Sunday 20th March John Cardwell At NCAR 09:12 CHEM BAG OUT 09:20 Earlier around 8:30 columns with asspect ratio 1/10 length 1mm were prevelent, now its gone back to the usuall heavily rimed dendrites fallingin aggregates 1-2mm some dendrite crystals at 1-4mm. Winds are light NE, light snow- The Video has been taken so we have only photographs of the samples, no callibration film starts at 4 following 3 rubbish pictures from my last flight on wendnesday. 0924 snow letting up still agregates 5mm-10mm and crystals 1-3mm heavily rimmed. 0930 breaks in cloud to north-some blue sky 0933 sample#1 100micron heavily rimed column #4 400micron slightly rimmed needle on th end of a melted dendrite branch #5 600micron rimed needle on end of dendrite branch #6 800micron plate with 3 drops of rime < 50 micron #7 #8 500micron column attatched to needle unrimed #9 4 bullet and/or needles 500micron and melted dendrite #10 0942 collected to chem samples 0944 sample#2 Heavily rimmed mush with 2 plates #11 mush with columns #12 400micron column with some rime #13 750micron sheath #14 thin column or sheath #15 400micron bullet and a few plates#16 half a stella with dendritic extensions (2.5mm) #17 1.5mm graupel with column sticking out #18 0945 dendrites look like meltin mush 0948 snow very light - sky breaking up 0950 very small aggregates falling<0.5mm melting on contact, crystal sizes ~1mm 0952 sample#3 mush of semi-melted crystals #19 300-400micron plate? #20 some 3d heavily rimed mush 600micron needles #21 many little dendrite fragments #22 500micron pristine column #23 0959 sample#4 junk(we are between snow & drizzle phase)#24 column with 2 drops on it #25 200micron columnar crystals #26 graupel & remains of broad branch? #27 remains of stella with sector like plates #28 500micron graupel with drops <20 micron on it #29 column with 2 columns growing perpendicular through it #30 10:00 precip is extreemly light- seem to be between snow and drizzle phase sky becoming a little more covered with low sratocumulus clouds. 1005 although we are seeing lots of columnar crystals now, small dendrites are melting in samples. 1007 sample#5 850micron graupel #31 300micron graupel #32 mush 2mm #33 300micron grauple#34 graupel with sheath stuck to it #35 500micron graupel 400micron heavily rimed columns #36 200micron graupel #37 1010 seeing more small graupel now. 1012 very small graupel falling 1015 chem samples #2 taken. 1026 sample6 string of small particles #1 broken branch of dendtite with sector plates#2 pristine hollow column #3 stack of columns #4 1037 sample#7 extreemly small particles falling 300micron capped column heavily rimed #5 string of small cristals #6 100micron column attatched to 100micron drop#7 300micron square graupel#8 <50 micron droplets #9 more droplets #10 small particle #11 mush #12 150micron square grauple#13 1042 snow stopped
