Gas transfer velocities (QuikSCAT normalized radar backscatter) from NOAA Ship Ronald H. Brown cruise RB-08-02 in the Southwest Atlantic sector of the Southern Ocean near South Georgia Island in 2008 (SO_GasEx project)

<p>SO-GasEx Gas transfer velocities (QuikSCAT normalized radar backscatter)</p>

<p>Gas transfer velocities (normalized to Sc=660) derived from QuikSCAT normalized radar backscatter (QSk1p4p1 data set)</p>

<p>Each day's worth of data has (as columns):<br />
date, time, lon, lat, u, v, k, num_k, k46, num_k46, k54, num_k54, kLM, kW, kWM, kN<br />
<br />
u and v are the east-west and north-south U10 wind velocities for that time and location.<br />
k is the Glover radar-based estimate for transfer velocity.<br />
num_* refers to the number of individual QuikSCAT radar returns used.<br />
46 and 54 refer to the inner and outer dual, conically scanning radar pencil beams.<br />
<br />
kLM, kW, kWM, and kN refer to transfer velocities derived from QuikSCAT wind speeds [sqrt(u2+v2)]<br />
using Liss-Merlivat'86, Wanninkhof'92, Wanninkhof and McGillis'99, and Nightingale'00 respectively.<br />
<br />
The data are spatially distributed in Wind Vector Cells (WVC) of roughly 25 km2.<br />
There are 4 to 6 views of at least part of the SO GasEx area each day<br />
<br />
For these data, the area is defined as 30-50° W, 40-60° S.<br />
Potentially, there are 6400 data points per time/date data set.<br />
<br />
The times are given in UTC.</p>
