Hi,
I need to do some analysis on historic daily radiosonde data I download
from the Wyoming Univ. web page (
http://weather.uwyo.edu/upperair/sounding.html).
I am trying to use the RadioSonde package (V 1.3), but the format of the
files from Wyoming don't match what RadioSonde is expecting.
Has anyone used the Radiosonde package on the Wyoming data?
Here is a sample of the Wyoming file format:

Station information and sounding indices
Station number: 40179
Observation time: 130222/0000
Station latitude: 32.00
Station longitude: 34.81
Station elevation: 35.0
Mean mixed layer potential temperature: 0.00
Mean mixed layer mixing ratio: 0.00
Here is the code I tried:
filename <- 'D:\\Data\\sounding_test3.txt'
datakey <- "------"
varkey <- " PRES"
unitkey <- " hPa"
sample.sonde <- getsonde(filename, datakey, varkey, unitkey)
Error in getsonde(filename, datakey, varkey, unitkey) :
(getsonde): could not find a unique match for the data string
Thanks,
