The radiosonde data for the NEAQS 2002 on the NOAA R/V Ronald H. Brown were collected with a Vaisala receiver using
Vaisala RS-80 GPS radiosondes. These sondes directly measured
temperature, pressure and relative humidity. By tracking the position of the
sondes from GPS signals, the sondes horizontal position was measured from
which the horizontal wind speed were calculated.
The raw data files have data at
2 second intervals during the sounding, with the typical assent rates, this gives
data points about every 5 meters. For plotting these data were interpolated onto
a standard 125m altitude grid.
Radiosonde Wind Vectors: In all plots winds speeds are in m/s. The horizontal wind vectors are plotted
with arrows the whose length is proportional to the wind speed. The length of a standard wind vector of 20 m/s is shown at the bottom of each plot. Arrows pointing down indicate wind from the north, Arrows pointing right indicate wind from the west.
