SF13_S01_satchar_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched at start of NE-SW line in conjunction w/ Terra and other overpasses to characterize region. Largely clear below


SF13_S02_satchar2_qc

Download Data from this drop (NetCDF)

Drop notes: Late winds - acquired single data point at 30s and then lost them again until 6:40. Launched further along NE-SW line that was more convectively active, with a line of clouds to left of plane and sc'd cu below


SF13_S03_satchar3_qc

Download Data from this drop (NetCDF)

Drop notes: Drop launched just ahead (to SW) of convective cell along line. No launch detect, no viable data


SF13_S04_aheadconv_qc


SF13_S04_overconv_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched right above convective turret, very moist on the way down


SF13_S05_NEconvcell_qc

Download Data from this drop (NetCDF)

Drop notes: Generally good drop, slightly late (~1:20) winds. Dropped to NE of main cell, a few shallow inversions and moist layers below but no clearly identifiable clouds


SF13_S06_NEconvcell_qc


SF13_S06_intoconvcell_qc

Download Data from this drop (NetCDF)

Drop notes: **NOTE: actually drop #6 - mixed up channels for #6 and #7 when closing**. Use notes for "drop #6" on this (e.g. late winds, etc). Notes for ACTUAL drop #7 - Good drop. Launched directly into convective turret. Visible precipitation on cockpit windshield, sensor was completely saturated (RH > 110%). Good winds on actual drop #7


SF13_S07_SWconvcell_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched on SW side of convective cell/spine a few minutes after drop directly into main convective core. Some very moist layers below, unsure if sonde penetrated cloud


SF13_S08_convappr_qc

Download Data from this drop (NetCDF)

Drop notes: Late winds acquired around 3:50. Seemed to have GPS location prior to 20s then cut out until 3:40. Launched while in region we were looking for convective turrets in to characterize environment. Potential cloud detrainment around 700-740 mb, likely cloud around 940 mb


SF13_S09_nearconv_qc

Download Data from this drop (NetCDF)

Drop notes: Late winds, similar Bx on this to previous drop - had location around 20s but then lost until ~860 mb. Launched near active convective towers in order to characterize region. Inversion around 700-725 mb, no obvious cloud layers but RH peak at 950 mb


SF13_S10_convtwr_qc

Download Data from this drop (NetCDF)

Drop notes: Late winds, some scattered points higher in profile but generally not acquired until about 5:50 post-launch. Wind signal after that much noisier than usual as well, but was within clear cloud layer at this point so it may be either unreliable or just turbulent. Cloud layer from 725 to 925 or 950 mb


SF13_S11_entrconvtwr_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched into what looked to be entraining convective tower. Moist near top of profile, very dry around 615 mb, but then within cloud and likely precip below about 675 mb. RH tapers off from 850 down but still moist thru to surface. Very variable wind direction (turbulence?) within cloud area as well


SF13_S12_entrconvtwr2_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched while approaching entraining convective tower from other side. Similar depth of obvious cloud layer (~675 to 800) but much more variation in RH and wind direction near top of profile, much drier below ~900 mb


SF13_S13_convtwrno2_qc

Download Data from this drop (NetCDF)

Drop notes: Slightly late winds acquired ~1:10. Launched into second convective tower (not the entraining one) from the opposite direction as approached before. Several visible cloud layers: 575-630 mb, 685-740 mb, 840-900 mb. Massive shift in wind direction (full cycle through compass) from 600-750 mb


SF13_S14_convflnk_qc

Download Data from this drop (NetCDF)

Drop notes: Good drop. Launched on flanks of convective tower/region during straight leg on downward spiral cutting into and out of cloud. Clear air immediately underneath, some convective bubbles below from 850ish-960 mb


SF13_S15_overconvrgn_qc

Download Data from this drop (NetCDF)

Drop notes: Late winds obtained about 2:20 after launch. Launched further within region of convection relative to previous drop. Possible thin cloud at 710 mb, more substantial 775-825mb - some RH wiggles. Also very moist layer at 950 mb but not definitive cloud
