KWAJEX Surface Fluxes and Boundary Layer
Boundary layer data were collected during KWAJEX from both the University of Virginia site on Meck Island and from the NOAA Ship Ronald H. Brown (RHB). Meck Island instrumentation included an instrumented 10 m tower, an instrumented 10 m boom over the ocean and a tethersonde. The Ronald H. Brown had on board an IMET system similar to that used on buoys and an Environmental Technology Laboratory flux system. Data from these sites are accessible via this page. The Meck 10 m tower data and RHB IMET data as well as field reports can be accessed below.

KWAJEX Tethersonde Data Tethersonde Data: September 1999 The line-mounted tethersonde and data logger are lifted by the balloon (2500 cubic feet, 30 feet long, with a 10-foot diameter) to a maximum altitude of 1500 m. Under operating conditions, the sonde is raised and lowered at a rate of 1 m/s to an operating altitude of 1200 m. These up/down soundings, referred to as a profile, take 40 min to execute (20 min up plus 20 min down). The sonde is kept at 10 m for 10 min prior to ascent and following descent. The sonde is kept at altitude (top of the profile) for 1 min prior to descent. The total profile takes 61 minutes to execute. Soundings are usually made at a rate corresponding to the rawinsonde releases, occasionally increasing to 8-16 profiles/day. For a look at the tethersonde data, click on the links above. |
