Commentary:

People are settling into a comfortable routine now, with only occasional attempts to improve instrument performance. Fishing was a total bust yesterday, but two curious dolphins played near our small fishing craft to lift spirits. The Cessna took today off - 2 days on, 1 day off. Scientists are preparing projector overhead slides for tonight's talk, part of a continuing Tuesday through Saturday "seminar" series for all hands. We continue to hold station within 200 m of the tropical atmospheric ocean buoy.

Cloud Layer Heights:

Ceilometer: 0.5 - 0.8, 2.8 - 2.6, 4.6 - 5.8 km (last 12 hours)

Radar: 0.8 - 1.2 km (last 30 min)

Lidar: 0.5 - 0.85, 2.0, 5.0 km (last 12 hours)
Radiosonde Inversion Height: 0.5 km @ 1729 Z (25 June)

Visual Observations:

Another day with consistent wind and many puffy marine boundary layer (MBL) cumuli clouds, 3-5 m swells, and occasional whitecaps. Considerable convection and rain this morning in the region but these dissipated quickly with no appreciable "action" since.

Instrument Status:

The problems with the Licor CO2 bow tower system were solved - we fixed an inoperative pump. The combined products satellite workstation is functioning well again after software surgery. Interesting convolutions in the MBL layer have been observed by the lidars.
