Commentary:
After yesterday's rains and clouds we decided to stay put for another
24 hours to get better radiative measurements on the windward side of
the island. Seas remain rough so RHIB (small boat) runs to Nauru are being
kept to a minimum. Jeff Otten arrived on board this morning, glad to be
here. The ship has made enough fresh water to allow laundry again; there
was a rush to the machines because most of us were out of clean skivies!
Jeff Hare and Jon Shannahoff observed Atmosphere Radiation and Cloud Station
(ARCS) radiosonde launch procedures to help understand an apparent dry
bias in sondes there. Four island sondes have now been launched from the
Ron Brown and vice versa, but results are not yet in.
