gnssrefl.quickLook_function2 module

gnssrefl.quickLook_function2.colorful(a, px, pz, lw, fullcolor, ax)

plots the quadrant periodograms

  • a (int) –

  • px (numpy array of floats) – x axis of amplitude power spectrum

  • pz (numpy array of floats) – y axis of amplitude power spectrum

  • lw (float) – line width

  • fullcolor – whether you want full color (if not, it is gray)

  • ax (axis handle) –

gnssrefl.quickLook_function2.goodbad(fname, station, year, doy, h1, h2, PkNoise, reqAmp, freq, e1, e2, hires_figs)

makes a plot that shows “good” and “bad” refletor height retrievals as a function of azimuth

  • fname (str) – filename

  • station (str) – 4 char station name

  • year (int) – full year

  • doy (int) – day of year

  • h1 (float) – minimum reflector height (m)

  • h2 (float) – max reflector height (m)

  • PkNoise (float) – peak 2 noise QC

  • reqAmp (float) – required LSP amplitude

  • freq (int) – frequency

  • e1 (float) – minimum elevation angle (deg)

  • e2 (float) – maximum elevation angle (deg)

  • hires_figs (bool) – whether to use eps instead of png

Return type:

plot is written $REFL_CODE/Files/station/quickLook_summary.png

gnssrefl.quickLook_function2.quickLook_function(station, year, doy, snr_type, f, e1, e2, minH, maxH, reqAmp, pele, satsel, PkNoise, fortran, pltscreen, azim1, azim2, ediff, delTmax, hires_figs, **kwargs)

This is the main function to compute spectral characteristics of a SNR file. It takes in all user inputs and calculates reflector heights. It makes two png files to summarize the data.

This is a new version that tries to picks all rising and setting arcs, not just those constrained to 90 degree quadrants.

  • station (str) – station name (4 char)

  • year (int) – full year

  • doy (int) – day of year

  • snr_type (int) – snr file extension (i.e. 99, 66 etc)

  • f (int) – frequency (1, 2, 5), etc

  • e1 (float) – minimum elevation angle in degrees

  • e2 (float) – maximum elevation angle in degrees

  • minH (float) – minimum allowed reflector height in meters

  • maxH (float) – maximum allowed reflector height in meters

  • reqAmp (float) – is LSP amplitude significance criterion

  • pele (list of floats) – is the elevation angle limits for the polynomial removal. units: degrees

  • satsel (int) – satellite number

  • PkNoise (float) – peak to noise ratio for QC

  • fortran (bool) – whether external fortran translator is being explicitly called.

  • pltscreen (bool) – whether you want plots sent to the terminal

  • azim1 (float) – minimum azimuth in degrees

  • azim2 (float) – maximum azimuth in degrees

  • ediff (float) – QC parameter - restricts length of arcs (degrees)

  • delTmax (float) – maximum arc length in minutes

  • hires_figs (bool) – whether to use eps instead of png


refraction correction used in quickLook. no time dependence.


station (string) – 4 character station name


  • p (float) – pressure, hPa

  • T (float) – temperature, Celsius

  • irefr (int) – refraction model number I believe, which is also sent, so not needed

  • e (float) – water vapor pressure, hPa

gnssrefl.quickLook_function2.set_labels(ax, axisSize, fs)

try to set the appropriate labels depending on the quadrant

  • ax (dictionary) – plot handles

  • axisSize (numpy array of floats) – lists the amplitudes of the various periodograms in a given quadrant pairs of quad (0-3), amplitude

  • fs (int) – font size

  • iaz (float) – azimuth of the arc, degrees

  • a (int) – quad number in funny system
