wxprofilers.sonde package

Module contents

wxprofilers.sonde.decode_rrs(bufrin, outputs, outdir='')

Run the RRS Decoder program provided by NOAA.

Parameters

  • bufrin (str) – path to the radiosonde bufr file.

  • outputs (str) – desired output files (see RRS Decoder documentation).

  • outdir (str) – output directory.

wxprofilers.sonde.estimate_pbl(method, height, pressure, temp, rh=None, ws=None, u=None, v=None, land=True, critical_threshold=0.25)

Estimate PBL height using the methods described in [SMC+13].

Parameters

  • method (str) – Method to use to estimate PBL. One of ‘richardson’, ‘heffter’, or ‘liu-liang’.

  • height (ndarray) – Array of heights in km.

  • pressure (ndarray) – Array of pressures in mb.

  • temp (ndarray) – Array of temperatures in °C.

  • rh (ndarray) – Array of relative humidities. Only required when method is ‘richardson’.

  • ws (ndarray) – Array of wind speeds in m/s. Only required when method is ‘liu-liang’.

  • u (ndarray) – Array of U wind components in m/s. Only required when method is ‘richardson’.

  • v (ndarray) – Array of V wind components in m/s. Only required when method is ‘richardson’.

  • land (bool) – Whether the sonde is over land, as opposed to ocean or ice. Only used when method is ‘liu-liang’.

  • critical_threshold (float) – Bulk Richardson critical threshold. Only used when method is ‘richardson’.

Returns

Estimated PBL height in km.

Return type

float
