran> Can Steph send the WAS N2 bottle serial no so I can enter details on the database please. <FAAM_GLUXE> we're now descending to Boscombe, will relay Chilbolton update once com traffic low. Will pass on s/n for N2 cyl once I can get out of my seat! *** TomC (vircuser@twc.ge.man.ac.uk) has joined #APPCLOUDS <TomC> good day [ChilboltonObser] Latest Chilbolton conditions: dry slot between cirrus and mid-level layer cloud is now deeper, cirrus still around same altitude(8000-10000m), but mid-level stuff top 5500-6000m base approx 2500m. This thins out 20-50km W chilbolton, thickening up again further West. [ChilboltonObser] And definately some good signs for supercooled liquid at the top of that altostratus layer [ChilboltonObser] some nice gravity waves here too <TomC> When do you need to decide whther this is one flight or two today ? <FAAM_GLUXE> test <FAAM_GLUXE> Hi Tom, the decision for 1 or 2 flights will be made at 12:00 <FAAM_GLUXE> Jim, you took off with the instructions! The $B431.txt log file isn't logging properly. Some messages are missing. <FAAMOpsCran> Can Keith give DFL Ops an idea of the area they wish to fly in for wave clouds tomorrow. N of Glasgow is a bit vague for flight planning purposes. Also. Refuel may be Prestwick rather than Teeside depending on area <FAAMOpsCran> I think the log file doesn't properly update until you close the session (based on my minimal experience). <FAAM_GLUXE> Please book area Charlie as main and Bravo as backup for tomorrow's flight <FAAM_GLUXE> Captain suggests Newcastle or Teeside as refuel options for tomorrow <FAAM_GLUXE> Doug can you confirm you passed on info ref tomoro & Sat to Helen? <FAAM_GLUXE> test again <TomC> Latest met O meso has middle level cloud persisting until after 3 pm but breaking over your area before 6 pm <JimCR_FAAM> Doug has spoken to Helen, they will try to do both but Saturday is better timewise <FAAM_GLUXE> Tom, do you want us to stay on study untill 1430 or do a refuel? [ChilboltonObser] lidar is seeing patchy liquid embedded in the ice fall streaks at 3500-4000m. RHI shows a very strong return from ice streaks approx 80km W Chilbolton +30dBZ over 2-6km altitude. Closer in more like +10dBZ peak, still fair ice content though + optically thick <JimCR_FAAM> Stephane, the instructions don't have any more instructions about logging. Best bet is to surf the config files but note Doug's comment above <FAAM_GLUXE> Jim, have you found a way to copy/paste the messages? Am trying to feed Chilbolton's updates to Mission Scientist via Core1 server, to reduce radio traffic. [ChilboltonObser] lots of specular reflection from oriented plate crystals in vertical lidar data, estimate liquid top approx -20C so seems sensible. Some evidence of intermittent seeding of altostratus from cirrus above on latest overhead cloud radar data. RHIs show some interesting waves in evaporating ice virga 0-20km W Chilbolton. [ChilboltonObser] supercooled liquid embedded in ice streaks now quite persistent, approx 3500m altitude, sloping gently - maybe something to do with the waves... <FAAM_GLUXE> Hi Tom, *** FAAMOpsDoug (~vircuser@host86-153-16-34.range86-153.btcentralplus.com) has joined #APPCLOUDS <FAAM_GLUXE> Tom, have you made a decision re. staying on area till 14:30 or landing/refuel to extend study? <FAAMOpsDoug> Doug now on this ID, Guy on FAAMOpsCran [ChilboltonObser] From our point of view at Chilbolton the clouds are incredible here now - plane has only done 2 runs so far - seems like best thing is to keep sampling conditions we have til 2.30. What do you reckon? <FAAMOpsDoug> From Dave K : Wx Situation much the same as briefed earlier; 09z 4 km MO model shows medium cloud clear of Chilbo area by about 1700. Their decision on A/C based on what they can see, & info being fed from Tom C + Chilbo radar (for 2 flights or 1). <FAAMOpsDoug> Have Vizand IR pics from Dave K. Not sure if they can be transferred here. Can put on FAAM site and send link if req. Nice wave cloud on them over Bonnie Scotland... <FAAM_GLUXE> Doug, please pass to DFL-ops decision is only one flight today. Pass on to Cranfiel ATC please <TomC> Sorry I was in a meting , one flight is indeed correct decision <FAAMOpsDoug> OPs informed of 1 flt. Refuel tomorrow at Prestwick as Newcastle busy time and Teeside have h&S issue that would cut science power <FAAMOpsCran> DFL ops informed of only one flight today. Do you have an ETA? <FAAMOpsDoug> ETA approx 3.40? <FAAM_GLUXE> Chilbolton, what is your preference for the rest of the mission: a) keep sampling the supercooled high altitude feature or b) come down beloew cloud to sample lower features? <FAAM_GLUXE> Doug, ETA is 1515 [ChilboltonObser] Assuming we have about 2.5 hrs left, can we sample both? maybe work way up/down in steps; would be good to sample feature at 3000m though, we have a good view of this from lidars. [ChilboltonObser] what do you think? <FAAM_GLUXE> Keith thinking about it. Standby <TomC> back edge of middle level cloud central Wales moving SE [ChilboltonObser] quite a bit of seeding of mid-level supercooled layer by overlying cirrus (top from radar 8500m) at the moment; RHI indicates this is case out to 20km or so. Liquid at 3000m seems to have disappeared overhead. *** DFL_Ops (~vircuser@host86-153-16-34.range86-153.btcentralplus.com) has joined #APPCLOUDS <DFL_Ops> DFL Ops now have the software set up <FAAM_GLUXE> Jim, we've lost 230Vac on the console rack.

Thanks <FAAMOpsDoug> Doug will pass to DFL ETA [ChilboltonObser] OK - very frustrating, conditions are so good! I assume it won't be possible to fix & come back for a second attempt today? <DFL_Ops> yes we have the new eta <FAAM_GLUXE> Chilbolton, it depends what fault it is. Keith will confirm after landing/fault evaluation.
