From bradley@enmech.csiro.auWed Mar 15 09:41:42 1995 Date: Wed, 15 Mar 95 14:47:08 +1000 From: "Dr. Frank Bradley" To: bourassa@brahms.udel.edu Subject: low-wind data Dear Mark, I received your letter a few days ago asking for data from our west Pacific cruises. There were two cruises described in JGR 96, 3375-3389, 1991 and JGR 98, 22521-22532, 1993. The really low-wind conditions were in the first cruise (1988), but there was also a short period in 1990. Tim Liu kept on at me over a couple of years for this data, but I have been frantically busy with TOGA-COARE, and my earlier work was buried away in odd files and spreadsheets about 5 computers in the past! However, I took the time to scrape it all together for Tim a few months ago so you are in luck. I think that I simply tacked it onto a mail message for Tim, so I will try to do the same for you. Unfortunately I can't locate the letter I wrote describing the set-up, but I can give you the important information and you can e-mail me with specific queries. I work on 15-min time averages, as you will see - there are time gaps in the data when the ship turned, or it rained or the sensors went bad. We worked in local time (=GMT+10) and the columns are date, start time (of the 15'), true wind (m/s), sea temp., air temp, air wet bulb, covariance fluxes of sensible and latent heat (watts/m2). There are no momentum fluxes - ship motion corrections were not good enough, so you will have to assume a drag coefficient to get stresses. Fortunately, the scalar fluxes are insensitive to motion. Wind speeds are corrected using the ship's log, so they are what you want, speed relative to the water. I use a psychrometer, so use your favourite psychrometric eqn. to get humidity from wet and dry bulbs. Sea temp. is measured at about 2m effective depth. In 1988 met data was measured at 9.7m above the water and fluxes at about 7m on the end of the boom. In 1990 met was from 7m on the boom and the fluxes are the mean of measurements from 2 sets of eddy-flux instruments on the boom and foremast (7m and 13m). This should all be described in the papers. See how you go - let me know if the data is readable. You are surely aware that a much more comprehensive data set (including stresses) will soon be available from several ships participating in COARE, including the Franklin. You must also know that Katherine Bouton has a hand in the overall data organisation, so can give you more information about this. Best wishes......Frank **************************************************************** 07-May-88 11:00 1.39 29.87 29.10 24.47 3.4 89.0 07-May-88 11:15 2.15 29.87 28.95 25.09 5.0 92.5 07-May-88 11:30
