| sample.sonde {RadioSonde} | R Documentation |
The sample.sonde data frame has 461 rows and 21 columns.
The columns are different physical measurements made during the balloon's
ascent.
data("sample.sonde")
This data frame contains the following named components:
| time | Time in seconds from the ballon's release, a numeric vector. |
| press | Pressure (mb), a numeric vector |
| temp | Dry-bulb Temperature (deg. C), a numeric vector |
| dewpt | Dew point temperaure (deg. C), a numeric vector |
| rh | Relative humidity (%), a numeric vector |
| uwind | East-West component of the wind, a numeric vector |
| vwind | North-South component of the wind, a numeric vector |
| wspd | wind speed (m/s), a numeric vector |
| dir | Wind direction, a numeric vector |
| dz | Ascension rate (m/s), a numeric vector |
| lon | Longitude, a numeric vector |
| lat | Latitude, a numeric vector |
| rng | range, a numeric vector |
| az | azimuth (angle along horizon), a numeric vector |
| alt | altitude (m), a numeric vector |
| qp | QC flag for pressure, a numeric vector |
| qt | QC flag for temperature, a numeric vector |
| qh | QC flag for humidity, a numeric vector |
| qu | QC flag for U component, a numeric vector |
| qv | QC flag for V component, a numeric vector |
| quv | QC flag for ascension rate, a numeric vector |
Quality Control (QC) flags are generated locally at JOSS based on either
automated or visual checks made.
999.0 implies the QC information is missing,
1.0 implies datum seems physically reasonable (good),
2.0 implies datum questionable on a physical basis (maybe),
3.0 implies datum seems to be in error (bad),
4.0 implies datum interpolated (estimated),
9.0 implies datum missing in original file.
