The airplane measures: Pressure [mb*10] Height [gpm] Temperature [deg Celsius*10] Wind Speed [m/s] Wind Direction [deg] The pilot file provided by the Central Weather Bureau is the data output that is fixed in location and sample the atmosphere every twelve hours. The instrument measures: Pressure [mb*10] Height [gpm] Wind Speed [m/s] Wind Direction [deg] The shiptemp file provided by the Central Weather Bureau is the data output from a rawinsonde that was launched from a ship, which are not-fixed in location and sample the atmosphere every twelve hours. The rawinsonde measures: Pressure [mb*10] Height [gpm] Temperature [deg Celsius*10] Wind Speed [m/s] Dewpoint Depression [deg Celsius*10] Wind Direction [deg] The tempdrop file provided by the Central Weather Bureau is the data output from a dropwindsonde, which are not fixed in location and are irregular temporally. The dropwindsonde measures: Pressure [mb*10] Height [gpm] Temperature [deg Celsius*10] Wind Speed [m/s] Dewpoint Depression [deg Celsius*10] Wind Direction [deg] According to the National Hurricane Center typical measurement errors for a GPS dropwindsonde are: pressure ~ 1mb temperature ~ 0.2K relative humidity ~ 5-10% wind < 1m/s The temp file provided by the Central Weather Bureau is the data output from a rawinsonde, which are fixed in location and sample the atmosphere every twelve hours. The rawinsonde measures: Pressure [mb*10] Height [gpm] -1-

Coverts the data into the units needed for assimulation into the ARPS model: Pressure [mb] Height [gpm] Temperature [deg Celsius] Wind Speed [m/s] Dewpoint Temperature [deg Celsius] Wind Direction [deg] 3.
