172900	Photo 6, 11.7N, 1500 m leg, looking south
173300	Photo 7, 11.5, "" 
173500	Approching clouds, right at cloud tops
174200	Skimming Cloud tops
	Note, Clouds are not developing much above this level
175100	Wind shift around 10.25N, turning from 90 @ 10 to 150@5
175430	Pass over top of cloud that had been there previously
	Low aerosol concentrations but very high humidity.
	Clouds are rapidly decaying.
181430	Photo 8 approaching only cloud with vertical development, but
	in dying stages.
181855	CP, 4 m/s vertical velocity, 1gm-3, 100 cm-3, 200 l-1 drizzle
	Interesting behavior of CN, PCASP and FSSP-300 this pass. Large
	increases in CN and PCASP but FSSP-300 decreases in concentration.
182700	VERY low CN concentrations. There has been no sign of new particle
	formation
182900	End of 1500 m leg
183300	SABL turned to look downward.
183300	Starting 2500 m leg.
184000	Photo 9, Same cloud as previously but from southern side and 100 m 
	higher
184045	CP, same cloud but from south end. > 600/l drizzle, much more than
	in 1500 m pass
185645	CP, much younger, > 2 gm-3, same aerosol signature
	Appears to be new development in cloud field.
190600	Photo 10, new cloud
	However, it had an interesting downdraft-updraft pattern, very
	high watetr content, Smooth FSSP and drizzle concentration, little
	sign of entrainment.
191750	Photo 11
191823	CP
1920 30	CP  Both Cloud pass have good vertical velocity structure, i.e.
	up and down drafts
192225	CP
	Looking around, there is a lot of new cloud development.
192810	End of 2500 m cloud pass
193200	Start of 4000 m leg, headed south.
193530	Photo 12, looking at new cloud formation to south. 
	Strong southerly winds throughout the area at this altitude and
	2500 m.
	Elevated CN concentrations at this level. Much higher than lower
	down.

	PCASP and FSSP-300 are also elevated.
192845	CP Fairly wide but older. A lot of structure to look at in the
	 particles and vertical velocity
203300	End of 4000 m pass
203800	Starting 6000 m pass going north. 
204000	Photo 13 looking at cloud to the north that we penetrated at 4000 m
	while going south
204120	CP at -5.5 C. 2D sees ice. The droplet concentrations are very small,
	less than 50, but 260x greater than 700. The aerosol behavior is quite
	different as well. CN goes down but PSASP goes up. FSSP-300 is
	anticorrelated with FSSP-100
205500	Photo 14 Photo of another glaciated cloud that we'll be going through
210010	Very nice cloud pass. 10 m/s updraft, 1 g/m3 water, drizzle, ice
	mixture. Strong aerosol signature. Virtually flat response in 300
	through cloud but more stucture in 100. 
211400	Photo 15 Photo of E-W cloud line near top of research area. We may
	penetrate this on our way back to base.
211600	Very clean region. CN < 200
212500	Photo 16 Photo of last cloud that we'll be going through. Nice
	development.
212940	CP, very well developed cloud. Tops at least to 12km. Could be ice
	multiplication happening. -5.5, 15 m/s updrafts, 5000 l-1 ice/water
	Broad size distribution on FSSP, 260 sizes out to 300 um. Drizzle and
	spatial crystals
215400	CN has increased to over 5000. No response on PCASP. Must be a contrail
	or other pollution source
