141000 2653 07912 4809 +0068 102041 +190 +171 104042 033 003



The most important columns for wind speeds are the sixth and ninth columns from the left. For example:

141000 2653 07912 4809 +0068 102041 +190 +171 104042 033 003

The above in bold means that the wind direction is 102 and wind speed in knots is 41 kts.

141000 2653 07912 4809 +0068 102041 +190 +171 104042 033 003

The above in bold means that the highest peak gust during the past 30 seconds is coming from direction 104 and 42 kts.

The second and third columns from the left indicate latitude and longitude, respectively.

It's pressure altitude in feet.

57 knots 10-second wind, 54 knots 30-second wind. That was the pass through the center, as you can tell by the wind change.

The Stepped Frequency Microwave Radiometer (SFMR) developed by ProSensing has been used by the National Oceanic and Atmospheric Administration (NOAA) aboard their hurricane reconnaissance aircraft to measure over-ocean wind speed and rain rate in hurricanes and tropical storms. The SFMR is a compact, airborne radiometer designed to measure surface brightness temperature in 6 frequency bands spanning 4.5 to 7 GHz.
